The selection of filter

Must have some understanding of the filter before the selection filter, filter products mainly by the spectral bands, the spectral characteristics of the form, application characteristics classification.

A filter selection

Methods / procedures

1 Spectral bands: UV visible light filter, filter, infrared filter, filter; (such as on the spectrum is not clear, can reference spectra are as follows:)

2 Spectral characteristics: band pass filter, cut-off filter, filter, neutral filter, reflection filter;

3 The bandpass type that is selected by the band of light, passband optical cut-off. For example, our infrared band pass filter.

4 Short pass type is shorter than the selected wavelength light through, longer than the wavelength of the light off. For example, infrared cut-off filter.

5 Long wave pass type that is longer than the selected wavelength light through, shorter than the wavelength of the light off. For example, IR filter, IPL filters.
