COLORED FILTER GLASS - HEAT ABSORBING
Heat-absorbing filter glasses transmit a broad band of energy while blocking the near IR 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.
