#F2F3F2 LP415 UV Block A/R Protective Window

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).

Useful Range : 415-1100nm
Cut-on Wavelength 50% T : 415nm
Tolerance : +/- 10nm
Peak Transmission : ≥95%
Surface Quality : 40/20

The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter's capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance. Filters 62mm and greater have a surface quality tolerance of 60/40.
