SGJ Optical Lens System glass spherical convex, concave and biconvex projection lens for optical system for DLP light engine by BK7 , K9 , quartz and crystal
1. Material: BK7 , K9 , quartz , germanium , silicon , zinc selenide and other optical glass
2. Size: Diameter 5-diameter 190mm ( according to customer needs )
3. Dimension error: + 0.0 / -0 Imm
4. Center thickness error: = 0 . Imm
5. Focal length error: = 100Surface accuracy : 3 ( 0.5 )
6. Finish: 40 / 20Chamfe : According to customer need
7. Coating: According to customer needs
Each lens product requires the customer to provide diameter Dia ( mm ) , focal length EFL ( mm ) , radius RI ( mm )center thickness Tc ( mm ) , side thickness Te ( mm ) before you can quote and find inventory. Lenses can be widely used in various fields such as security , automotive , digital cameras , lasers , optical instrumentsetc . With the continuous development of the market , lens technoso more and more widis made according to the law of light refraction . The lens is an optical element made of transparent material ( such asglass , crystal , etc . ) The lens is a refracting mirror , and its refractive surface is two spherical surfaces ( part of thespherical surface ) , or a spherical surface ( part of the spherical surface ) and a flat transparent body . The images itcreates have real and virtuall images. Plano-convex lenses have a convex surface and a flat surface , with a positive focal length , and are usually used forrelated applications such as beam reduction , focal length reduction or image enlargement . In order to reduce sphericaaberration , the plano-convex lens is used to collimate the light beam to focus , the beam should be incident on thecurved surface of the lens ; when it is used to collimate the point light source , the light beam is incident on the planePlano-convex lenses focus light into a point . Commonly used for aiming and focusing of monochromatic lightsources . When in use . face the convex surface towards the incident light. Application areas: security , vehicle , digital camera , laser , optical instruments
SGJ can produce: plano-convex lenses , plano-concave lenses , biconvex lenses , biconcave lensesmeniscus lenses , cemented lenses , cylindrical lenses , etc , with nearly ten years of optical product processingexperience and a complete prism lens processing production line . Anti-reflection coating can be applied to reduce thereflection on the lens surface according to customer requirements . This can reduce the loss of light energy and makethe imaging clearer. Generally , in order to protect the lens or the instrument from the weather and the environment , a flat protective glass is placed in front of the lens or around the instrument . A drop The antireflection glass produced by photoelectricity has the advantages of large size , scratch resistance , smooth edges , high surface accuracy and no ghosting. According to customers requirements , combine eachwavelong light source can be divided into single-point antireflection and wideband antireflection , 380-1100nm wideband antireflction , is to protect various windows of optical instruments and optical lensesprovide the highest definition and high transmission effect . Our products have special effects such as waterproof , anti-drop , anti-shock , anti-fingerprint , anti-oil stain , high light transmission and so on.
