Optical Low-Pass Filter (OLPF) is a core part in digital cameras, video cameras and the CCTV camera optical system. It can effectively prevent the false color and corrugation of CCD/CMOS image sensor due to the pixel interval, and make the image clearer and more stable.

The Cooling plate is a precision optical component in the optical engine of the projector. It mainly uses the excellent thermal conductivity and high permeability of crystal, and is made by precision processing. It is widely used in LCD, LCOS and other projection systems.

A multi-piece combined filter is the core component of cameras, video cameras, and CCTV optical systems. It is generally composed of one or more pieces of optical grade crystal, wave plate and blue glass. The birefringence characteristics of artificial crystal, infrared cut-off film, anti-reflection film, etc. are used to effectively filter out the moiré fringes caused by high-frequency light waves. The blue glass performs chromatic aberration correction and better restores the true color of the image.

This product is mainly used in smartphone camera imaging system. It uses blue glass block material, slices, grinds, and polishes the polished substrate. After coating (AR+IR), it becomes a blue glass filter (allows visible light to pass through, infrared Optical filter with light cutoff); blue glass IRCF has strong absorption capacity in red and infrared light, and at the same time, the half-value wavelength change is very small when incident at a large angle. The blue glass IRCF cuts off the film and the blue glass absorbs infrared light, which can effectively improve the ghost, stray light and color cast problems during imaging. It is a mainstream accessory for high-pixel mobile phone camera modules.

This product uses special low-alpha-line glass or crystal, sliced, polished and processed into a polished substrate. On the surface of CMOS and CCD photosensitive elements, special glass or optical crystal is used to package to protect the chip. It is mainly used in the packaging of optical sensor devices. .

This product is made of glass or quartz by cutting and polishing process. Typical sizes are 6 inch, 8 inch and etc. It' s widely applied in integrated fabrication of optical components.

This product is used for periscope camera modules or light source emission modules to realize the specific angle of light propagation according to customer needs, solve the contradiction between the long focal length optical design requirements of the telephoto optical system and the precious space structure of consumer electronics, and achieve performance requirements , Unification of size control; products used in smart camera phones

application: polished substrate made of D263t, B270i, K9 and other kinds of glass
