COLORED FILTER GLASS - LONG PASS TYPE
Long pass type filter glasses are useful for order sorting applications. They block the shorter wavelengths while transmitting the longer wavelengths. As with all of Andover's filter glasses, custom sizes are available upon request, and can also be mounted in threaded rings (click for sizes).
All graphs show internal transmittance at the standard 3mm thickness. We can polish to other thicknesses upon request.
Our in-house fabrication and polishing capabilities enable us to provide a quick turnaround on custom parts.
