Optical Instruments

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.

Aspheric lens is an optical element which have a complex radius of curve, at least one surface is not spherical. The radius of curve is gradually change from center to edge, there have a specified formular of aspheric lens which designed by customers. Compare with spherical lens, aspheric lens reduces or minimizes spherical aberrations, for example, astigmatism, field curvature, and distortion.

Fused Silica Window is usually used a protective window for an electronic sensor or a detector of the external environment, which is used to separate the environment on both sides, such as separating the inside and outside of instrument are isolated from each other, so as to protect the internal devices, it does not change the magnification of the system.

Sapphire Step window have a wide transmission band and have good light transmission from UV to IR (0.15-5.5um) with low bubble and inclusion content, so it’s widely used in components, infrared devices, high intensity laser lens material and dome materials, it has high sound speed, high temperature resistance, corrosion resistance, high hardness, high light transmission, high melting point(2045℃) and other characteristic , it’s a very hard to material to processing. Sapphire windows can resistance of higher temperatures, high pressure, strong vacuum or corrosive environments, because of these features sapphire windows can withstand harsh environmental conditions and provide good performance and reliability, therefore it can be used to make optical components, night vision cameras and other instruments, it can be seen that it has many advantages  Substrate Sapphire Single Crystal Size 5-420mm Thickness 0.1-20mm as request Dimension Tolerance +/-0.01~+/-0.1mm Shape circular, rectangular, wedged, pin, window with hole, irregular shape, customized chipping <0.1mm Bevel <0.2*45degree Parallelism <3arc min Surfce Quality 40/20 Coating as request
