There are two basic types of optical microscopes today .... compound and stereo. Compound microscopes come in both inverted and upright style. The typical visual magnification range of a compound microscope is about 25x to 1000x. Numerical aperture is critical for evaluating lenses on any microscope. Numerical aperture determines resolution. Further, the type of glass in the optical system is important. Lenses are either achromats, fluorites or apochromatics. Lenses can be offered with some curvature of field or totally corrected for a flat field of view across the entire visual image. Eyepiece field of view index (in "mm") is an important factor on any microscope since that determines how much of the sample you will see at one time at any particular magnification. Typical FOV index on oculars will range from 18mm to 26mm. Today many microscopists rarely use the oculars.....the computer displayer is the digital eyepiece in the 21st century.....some microscopes do not even offer eyepieces. This is a major paradigm shift and very "disruptive" to some. Still, setting up the microscope for optimal image quality calls for clean lenses and proper Kohler settings. Lighting is half the battle. LED updates provide very even illumination and saves energy and bulb replacement costs. Basic knowledge of digital image processing (from RAW image acquisitions for example) is helpful. So, after more than 300 years of using the microscope and its many innovations, we are experiencing major changes that are heavily supported by digital technology, creative hardware for motion control and optical developments that exceed the rules established by Mr. Abbe. Will artificial intelligence (AI) play a role in the microscopy of 2030....stay tuned. We need to clean up the environmental mess we are in today. We are doing our best to make changes for the better but we need to get our leaders and governments to take action to save the planet....without a total commitment to this effort all microscopy, self-driving cars and artifical intelligence will not be of much value to our children and their children.
Stereo (AKA dissecting) microscopes are actually two low magnification compound microscopes set at a certain parallax angle so that each eye is seeing a slightly different perspective of a three-dimensional object. Typical stereo microscopes will have a visual magnification range of about 3x to 50x. Student models may be fixed at 10x or 30x and sell for under $500. More advanced "zoom" stereo microscopes may range from 3x to 100x...NOZL apo stereo microscopes sell for over $10,000.00 There are Greenough style (original design) and CMO (central main objective) zoom designs. A CMO (AKA Gallilean) stereo microscope is the best choice for stereoscopic vision and/or photomicroscopy. Some Greenough styles will have a dedicated camera port integrated into the viewing tube. If the main mission is to have first-class digital imagery you will want to explore the "macrozoom" (AKA photomacroscope). These instruments are technically compound optical microscopes with a relatively low magnification range. Read more about a third microscope option from Infinity Photo Optical in Colorado. They do not produce "stereo 3D" (S3D) images! It is important to note that a digital camera mounted on any compound or stereo microscope will not give you S3D. See our Digital and Video Microscopes page on one alternative solution for true S3D digital imaging.

Many pathology departments who are considering (validating) WSI (whole slide imaging) for virtual slide viewing might take a look a this unique image stitching solution from www.microvisioneer.com in Germany. Here you will see Jim Averill seated next to a conventional microscope with the newest global shutter camera (Sony Pregius sensors 3 or 5MP) mounted on the trinocular camera port. manualWSI is the name of the software that runs in Windows. The user "stitches" the tiles using the coaxial, manual mechanical stage. You then view directly on your computer displayer and end up with a virtual slide that may then be uploaded to any number of free cloud viewers or quickly share the virtual slide with others via the internet.
Now available for manual WSI with the AR system www.augmentiqs.com
This is ideal for a pathology group or lab that is in the validation mode for their WSI solution. Use an existing manual microscope and just add the software and camera to an existing computer meeting the manualWSI requirements.
Prices for the camera and software start at less than $5,000.00!
Most economical WSI solution for those wanting to scan special cases for archiving or image sharing with associates.
Here you will see RetroBOT being controlled with our original remote control for focus (Z) and slide movement (XY). The stage is belt driven by two precision stepper motors. End stops in both X and Y have the ability to establish limited range of movement for a 3x1" glass slide. Shown with a color camera mounted on an older Olympus BX microscope, the RetroBOT with joystick controller would be ideal for use by disabled individuals. Note the ergonomic binocular tube for tilting the oculars. If a disabled microscopist cannot view through oculars they would be able to remotely control the slide scanning and focus and view directly from a 4K display monitor. The RetroBOT is supplied with API and everything needed for computer control of all functions. Such a system then could be used by a disabled microscopist without the need for the joystick control. Open source ARDUINO controller.
Alternative solutions for those with disabilities (including low vision) can be discussed. RetroBOT is affordable and very flexible. We are seeking early adopters, innovative OEM third party projects as well as developers seeking computer integration of microscopes.....including AR, VR and AI.
Developer models are available at this time.
