Optical Slits:
Crossed entrance slit SXM-1 (adjustable pinhole)
Micrometer-driven with opening width adjustable from 7µm to 2000µm (diagonal of the square aperture) or from 5 µm to 1414 µm (side of the square aperture). Microscrew reading accuracy +/- 1 µm Step 0.125 µm.

Non-magnetic crossed slit SXM-2
(non-magnetic adjustable pinhole) The slit is composed of non-magnetic materials, tested in magnetic field not less than 1.5 T; other features are the same as for the model SXM-1.
Standard input slit S0

Standard output slit S1

Standard slits for M266 & M833 are micrometer and motor-driven. MSA-130 contains micrometer-driven slits.
