Product Name: N-Bk7 Retroreflector with Coating or Uncoating Model NO.: PRR Coating: Polish Customized: Customized Certification: RoHS, ISO9001 Lenses Color: Clear Material: Optical Glass Shape: Pyramid Transmittance: >95% Type: Retroreflector Usage: Lighting, Medical, Optical, Photography, Industrial Measurement Surface Quality: ?/4 or Better Surface Finish: 60/40 or Better Trademark: Sinocera Transport Package: Carton Specification: Customized Origin: Shanghai, China HS Code: 9001909090 Product Description Solid glass retroreflectors are also known as corner cubes or trihedral prisms. Any ray entering the effective aperture of a retroreflector will be reflected and emerge from the entrance/exit face parallel to itself, but in the opposite direction of propagation. Solid retroreflectors depend upon the principle of total internal reflection and therefore have acceptance angle limitations.An incident beam, filling the effective aperture, is reflected exactly back on itself.Protected-aluminum coatings can be applied to the rear reflecting surfaces to avoid TIR failure from acceptance angle limitations.All antireflection coatings available.Parameter Value Specified and Torlerrance AQLMeterage outcome Length/Diameter (L/D)Customized100%Thickness (T)Customized100%Surface Accuracy (N)N<λ/4AQL1.0Surface Quality (S/D)60/40100%Clear Aperture (CA)>90%center100%Chamfer/Corner ,Protective chamferingAQL1.0Chips≤0.2100%Beam Deviation<20″AQL1.0CoatingRemarks:Inspector:Date:Date:
