Right Angle Prisms from Rocky Mountain Instrument Co. are expertly crafted optical components that excel in beam deviation and retro-reflection applications. These prisms offer a significant advantage over plane mirrors due to their ease of mounting and alignment, ensuring precision in optical setups. The design of the right angle prism allows for high throughput, particularly when the hypotenuse is employed in total internal reflection (TIR) mode. This is further enhanced by anti-reflection coatings on the entrance and exit surfaces, facilitating a 90° angle reflection for incident beams and resulting in inverted images.

For applications requiring external reflection, the hypotenuse of the prism can be coated with either a metal or dielectric high reflectance coating. This versatility makes right angle prisms an ideal choice for retro-reflection tasks. When a beam enters perpendicularly to the hypotenuse, it is reflected by the prism's legs and exits parallel to its original path. In situations where internal reflection is desired but field angle requirements exceed TIR limits, or if environmental conditions prevent maintaining a clean hypotenuse for TIR, a reflective coating can be applied to ensure optimal performance.

Rocky Mountain Instrument Co. is committed to providing high-quality optical solutions, leveraging a collaborative approach with customers to address even the most technically demanding requirements. By engaging with clients early in the development process, RMI transitions prototype concepts into efficient, manufacturable solutions, ensuring that each product meets the highest standards of precision and reliability.
