Optical filter manufacturer
The optical filter is the most common type of filter. A qualified optical filter should have a transmission curve that follows a perfect Gaussian function, so it’s easy to determine its filtering effect by measuring the transmittance curve.
The optical filter is a device that transmits light at certain wavelengths while impeding the passage of others. The wavelength that is transmitted by a particular optical filter depends on its optical density and its index of refraction. The filter can be used in colour photography to create colour effects, such as creating black and white images from colour ones by desaturating the colours in the picture.
