2. Wavelength Dependent Loss of VIS ND Filters
The following diagram shows the measured wavelength dependent loss of all four
ND filters supplied with the BC106-VIS Camera Beam Profiler.
As seen, the ND filters keep their nominal loss values only coarsely within a limited
wavelength range in the visible. Large deviations are outside this range will require
a User_Power_Correction .
3. Wavelength Dependent Reflectance of AR Coating on UV ND Filters
This diagram shows the typical quality of the supplied reflective ND Filters for the UV
wavelength range.
