45° Optic Mounts
This 45° mount assembly can be used when the need to adjust the optical beam height arises. The housing accepts Ø1" optics, such as mirrors. The rear through hole allows for use of Ø1" beamsplitters and has a transmitted clear aperture of Ø0.326" (Ø8.3 mm). When used with a mirror, the clear aperture of the mount is Ø0.707" (Ø18 mm).
The H45B2 ships fully assembled with optic housing, post, and mounting base. The optic is held in place with a nylon-tipped 8-32 setscrew, which accepts a 5/64" (2 mm) balldriver.

Ø1" beamsplitter secured in the H45 45° mount. This assembly is mounted in a KM100 kinematic mount with beam trajectories indicated by the red arrows.
This 45° mount directly accepts Ø1" optics. Two perpendicular through holes allow for the use of beamsplitters in addition to non-transmitting optics, such as mirrors. The optic is held in place with a nylon-tipped 8-32 setscrew, which accepts a 5/64" (2 mm) balldriver.

Secure the H45CN to a Ø1.5" Post using the BE1 Base
This 45° mount is ideal for holding Ø2" mirrors or beamsplitters at a 45° angle within an optical setup. Two through holes, located at a 90° angle with respect to each other, allow this mount to be used in applications where beamsplitters are needed. The rear through hole allows for use of Ø2" beamsplitters and has a transmitted clear aperture of Ø1.091" (Ø27.7 mm). When used with a mirror, the front clear aperture of the mount is Ø1.318" (Ø33.5 mm). An 8-32 nylon-tipped setscrew, located at the top of the mount, secures the optic in the bore. Optics must be at least 0.18" (4.6 mm) thick to be used in this mount.
This angled mount can be held in any of our unthreaded Ø2" kinematic mirror mounts, such as the KM200, via the setscrew included with the kinematic mount. The 45° mount can also be attached to a Ø1.5" post using a BE1 Ø1" post base. The image to the right illustrates the correct installation of the BE1. Please note that you must secure the H45CN mount to the post prior to installing the mirror, as the BE1 will only fit through the angled hole in the mount.
The MA45-2(/M) 45° mounting adapter is designed to allow our KM100 and KM200 mirror mounts to be securely held at 45° with respect to an optical bench. The beam height of the KM100 and MA45-2(/M) combination mounted on a UPHA base is 2" (50 mm). The beam height of the same assembly using the KM200 is 2.49" (63.2 mm).
An 8-32 (M4) tap is provided on the 45° flat surface of the adapter so the KM100 can be directly fastened to that surface with a cap screw. This mounting adapter can be secured to our post holder bases via a 1/4"-20 (M4) cap screw.
