PB-3620 binocular microscope
Brand: GEMMY Industrial | Category: Medical Equipment
A binocular microscope whose measuring single tube is inclined at 30 degrees rather than the 45 degrees of the rest of the PB range, rotating through 360 degrees with interpupillary distance from 48 mm to 75 mm. WF10X and WF16X eyepieces pair with achromatic objectives of 4X, 10X, 40X and 100X. The double layer mechanical stage measures 135 x 125 mm with a 70 x 50 mm moving range, over an N.A. 1.25 Abbe condenser with iris diaphragm. Focusing is coaxial coarse and fine on a rack and pinion mechanism with a fine focusing scale value of 0.002 mm, and illumination is a built-in 6V 20W variable brightness source.

- PB-3730 trinocular microscope
The trinocular member of the PB range, with a triple measuring single tube at 45 degrees rotating through 360 degrees and interpupillary distance from 48 mm to 75 mm. It carries WF10X and WF16X eyepieces with achromatic objectives at 4X, 10X, 40X and 100X, and a 140 x 130 mm double layer mechanical stage with a 70 x 50 mm moving range. The third port is intended for a CCD digital camera, which GEMMY lists as an optional accessory together with plan objectives and a connection adaptor. Focusing is coaxial coarse and fine with a 0.002 mm fine scale value, under 6V 20W variable brightness illumination.
- PB-3320
A binocular laboratory microscope with a measuring single tube inclined at 45 degrees and rotating through 360 degrees, with interpupillary distance adjustable from 48 mm to 75 mm. It is supplied with WF10X and WF16X eyepieces and a four position achromatic objective set of 4X, 10X, 40X and 100X. The double layer mechanical stage measures 140 x 130 mm with a 70 x 50 mm moving range, over an N.A. 1.25 Abbe condenser with iris diaphragm. Coaxial coarse and fine focusing runs on a rack and pinion mechanism with a fine focusing scale value of 0.002 mm, lit by a built-in 6V 20W variable brightness lamp. GEMMY publishes no product name for this model, only the model number PB-3320.
