Prior Scientific has announced the FB201 co-axial coarse and fine focusing block, designed for OEM microscopy applications where precise fine focus adjustment is required.
Rack and pinion mounting allows the FB201 to produce smooth, precise focusing over 29 mm of travel. A large coarse focus mechanism incorporates a slip clutch and tension adjustment. Fine focus adjustment control is graduated in two micron divisions throughout the coarse focus range. The focus block can be easily adapted to various mounting configurations and can support up to 5kg.
