Specification

▶The filters characteristic depends on the angle of incident. If the angle of the light axis inclines, the center wavelength switch to short-wavelength side and the transmittance may decrease too. More the selected spectrum width is precise more the inclination tolerance is small. Make sure that the incident angle is set at 0 degree for an efficient experiment.

▶The filters usage temperature of environment is set at 23℃ (Celsius), more the temperature is high more the center wavelength switch to the long-wavelength side.

▶Therefore a high precision set up is required for obtaining an efficient experiment each filter thickness is different.

▶Interference filters are heat absorptive, therefore they are not fit to use with high power laser and high energy pulsed laser.
