If you have a CS-mount camera and a C-mount lens, you can add a 5mm spacer to obtain the correct focus. If, however, you have a C-mount camera and a CS-mount lens, correct focus cannot be achieved.

Sensor sizes are often designated using fractions such as 1/1.8" or 2/3" which are larger or smaller than the actual sensor diagonal dimension. This sensor size designation goes all the way back to standard sizes given to Vidicon camera tubes developed in the 1940's and is unfortunately, still in use today.

A c-mount adapter for your microscope without a lens in it, is merely a connector for your camera. What you'll get is a "direct image" on the monitor screen, which is more magnification than what is seen in the eyepieces due to the inherent magnification with image sensors and microscopes. While this arrangement is fine for some users, others require an image on the monitor that looks more like the Field Of View, or FOV, that is seen in the microscope eyetubes.

CS Lens

C- and CS-mount lenses are both threaded lens mounts found on most industrial CCD cameras and lenses. The difference between C and CS-mount equipment is the distance between the flange of the lens (the part of the case that butts up against the camera) and the focal plane of the lens (where the CCD sensor must be positioned). This is known as the flange back distance.

Meiji Techno cameras have "CS" mounts so they can also accommodate "C" mounts when a spacer is first threaded onto the camera providing the additional 5mm per the "C"-Mount specification as shown above.

In a finite optical system of fixed tube length, light passing through the objective is directed toward the intermediate image plane (located at the front focal plane of the eyepiece) and converges at that point, undergoing constructive and destructive interference to produce an image. The situation is quite different for infinity-corrected optical systems where the objective produces a flux of parallel light wavetrains imaged at infinity (often referred to as infinity space, and labeled in the tutorial window), which are brought into focus at the intermediate image plane by the tube lens. It should be noted that objectives designed for infinity-corrected microscopes are usually not interchangeable with those intended for a finite (160 or 170 millimeter) optical tube length microscope and vice versa. Infinity lenses suffer from enhanced spherical aberration when used on a finite microscope system due to lack of a tube lens. In some circumstances it is possible, however, to utilize finite objectives on infinity-corrected microscopes, but with some drawbacks. The numerical aperture of finite objectives is compromised when they are used with infinity systems, which leads to reduced resolution. Also, parfocality is lost between finite and infinity objectives when used in the same system. The working distance and magnification of finite objectives will also be decreased when they are used with a microscope having a tube lens.

The C-mount lens specification for flange back distance is 17.53 mm, and on CS-mount lenses it is 12.53 mm. However, on Point Grey cameras, these physical distances are offset due to the presence of both a 1 mm infrared cutoff (IRC) filter and a 0.5 mm sensor package window. These two pieces of glass fit between the lens and the sensor image plane. The IRC filter is installed by Point Grey on color cameras; in monochrome cameras, the IRC is replaced with a transparent glass window. The sensor package window is installed by the sensor manufacturer. The refraction of these glass components requires an offset in the flange back distance from the nominal values.

To operate the tutorial, use the Reference Focal Length and Objective Focal Length sliders to alter the specifications of the virtual infinity optical system. The objective magnification (M) is calculated by dividing the reference focal length (L) of the tube lens by the objective focal length (F). As the critical focal length parameters of the microscope are varied, this calculation is automatically performed and the result is continuously updated and displayed in the space to the right of the objective drawing in the tutorial window. For example, a reference focal length of 180 millimeters and an objective focal length of 18 millimeters yield a magnification of 10x. The objective working distance is also presented graphically and updated as the microscope focal lengths are adjusted.

Meiji Techno C-Mount Adapters with reductions lenses are easily removed from the optical path by simply removing the black colored lens piece and then re-attaching the camera to the tube directly when higher on-screen magnification is needed. Click HERE to try our On-Screen Magnification Calculator Page to see how different combinations of objectives, auxiliary lenses, c-mounts, camera chip sizes and monitor sizes effect the magnification seen on the monitor screen.

As image resolution is most desirable in all microscopy applications, 1/4" chips are just not well suited for microscopy while the 1/2" and 2/3" chip cameras strike a better balance between magnification, resolution and the size of the virtual image that the camera is seeing which to the eye appears much like a flashlight beam.

The V-5MM is included with all the CK Series Analog Video Cameras that Meiji sells and supports. The adverse result that can happen when a spacer is not installed is a phenomenon known as "vignetting".

The tutorial initializes with the major optical train components (condenser, specimen, objective, tube lens, and eyepiece) of a virtual infinity-corrected microscope appearing in the window. A beam of semi-coherent light generated by the source passes through the condenser and is focused onto the specimen plane, subsequently being collected by the objective. The parallel flux of light rays exiting the objective are focused by the tube lens onto the intermediate image plane positioned at the fixed diaphragm of the eyepiece. The distance between the tube lens and the fixed eyepiece diaphragm is adjustable within a range of 160 and 200 millimeters using the Reference Focal Length (L) slider (equivalent to the tube length in older microscopes). In addition, the objective focal length can be varied from 2 to 40 millimeters by translating the Objective Focal Length (F) slider. As these sliders are translated, the individual components of the virtual microscope are readjusted to new positions.

As previously listed, the basic optical components of an infinity system are the objective, tube lens, and the eyepieces. The specimen is located at the front focal plane of the objective, which gathers light transmitted through or reflected from the central portion of the specimen and produces a parallel bundle of rays projected along the optical axis of the microscope toward the tube lens. A portion of the light reaching the objective emanates from the periphery of the specimen, and enters the optical system at oblique angles, advancing diagonally (but still in parallel bundles) toward the tube lens. All of the light gathered by the tube lens is then focused at the intermediate image plane, and subsequently enlarged by the eyepiece.

Infinity-corrected microscope optical systems are designed to enable the insertion of auxiliary devices, such as vertical illuminators and intermediate tubes, into the optical pathway between the objective and eyepieces without introducing spherical aberration, requiring focus corrections, or creating other image problems. In a finite optical system, light passing through the objective converges at the image plane to produce an image. The situation is quite different for infinity-corrected optical systems where the objective produces a flux of parallel light wavetrains imaged at infinity, which are brought into focus at the intermediate image plane by the tube lens. This tutorial explores how changes in tube lens and objective focal length affect the magnification power of the objective in infinity-corrected microscopes.

As one can see, image sensors in cameras are actually quite small. The smaller the sensor, the more inherent magnification. The larger the sensor, the better the resolution with less magnification.

The tube length in infinity-corrected microscopes is referred to as the reference focal length and ranges between 160 and 200 millimeters, depending upon the manufacturer. Correction for optical aberration in infinity systems is accomplished either through the tube lens or the objective(s). Residual lateral chromatic aberration in infinity objectives can be easily compensated by careful tube lens design, but some manufacturers choose to correct for spherical and chromatic aberrations in the objective lens itself. This is possible because of the development of proprietary new glass formulas that have extremely low dispersions. Other manufacturers utilize a combination of corrections in both the tube lens and objectives.

To compensate for too much mag or to match more closely the microscope FOV, one can use c-mounts with reduction lenses in order to adjust the field of view seen on the monitor. The reduction lens you require will depend on the chip size of your camera so if your camera has a 1/2" image sensor, you'll want the 0.45X c-mount. See the table at right for other adapter suggestions. Experienced users have an assortment of reduction lenses to accommodate different situations or specimens as c-mounts are relatively inexpensive.
