摘要： The present disclosure is directed to an optical filter that advantageously approximates sunlight that is both durable and stable for long periods of time when subject to harsh light intensity, thermal and moisture loads of accelerating weathering devices. The optical filter includes a glass having a lead content of between 0.5% and 50% by weight. In some examples, the filter can be constructed to have a thickness of 0.7 mm to 10 mm. In another aspect of the disclosure, the optical filter is part of an optical filter assembly suitable for manipulating spectral power distribution. The optical filter assembly includes a lead glass optical filter having a lead content of between 0.5% and 50% by weight and an ultraviolet transmissive optical filter. In one example, the ultraviolet transmissive optical filter is constructed from quartz glass. The ultraviolet transmissive optical filter can further include an infrared absorbing coating. In still another aspect of the present disclosure, an optical filter constructed from a lead glass has a thickness selected such that illumination passed through the lead glass has a first ratio and a second ratio. The first ratio is a first total irradiance for wavelengths shorter than 290 nm to a second total irradiance for wavelengths between 300 nm to 400 nm, such that the first ratio is less than 2.0×10−6. The second ratio is an irradiance at 310 nm to the second total irradiance, wherein the second ratio is at least 1.2×10−3.
