The 9876-K Tiny Corner Mirror Mount is our most compact mount for applications where space is truly tight. Designed with the same mechanical principles as our larger classic mounts, it offers over 2 mm of pure translation and ±4° of tilt for 0.5 inch (12.7 mm) diameter optics. It has 6-80 adjustment screws and #2 (M2) clearance holes for mounting. All our Tiny mounts come standard without knobs. If you need knobs to adjust these mounts in your experiment, you can order our Model 9365 Tiny knobs.
