OPTICAL FILTER
Inventory Levels
These are finished units on the shelf, not a catalog — each row is one physical filter, with its own measured performance and test report.
These are finished units on the shelf, not a catalog. Each row is one physical filter that has been assembled, measured and set aside. The figures shown are that unit’s own measured performance — not a specification band — and the test report at the end of each row belongs to it alone.

If one of these matches your operating point, it can ship without waiting for a build. If none does, the same cavity is available anywhere from 700 to 2500 nm as a made-to-order unit; the standard references are listed on the filter models page.
Tell us which reference you need and we will confirm it is still available.
