BP108 Pellicle Beamsplitter Post Mounted Using a BP107 Fixed Pellicle Mount
These fixed pellicle beamsplitter mounts are a compact and unobstrusive solution when kinematic tip and tilt of the pellicle are not required (see our Kinematic Pellicle Mounts). The post mountable design features an 8-32 (M4) counterbore directly under the optical surface of the pellicle in order to provide a gimbal-like motion when manually rotating an assembly in a post holder.
Thorlabs' Pellicle Beamsplitters are conveniently "dropped into" the mount via slotted supports. This feature helps prevent damage to the extremly delicate pellicle membrane as a result of excess handling. Secure the pellicle's position using the two 2-56 cap screws included with the mount.
