OPTICAL SYSTEM
- Widefield 10x eyepiece with revolving pointer.
- 45° inclined head for ease of viewing when seated.
- Head rotates 360°.
- Color coded 4x, 10x, 40xR objectives provide 40x, 100x
and 400x magnification.
- Revolving triple nosepiece with positive click stops for
easy, precise magnification changes.
ILLUMINATION
- 115v 15-watt sub stage illuminator with on/off switch
permanently factory mounted.
- Optional Cordless LED Illuminator (109-LED) - lighting
equivalent to a 20-watt tungsten bulb, rechargeable NiMH
batteries, auto cutoff recharger, on/off switch with
rheostat control.
Note: With bright artificial
or natural light, mirror model will provide very adequate
illumination. However, if light conditions are poor, it
is necessary to incline the microscope on its inclination
joint for the mirror to catch sufficient light, positioning
the inclined eyepiece at a less convenient angle. Therefore,
for a poorly lit environment, we recommend selection of
109-L or 109-LED, with electric illuminator.

- Rack and pinion focusing.
- Slip clutch protects focusing mechanism from over-turning.
