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.
The threaded aperture versions are designed to hold thin optics and lenses with threaded retainers. P100-At28 and P100-At38 include not only a threaded retaining ring but also a protective Delrin spacer to prevent scratching the optic's coating or surface as it is secured. P50-At21 and P200-At28 feature a fully threaded design and include two retaining rings for holding the optic. They also allow for mounting of lens tubes or other optical components with matching threads. Vacuum pick-up tools and spanner wrench facilitate installation and removal of the optic.
Performa-i Series industrial mounts feature Allen-key adjustments to save space and prevent unintended adjustment. A flexure lock is built into the mount body and exerts a tangential force on the screw to prevent rotation. Adjustment and locking actions are accomplished using a single tool from the same side of the mount.
The design of the these mounts follows kinematic principles to ensure the highest stability and precision. Each degree of freedom is constrained just once using the Cone, V, and Flat configuration.
