Micrometer Adjustable Slit, 77250 Monochromator

The 74001 Micrometer Driven Slit Assembly allows continuously variable width from 4 μm to 3 mm, and continuously variable height from 3 mm to 12 mm with ±10 μm repeatability. ±10 μm accuracy from 4 to 250 μm, ±5% from 250 μm to 3 mm. This slit assembly uses a precision micrometer drive to adjust the width. Monochromators and spectrographs require one input slit. Monochromators also require slits at each output port.
