English Prism Mounts

English Prism Mounts feature a steel post and anodized aluminum arm which eliminates obstructions in the optical path while still maintaining a secure position on the optic. Ideal for prisms and cube beamsplitters with a maximum height of 55mm, this prism mount features a V-cut clamp made of scratch resistant Delrin® to prevent damage to optics. The Prism Holder is also available as a complete assembly with the Rotary Optic Mount, which allows smooth manual 360° rotation of the prism. English Prism Mounts   have a locking knob that keep prisms securely positioned for increased repeatability.
