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 … Continued
LP390 filters are absorptive filters used to block ultraviolet (UV) light while allowing high (>90%) visible and near-IR light transmission. Most silicon camera sensors have some sensitivity in the UV spectrum. In some color cameras this light can typically be recorded as if it is blue light, resulting in an exaggerated bluish tint. These filters … Continued
Durable, broadband, multilayer hard coated LP340 filters are economical glass protective windows that help eliminate reflected glare, thus improving contrast and brightness while protecting far more costly lenses, cameras and lighting. Custom shapes and sizes can be quickly fabricated in 1mm or 2.25mm thickness.
LP330 Protective Windows are the lowest cost alternative when it comes to dust covers or protection of optical components. No anti-reflection coatings are provided, however parallelism and surface quality are excellent. A slight reduction in infrared and deep red transmission may also be associated with the LP330.
Low scatter/absorption combined with excellent strength; thermal, mechanical and solar properties similar to Pyrex make LP285 filters an excellent protective window for imaging applications between 385-1100nm.
