Custom Bandpass Filters by Andover Corporation

To select a custom bandpass filter:

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