Optical filter, can effectively inhibit higher than CCD or the light wave of cmos image sensor spatial frequency by by cause ripple to disturb, and have
Effect ground inhibits infrared waves, improves colored CCD, cmos image sensor effective resolution and colour reproduction, makes image clearly
And stabilization.Smalt cutoff filter is to add the absorption of itself by being coated with infrared cut coating on smalt surface
To achieve the effect that end infrared waves.Smalt optical filter can be solved in large angle incidence to infrared light wavelength shift,
And image color can be kept softer, natural to avoid the secondary imaging of conventional red colo(u)r filter reflected light.Due to smalt
The reason of material itself, film layer structure and coating process, easily causes Coating Materials chipping, the prior art when cutting smalt
In, the thickness of product is typically smalt thickness+multicoating thickness, and blocked up thickness is caused to cause visible light transmittance rate low,
If thickness is thinned and is reduced to the absorptivity of infrared light again.
