Product Name: Optical N-Bk7 Glass Roof Prism for Optical Instrument Model NO.: PRP005 Coating: Customized Customized: Customized Certification: RoHS, ISO9001 Lenses Color: Clear Material: Optical Glass Shape: Roof Prism Transmittance: >95% Type: Customized Usage: Customized Dimension: 17.89mm Angle: 90 Degrees Surface Quality: 60-40 Symmetry: 0.15 Trademark: N/A Transport Package: as Requested Specification: RoHS Origin: Jilin, China HS Code: 90019090 Product Description >> Product Description Amici prism,also called roof prism,itis areflectiveoptical prismcontaining asection where two faces meet at a90° angle.These two 90° faces resemble the roof of abuilding, giving this prism type its name.Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet. Characteristic for aroof prism is that the beam is split in half, with one half of the beam hitting first one face then the other face, while it is invert for the other half of the beam.Therefore aroof prism can be used only with some distance to focal planes, or the "edge" of the roof would introduce slight distortions.Furthermore the angle between the two faces has to be very close to 90°, or image quality would be degraded.+ Picture show of our amici prism/ roof prism+ Drawings of prism we manufacture+ Precision of specification we can achieveRange of diameterDia.0.7mm-dia.400mmRange of curve radiusR1.5-r∞ etc.Tolerance of diameter+/-0.1, +/-0.01, +/-0.005 etc.Surface accuracyΛ ,1/2λ ,1/4λ ,1/10λ etc.Tolerance of thickness+/-0.1, +/-0.05, +/-0.01 etc.Centration+/-2′,+/-1′ etc.Aperture n5, 1etc.Irregularity δn2, 1, 0.5, 0.2 etc.Surface quality60/40, 40/20, 20/10, 10/5 etc.>> Company Introduction>>Related Products VY Optics could also manufacture and design other optical elements, includingachromatic lens,dome lens,filter,prism,ball lens,cylindrical lens,optical mirrors,spherical lensandrod lens, we can fabricatehigh-precision lensas per your requested.>>FAQQ:Do you provide samples?
