Mirror Mount, Thin Optic, 0.5 in., 100 TPI, 2 Locking Allen-Keys

The P50-At21 is a kinematic optic mount specifically made for thin 0.5-in. optics. The mount features a fully threaded design to allow for mounting of lens tubes or other items with 0.535-40 (SM05) threads. It uses two threaded retaining rings to secure optics having a thickness of 3 mm or less. The mount has standard features like a 0.63-in. optical axis height, two 100-TPI hex key locking actuators, and an exceptionally thin 20-mm nominal profile. The P50-At21 is designed with a center clearance hole for #8 or M4 screws.
