Optical Dove prism

glass

• Image inversion and rotation • Optimized for 400-700 nm Dove Prisms are a truncated form of right angle prism. They use total internal reflection to produce an inverted image which emerges without any beam deviation. The main application for these prisms are as image rotators. Rotating the prism about an optical axis results in the image rotating at double the angular velocity of the prism. It is very important that the incident beam is collimated for optimal performance. In addition the large reflecting face must be kept very clean. Ealing Dove Prisms are broadband antireflection coated for 400-700 nm on the entrance and exit faces for maximum transmission.
