RT Transmission

vacuum shroud for transmission measurements with RT objectives

This vacuum shroud is designed for transmission experiments using two room temperature objectives positioned with the optical axis in lateral direction. It can host nanopositioners for xz motion to move the region of interest in the sample plane, while focussing of both objectives is intended to be provided externally. The dedicated transmission sample holder features a clear aperture of 3.5 mm. The minimum working distance is 4.5 mm / 7.5 mm respectively from the two sides, and the max. diameter for the room temperature objectives is 40 mm. Customizations of the shroud and positioner configuration are possible on request.
