Model KC/S InFocus Video Microscope

Containing Infinity's R&D 100 award-winning InFocus system, the KC/S has a working distance from infinity to 405mm (15.94 in.). With IF-Series objectives, the KC/S can be used as close as 63mm (2.48 in.) at a magnification of 3.2x directly onto the CCD sensor (128x on 13-in. monitors). This magnification can be further increased with accessory amplifier tubes.

The KC/S is a true long-distance microscope. It uses objectives with apertures greater than stereomicroscopes and virtually equivalent to compound laboratory-type microscopes—but at many times their working distances. It works like a regular compound laboratory microscope as well. The KC/S can be equipped with a variable iris diaphragm (included in ST and SD models) to set the proper aperture for greatest contrast and resolution and to control light throughput with IF series objectives. Since the highest aperture at which objective can be used is not necessarily the best aperture to use, all laboratory microscopes (the KC/S is no exception) function best when used at c.75% of their potential apertures. This is known as the "Nelson 3/4 rule" and only Infinity's long-distance microscopes allow this principle to be utilized. Contrast must always be matched to resolution—and the KC/S can do precisely that. Used properly, the KC/S can provide results comparable to those of much larger catadioptic (mirror/lens) systems—at a fraction of their size and weight. That, not to mention that the KC/S is a refractor (just like regular laboratory microscopes) which means that central obstructions are not imaged as distracting artifacts.

But there is much more. Since the KC/S Main Body is a true infinity-corrected microscope with built-in internal focusing, it can be used with supplemental microscope objectives beyond those for long-distance purposes. In fact, most of the world's leading makes of infinity-corrected objectives can be used with it—literally to the potential limits of optical microscopy—in transmitted or coaxial (-epi) illumination!

Although the standard KC/S is supplied in a basic 30mm C-tube configuration, we now offer the KC/S as a larger KC/ST—or its dual-port version, the KC/SD. The ST and SD models can be equipped with accessories for larger formats and more advanced techniques.

The amazing KC/S: Small—but powerful. Please see the PDFs for more details. Contact us for more information keyed to your specific application.
