Hobbite ® Penta Prisms Feature Penta prism can deviate an incident beam without inverting or reversing to 90o. The deviation angle of 90o is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Rangefinding and Optical Tooling Application Projection Optics Systems Imaging Optics Systems Optical Measurement Systems Optical Display Systems Specification Material: BK7 Grade A optical glass Dimension Tolerance: +0,-0.2mm Flatness: A/4 at 632.8 nm Surface Quality: 60-40 scratch and dig Clear Aperture: >80% Bevel: 0.2 mm to 0.5 mm x 45o Reflectivity: R > 95% ( for design wavelength) per face Email: [email protected] Tel:+86-755-2372 7820 Fax: +86-755-2302 3823 www.hobbite.net Address:2F, Guohuitong Business Center, BaoAn District, ShenZhen City, GuangDong Province, PRC.
