Elliot Scientific Ltd. has launched the KML131 locking kinematic mirror mount for applications that require beam steering and locking. The device features stainless-steel adjusters with brass adjuster nuts and hardened inserts. Three 1/4-80 hex drive adjusters with removable knobs provide accurate positioning over ±4° and can be locked with a quarter turn of the lock ring. A nylon-tipped setscrew holds the 25-mm optic firmly in place. An M4/#8-32 clearance hole mounting allows left- and right-handed operation.
