Specification

▶The filter transmittance wavelength characteristics are on the surface and the backside of the filter. It happens to have multi-filter with different coating characteristics pilling together and mounted into a optics frame.

▶If the light incident angle is other than 0 degrees, the transmittance characteristics may be changed. In the normal situation, when the incident angle changes, the wavelength may shift to the longwavelength side.

▶An arrow indicating the light incident direction of the BP filter and the BA filter is different.

▶The filters are made for use in high temperature environment but for a usage of high power exposure UV lamp, the stability and the efficiency of the filters are not guaranteed.