PRICES START AT LESS THAN $2000.00
The TS-160 is the perfect solution for those wanting very high resolution micro and macro digital images. Use TS-160 with either its own "macro" lens (as shown in the photo) or simply remove that lens and replace it with the high aperture "micro" lens. Yes, this is a complete microscope and not a zoom lens. That large knurled ring in the middle of the TS-160 allows one to focus from 18mm (working distance) to INFINITY! The aperture diaphragm allows one to "stop-down" to the best setting for resolution and contrast (and depth of focus). Use TS-160 with Zerene Stacker in the manual mode....simply turn that internal focus ring on TS-160 for the focal planes you desire.....do this all on your computer displayer in "live view" mode. A new "Robusto" version of TS-160 is now offered for digital cinematography applications...or use the 2K/4K cine feature found on most modern DSLR and MILCs. TS-160 is the best choice for high performance digital photography. You will not see any results like this using a stereoscopic microscope. TS-160 will give you results equal to or better than NOZL photomacroscopes for less than $3,000.00...and made in America. Mount the TS-160 on a tripod, tabletop copy stand, stereo microscope stand (with or without backlighting). Twin head flash heads are ideal for both macro and micro lighting. Zerene even controls the flash signal along with shutter initiation. Use it in the field for everything from flowers to spiders. Nothing like this on the market.
Visit the Infinity website but bring your lunch or a big cup of java......lots of really good info on this site along with photo samples, tech specs and discussion of the full line of microscopes from Infinity Photo Optical. Check out the Infinity "KC", "MS" and "K2" while on the site: www.infinity-usa.com
The KC-Videomax is a long-distance microscope using series of special IF-Series front objectives. KC may also be used for coaxial illumination with any infinity corrected microscope objective such as Mitutoyo or NOZL lenses for samples without coverglass. Infinity Photo Optical's own Achrovid objectives (2x-10x) are selected for economical long working distance requirements. The KC also has a group of macro objectives called CF-Series. Use your own favorite infinity corrected microscope objectives from NOZL (2x, 5x, 10x etc). We have adapters for using all popular threaded objectives on the KC. This is a telecentric kit that is ideal for Z-STACKING....plus it is available for use with FULL FRAME SENSOR DSLR and MILCs. Compact, reasonably priced and MADE IN AMERICA. KC shown with IF front objective and large format adapter ring. Mounts to your existing copy stand with 1/4-20 fixture shown. This is a COMPOUND MICROSCOPE and NOT a ZOOM LENS!
The MS is perfect for use in the field or laboratory. Shown with the USA-Made Arcturus iPhone adapter and our special 10x ocular with c-mount adapter, this microscope will focus from 18mm to infinity. Remove the iPhone adapter and you have a male c-mount thread to attach any small format camera of your choice. Perfect for the classroom and training operations. Includes two extender tubes to alter magnification with internal fine focusing and aperture diaphragm for DOF and contrast control by the user. Comes with a 1/4-20 clamp for mounting to your copy stand or tripod. Try doing this with a more expensive stereo microscope or zoom lens.....MS is NOT a zoom lens. Rather this is a complete microscope that is designed for portability and high resolution. About $2,000.00 with an iPhone adapter. Digital image of a Maryland stinkbug eyeball. No Z-stacking but pretty good detail. Much better than you would get with a stereoscopic type microscope. A twin-tube macro flash unit was used for this image.
A good stereoscopic microscope is ideal for viewing 3D samples so that each eye views a slightly different angle on axis.....the brain then fuses the left and right image so that one perceives DEPTH CUES. Stereopsis then is perfect for dissection applications or micromanipulation. Photomicroscopy is possible but the main mission of a stereo microscope is ocular viewing....photography is compromised somewhat since the 2D single camera sensor is only seeing one of the two optical channels. Measurements will be difficult due to parallax error...an off-axis view of the sample. Single optical channel microscopes (compound type....including all of the Infinity Photo Optical instruments) are 2D in nature but we are using the central "sweet spot" image without parallax error or reduced numerical aperture. Stereo microscopes are mostly low n.a. systems. Some microscopes are now offered with apochromatic central lenses for higher numerical aperture numbers and chromatic aberration correction....very nice but very expensive. The MEIJI "RZ" is our new research quality stereoscopic microscope. Zoom is 1:10 and it is CMO (central main objective) designed....yes, an apo front optic is available in addition to achromatic 0.5, 0.7, 1.0, 1.5 and 2.0x central main objectives. Binocular ergo tubes (0-50 degree variable) are offered. Prices begin at $4,000.00 with a fixed binocular, 10x oculars and 1x achromat CMO. Photo/video tubes available as well as a large selection of support stands (transillumination base for brightfield or darkfield backlighting is shown). LED and fiber optic incident lighting is also available (see our ACCESSORIES SECTION). High end NOZL stereo microscopes with apochromatic correct sell for between $10-20,000.00. MEIJI...the third largest microscope maker from Japan.
