Cut-off filter product advantage:

1, through the belt and the cut with a very steep transition;

2, cut with a very deep;

3, long pass, short pass and band-pass spectral characteristics can be;

4, pass through the belt is very uniform;

5, independent control of band pass filter edge steepness;

6, the passband and the band have wide free spectral range;

7, accurate and repeatable start and stop wavelength;

8, greatly improve the spectrum of the ripple so that it has a flat gain.

The main optical parameters of the product such as: wavelength positioning accuracy, half wave bandwidth accuracy, waveform coefficient (rectangular degree), peak transmittance and other indicators to achieve the level of international similar products.
