Solar Blind Filters
Originally designed for the space program, these unique "very broadband" UV and VUV filters are useful for isolating broad bands of UV or UV-VUV radiation, while rejecting visible light. Acton Research very broadband filters offer broadband transmittance properties, averaging 10-20% over the bands specified. Rejection is approximately 5x10-3 at 500nm.
Model 120-VBB: Care must be taken to avoid contact with the coated surface of this open-faced design, as absorption of the substrate at wavelengths near 120nm typically prohibits covering and edge sealing.
Model 170-VBB: Is manufactured open-faced, however it can be supplied covered and edge sealed to protect the coated surface.
