Filters for extending the blocking of our Continuously Variable Filters
Homogeneous Blocking Filters
Delta Optical Thin Film has created a range of Homogeneous Blocking Filters, designed to enhance the blocking of some of our Continuous Variable Filters. These filters offer high transmission in a wide wavelength range while blocking other wavelengths in the complete silicon sensor wavelength range (300 – 1100 nm). The filters are designed to be switched in and out of the beam at certain wavelengths
