MDE863 - Adjustable Slit
- Adjustable slit
- Micrometer adjuster
- Very smooth backlash-free motion
- Based on precision dovetail slide
The model MDE863 Adjustable Slit comprises a pair of knife edges mounted onto an MDE255M precision slide. One knife edge is fixed whilst the other is adjustable to give a maximum opening of 10 mm, with a sensitivity of 1 µm. The micrometer is graduated at 10 µm intervals.
|Aperture height||18 mm|
|Adjuster micrometer||0.01 mm graduations|
|Slit width range||0 to 10 mm|
|Slit parallelism||≤ 0.03 mm|

Note: Surface mating with these micropositioners must be truly flat. Unflat surfaces or overtightened screws will cause the slide motion to be jerky and stiff due to distortion. Dovetail slides, unlike miniature ball slides, are unlikely to be permanently damaged by temporary distortion, as the load is supported on a comparatively large area.
