Description
Corner Cube Retro-Reflectors from Rocky Mountain Instrument Co. are precision optical components designed to reflect light back to its source. Utilizing the principle of total internal reflection (TIR), these retro-reflectors ensure that a beam entering the aperture is reflected by the three roof surfaces and exits parallel to the incoming beam. This unique property is maintained regardless of the orientation of the retro-reflector, provided it remains within its acceptance angle limitations.
In scenarios where the acceptance angle for TIR is exceeded or when maintaining clean reflecting surfaces is challenging, a metal or dielectric coating can be applied to the surfaces to enhance performance. This adaptability makes Corner Cube Retro-Reflectors a versatile choice for various optical applications, ensuring consistent and reliable performance.
Rocky Mountain Instrument Co. prides itself on a collaborative approach, working closely with clients from the early stages of development to deliver efficient and manufacturable solutions. This commitment to customer satisfaction and technical excellence positions RMI as a leader in the optical components industry.
