Dove prism is a kind of reflection prism used for image reflection.Dove prisms are formed by truncated rectangular prisms.A beam of light enters one of the slanted faces of the prism, fully reflects from inside the longest (bottom) face, and then exits from the opposite slanted face.The image through the prism is flipped, and since only one reflection occurs, the handedness of the image is reversed.Dove prisms have an interesting property that when they rotate along the vertical axis, the transmitted image rotates twice as fast as the prism.It is very important that applications use parallel or collimating beams and keep the large square reflector very clean.Another application is as an inverse.

Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. The high-precision window is made of BK7 optical glass and UV fused quartz, the fused silica quartz window plate is suitable for high power laser that needs good thermal stability, and the window made of N-BK7 material is cheaper, which is suitable for laser applications that pay more attention to cost.Both fused quartz and N-BK7 laser window plates have precision grades of 1/10 lambda surface flatness and 10-5, 20-10 surface quality to ensure minimal interference to the transmitted beam.Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. we can offer 24 inch zygo flatness reports, full CA 600mm windows.

United photonics technology Glan Taylor Polarizer Glan Laser Polarizers High Transmission Glan Laser Polarizers Glan Thompson Polarizers Broadband Glan Thompson Polarizer( 200-3300nm) Wollaston Polarizers Rochon Polarizers Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces. The polarized field F1 and F2 of these is shown in the plot below. Features: Air-spaced Close to Brewster's Angle Cutting High Polarization Purity Short Length Suitable for low to medium power online_ordering where the rejected beam is not required Specifications: Material:a -BBO, Calcite or YVO4 Wavelength Range:a -BBO: 200-3500 nm, Calcite: 350-2300 nm, YVO4: 400-5000 nm Extinction Ratio:Calcite:
