Custom Bandpass Filters
.15 to .8nm bandwidth 2.0nm bandwidth 10nm bandwidth
1.0nm bandwidth 3.0nm bandwidth 20nm bandwidth
1.5nm bandwidth 5.0nm bandwidth 40 to 80nm bandwidth

 

To select a custom bandpass filter:

  1. Find the desired bandwidth
  2. Select the number of cavities within that bandwidth, if applicable
  3. Find the proper wavelength range within that bandwidth
  4. Choose a blocking range (X-ray to 1µ or X-ray to FIR)
  5. Select a standard size
  6. Select the part number that corresponds to your choices to view part detail AND pricing
