AI Overview

Reflecting rhomboid prisms are precision optical components that laterally displace a laser beam or imaging path by a set distance (equal to the prism length) without inverting, reverting, or changing the direction of the image. Typically manufactured from N-BK7, these prisms utilize total internal reflection (TIR) on two parallel faces oblique to the input/output surfaces.

Key Features and Applications

Beam Displacement: Ideal for shifting the optical axis in imaging or laser systems.
Maintain Orientation: Does not alter the image orientation or beam angle.
Interpupillary Adjustment: Often used in pairs for binocular instruments (e.g., rangefinders, stereoscopic microscopes) to adjust the distance between eyepieces.
Structure: Composed of two parallel transmitting faces and two parallel reflecting faces, usually at 45°.

Materials: Frequently N-BK7 or other specialized glass, often AR-coated (e.g., 1260–1650nm AR coating).
Customization: Available in varying sizes, often with custom coatings for increased angular range, according to options from UNI Optics.
Common Suppliers: Edmund Optics offers various models, and Knight Optical provides stock options like the 16x15x42mm variant.
Types: Standard, miniature 0.5.11, and infrared-specific (e.g., Germanium) for IR imaging systems.
