General Introduction:The main raw material of glass lenses is optical glass, which has superior optical properties, good light transmittance and mechanical and chemical properties, constant refractive index and stable physical and chemical properties: secondly, glass lenses have a high refractive index and are often used in lens applications. The highest refractive index is 1.9, and finally, the glass lens surface has high hardness and is more resistant to wear.
Products Name: magnifying glass lens/projector lens/convex lens/Instrumentation Process Lenses
Alias: magnifying glass lens/projector lens/convex lens/Instrumentation Process Lenses
Product Description: The imaging principle of the projector: First, the light passes through the filter to filter out invisible light such as infrared and ultraviolet rays, which have a certain damage to the LCD film. The light is homogenized through two multi-lens lenses, and the conical light produced by the UHP lamp is corrected into a rectangular light that approximates the projected image. A prism between the two mirrors is used to pre-polarize the light, which reduces light loss compared to an asymmetric light box without the prism. In the next step, the light is divided into three primary colors of red, green and blue by the beam splitter and reflected to the corresponding liquid crystal plates respectively. Before reaching the liquid crystal sheet, the light also needs to pass through a convex lens and a polarizer. The function of the convex lens is to concentrate the light, and the polarizer further polarizes the light so that the vibration direction of the light is consistent and can be controlled by the liquid crystal sheet. Finally, the light passes through the liquid crystal sheet and is driven by the circuit board, and the pixels on the liquid crystal sheet are opened and closed in an orderly manner, resulting in an image, and rich colors are produced through the adjustment of each primary color light. The last three rays are finally converged and projected by the lens.
