  Introduction:

  Blue glass is a main element of OLPF which is combined by blue glass and quartz plates, is mainly applied in front of CCD and CMOS and can also be used individually to cut off infrared light behind 650nm and reduce the imaging influences of red light on CCD or CMOS. OLPF mainly contains materials of QB50A/QB52/QB54 and other marks.

  IRCF can be applied to mobile phone photographing products, vehicle-mounted products, security monitoring products and other products, and can prevent infrared rays from penetrating visible light to ensure normal shooting, so color cast and ghost images cannot be generated by infrared jamming. IRCF mainly contains materials of QB53/QB54/QB55/QB56/QB58/QB64/QB76 and other marks.

  QB5 series material is high in visible light transmittance, and can reach extremely high definition after special coating treatment, thus realizing images with higher quality. QB6/QB7 series developed on the basis of QB5 series can meet individual requirements of customers. QB6 series material can realize a better infrared inhibition effect while having a good transmission property in visible regions. QB7 series material has higher material strength while ensuring a good infrared inhibition effect.

  Semi-transparent wavelength values corresponding to materials and thickness are shown in the following table:
