1. Convert the NIKON trinocular microscope phototube/head/port (have standard 38 mm(1.50 inch) outer diameter for the insertion end to phototube) to traditional C-Mount type(25.4 mm or 1 inch diameter with 32 threads per inch);
2. With different built-in reduction lens (1.2X,1X, 0.8X, 0.70X, 0.55X, 0.35X) for achieving better field of view from microscope trinocular head(suitable for 4/3” 1”, 2/3”, 1/1.8”, 1/2”, 1/2.5”, 1/3” or 1/4” inch CCD or CMOS sensor chips);
3. Can be installed in UIS trinocular tube such as : NIKON E100, E200, 50i, 55i, 80i, 90i, Ni series, Ti Series, SMZ800, SMZ1000, SMZ15000 biology microscopes and industrial microscopes;
4. Build of material: stainless steel material for the C-Mount end and spray-painted aluminum for the phototube end ;
5. Telecentric optics with low light deficiency;
6. Parfocal with different microscope objective lenses;
7. Diffraction limited MTF;

8. Aperture totally coupled with UIS microscope objective’s exit pupil;
The adapters work for the following microscope series: NIKON microscopes UPRIGHT: Alphaphot-2, Eclipse series (requires YT-tube 92306), Labophot-2, Optiphot-2 Optiphot 100S, 150, 200, 300 Stereo: SMZ-10A, SMZ-U, SMZ-1000, SMZ-1500 METALLURGICAL: EPIPHOT 300/200 MEASURING: MM-40, MM-60 INVERTED: Diaphot 300/200 TS100-F TE2000.
