Penta Angle Prism are widely used in laser level, Image system, precision system, and optical area. For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled, we can produce high precision penta angle prism,and make coating according to customer's request.

Corner Cube Retroreflectors Corner Cube Prism is also called Retroreflector or Trihedral Prism. In the Corner Cube Prism, three reflecting surfaces are perpendicular to each other, like the side wall of the cube. The input surface is perpendicular to the cube diagonal. Disregarding the angle of incidence, the output beam is parallel to the input one, but it is of opposite direction. Inset of the several corner prisms, for better matching, their entrance-exit surface is often hexagonal. In case of this prism the phenomenon of full internal reflection occurs so it is not necessary, (however it is possible) to put mirror coating on the reflecting faces. Normally the reflection surfaces are Al reflection coating, and then covered with Cu and Black Painting. Specifications: Material: BK7 Glass Dimension Tolerance (mm): 0.2 (General), 0.1 (High Precision) Deviation: 180 3 arc secs Flatness (per 25mm 633nm): 2(General), 10 (High Precision) Clear Aperture: 80% (small size),90%(large size) Surface Quality: 60/40 (General), 10/5 (High Precision) Bevel (mm): 0.1-0.5 Coating on input and output sides: Note for corner cube retroreflector: (1). Besides N-BK7, custom-made corner cube Prisms made of other optical materials are available. (2). Corner Cube Prisms with lower deviation tolerance, such as 1, 30, or 10, are available. (3). Corner Cube Prisms with better surface Quality (better than 40/20 or 20/10) are available. (4). HR or Metal reflection coating(Al, Ag, Cu, etc.) on reflection surfaces is available. (5). AR coating on input/output surface is available upon request. (6).Custom-made non-standard Corner Cube Prisms at any other size are available upon request.
