The LBTEK Fixed Pellicle Mount is suitable for not requiring the adjustment of pitch and yaw. It can accommodate Ø25.4 mm thin-film polarizers and features an M4 countersunk mounting hole at the bottom for posts and other optical components. When manually rotating the component on the post, it provides a gimbal-like motion. The mount adopts an embedded mounting method, where a rubber-tipped screw presses against the front of the pellicle's housing. This approach effectively prevents stress-induced damage to the pellicle membrane that may occur with side-mounted fixation.
