Special Features:

Translates the line or sight laterally using an optical flat; cast aluminum housing; used on the leico t-2 telescope barrel only; porm 0.100 to 0.001 inch range; green polyurethane paint finish; glass window dust cover for protection of the optical flat

Properties:

One or more components, specifically designed for measuring and indicating and/or recording very small linear distances in air or across nonmetallic materials by mutual inductance variation or variation in self-inductance, these properties being essentially a linear function of distance from a reference metallic surface to an inductance probe.
