SURPLUS - EDGE FILTERS

UV - VIS - NIR

Andover maintains a stock of high-quality surplus edge filters. These are primarily overruns of custom production lots, and exhibit the same high level of quality as all of our other products. Consequently, this can be a very economical alternative to purchasing a custom bandpass filter. All of these bandpass filters are provided with spectral data scans with exact measurements.

You can also search our entire product line, both surplus and standard, by going to the search page and entering the appropriate criteria. Please contact our sales department for a custom quote if there is something you need that you don't see listed. 

We make every effort to keep the quantities updated, please note that all of these bandpass filters are subject to prior sale.
