Negative Filter

 

The filter is a kind of optical elements which to make a specific wavelength of light to pass through, and the other wavelength of light reflection or attenuation. The advantages of the filter having the high transmittance of the peak value, a flat pass band spectrum in a wide wavelength range with excellent cutoff, and the temperature stability is better.
Negative filters can reduce the certain laser wavelengths such as 488nm and 561nm, not only has protective effects on the eyes, but can identify the spectral characteristics of different colors objects more clearly. The negative filter has a small half bandwidth and the accurate wavelength positioning.
