RT & LT Objective Transmission
vacuum shroud for transmission measurements with an RT objective and a cold fiber/objective
This vacuum shroud is designed for transmission experiments with one room temperature objective, and one cold objective (LT-APO series). The min. working distances are 13 mm (RT) and 0.65 mm (LT) respectively. The shroud features 4x6 M6 breadboard mounting holes for the external objective, and and L-shaped sample holder with a 3 mm clear aperture as well as a thermalized mounting post and bracket for the LT-APO objective. It can host a stack of xyz nanopositioners for the sample, and upon request can potentially be modified to host another set of xyz positioners for the cold objective.
