Lenses

Optical prism is an optical element which accordingly incident light and outgoing light to make turning ray of light. In the optical path, the prism can making the light offset and changing the direction of the image and also has the function of changing the angle of outgoing and incident light, such as deflection 90° or 180°.Prim widely used on laser research, laser optical systems, optical image, machine vision and other fields and products. Right Angle prism also called Right Angle Bending Prism, because it can turn light 90° by internal reflection of hypotenuse, or turn light 180° through two right angle prism surfaces, accordinlgy customers demand. Many different coatings applied to these prisms, some common types are Anti- reflection coating on two legs, Aluminum protected coated on hypotenuse by black sealing paint to ensure grazing incidence reflection and two angle surface make VIS AR or NIR AR, accordingly customers demand. These prims are suitable for optical delay lines and for high power use.

An Aspheric Cylindrical Lens is a specialized optical component designed to focus or shape light along a single axis, typically used in applications requiring precise beam shaping or correction of optical aberrations. Unlike traditional spherical lenses, aspheric cylindrical lenses have a complex surface profile that helps minimize distortions like spherical aberration.

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.
