Products: Solar Blind Filters

Originally designed for the U.S. space program, these unique “very broadband” UV and VUV filters are useful for isolating broad bands of UV or UV-VUV radiation. Our very broadband (VBB) filters offer broadband transmittance properties, averaging 10–20% over the bands specified.
Rejection is approximately 5x10-3 at 500 nm. Care must be taken to avoid contact with the coated surface of this open-faced design, as absorption of the substrate at wavelengths near 120 nm typically prohibits covering and edge sealing. Model 170-VBB is manufactured open-faced but can be supplied covered and edge sealed to protect the coated surface. |
