Cat’s Eye Retroreflector

The retroreflector is a passive optical system consisting of a secondary mirror placed at the focal point of a primary lens. This retroreflector named cat’s eye retroreflector because it looks like cat eyes, it is made of ZlaF90 and with AR coating on one side and AL coating on the other side. There are currently inventory in our stock, please contact us if there is a demand.

The cat’s-eye retroreflector is a passive optical system consisting of a secondary mirror placed at the focal point of a primary lens. We analyze the cat’s eye using the paraxial ray matrix approach. The position of the equivalent reflecting surface and the angular field of view of a realizable cat’s eye are functions of the radius of curvature of the secondary mirror. The field of view is maximum for a secondary mirror with a concave radius of curvature equal to the focal length of the primary lens. We further derive the general dependence of retroreflection errors on misadjustment of the secondary mirror.
