Optical Glass Mirror is an object with a surface that has high reflection. It is smooth enough to form an image. The most familiar type of mirror is the plane mirror, which has a flat surface. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected image. Mirrors are used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery. Most mirrors are designed for visible light; however, mirrors designed for other types of waves or other wavelengths of electromagnetic radiation are also used, especially in non- optical instruments.

Corner Cube prism has three mutually perpendicular surfaces and a hypotenuse face.  It operates on the principle of total internal reflection(TIR).  A beam entering the effective aperture is reflected by the three roof surfaces and emerges from the entrance/exit surface parallel to itself. This property is independent of direction of the retro-reflector, within acceptance angle limitations.  For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces can not be kept sufficiently clean for TIR, a metal or dielectric coating can be applied to the reflecting surfaces.  Specifications: Attribute Specification Material: BK7 Glass Dimension Tolerance: +0.0/-0.2mm Deviation: 180°±3 arc second Flatness: -λ/4 on big surface, λ /10 on other surfaces Clear Aperture: >80% Surface Quality: 60/40（General),10/5(High Precision) Bevel: 0.1-0.5 Coating: Uncoated
