The KM05BP, KM100BP, and KM200BP combine the kinematic adjustment of our most popular mirror mounts with an easy-to-use front plate designed specifically for our Ø1/2", Ø1.0", and Ø2.0" pellicle beamsplitters. The front plates come equipped with two clearance slots that accommodate the included 2-56 cap screws used to secure the position of the pellicle within the mount. These mounts feature phosphor bronze bushings, high-quality 3/16"-100 TPI or 1/4"-80 TPI adjuster screws (see below for details), and hardened inserts at all key wear locations. All adjusters can be actuated using a HKTS-5/64 hex key thumbscrew or other 5/64" hex key. An optional accessory, the LN19100 or LN2580 bronze locking nuts, are available to lock the 3/16"-100 TPI or 1/4"-80 adjusters, respectively, once the desired position is reached. The Ø1/2" version features 8-32 or M4 x 0.7 tapped mounting holes, while the Ø1" and Ø2" versions feature #8 (M4) counterbores for post mounting. The mounts are fabricated from black anodized aluminum.
