LP415 filters reflect the full UV spectrum, and will not solarize over time, effectively blocking most of the light emitted by 395nm and shorter wavelength UV LEDs.  These filters also act as a protection window for lenses and are well suited for color imaging applications. The substrate material is Borofloat®, meaning LP415 can tolerate temperatures up to 500°C and is shock resistant. For more demanding (non-imaging) applications, LP415 is also available from stock on drawn fused quartz sheet material (≤1000°C).
