HD400 Optical Comparator
Model: HD400
Dual-lens horizontal benchtop optical comparator for instant switching between two magnifications.
About the HD400 Optical Comparator
The HD400 adds a two-lens mount to the 400-series benchtop platform, so operators can switch instantly between two magnifications without changing lenses. It is fitted with a 16" (400 mm) screen and 16" travel workstage, helix adjustment for thread-form inspection, and accepts five interchangeable bayonet lenses. Automatic optical edge detection, motorized axes and a swing-away lamp house are optional.
