Visible and Near IR Interference Filters
The visible range filters cover 50nm increments from 350 to 800 nm with bandwidths of either 10nm or 40nm. All interference filters are mounted in a metal ring and engraved with the center wavelength and bandwidth.
All our interference filters are supplied with an individual spectrophotometer trace.
