Blue glass filters (IEC series) are characterized by high transmittance from blue to green, and absorption from near-infrared to infrared.
Taking advantage of this, it is installed in smartphones, digital cameras, security cameras, automobile cameras, etc., and contributes to color correction of image sensors.
Image sensor, laser protection
Blue filter <IEB, IVB series>IEB, IVB are UV blue transmitting filter (blue glass filter) designed to have highest transmittance from UV to blue range.
Medical equipment, video equipment
Green filter <IVG series>This is a bandpass filter with peak transmittance at green light, used when you want the highest transmittance at a specific wavelength. It is designed to have the highest transmittance near the center wavelength while keep the unnecessary range (below 400nm, 700-1000nm) as low as possible.
