Bandpass type filter glasses are useful for enhancing the signal-to-noise ratio of illumination systems, transmit a broad band of energy while blocking the shorter and longer wavelengths. As with all of Anover'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.
