Properties of the ASA COLOR UV Lens

Our ASA COLOR UV Lens is made of a transparent silicone material that provides an extremely high transmittance in the near UV and blue spectrum compared to other materials. The silicone material gives the ASA COLOR UV Lens high resistance against heat, weather, UV, and IR; these properties allow our lens to excel in high stress environments. Unlike thermoplastic lenses, the ASA COLOR UV Lens does not yellow with extended use. Our lenses are lead free reflow tolerant and can be mounted directly onto the LED. Focus the intensity of the irradiation to increase the efficiency of your UV LEDs.

Standard Lenses

We offer standard lenses for the following UV LED Packages:
-Nichia 033/034 Series (8°, 30°)
-Nichia 233 Series (22°)** NEW
-Nichia 275 Series (10°, 30°)
-Nichia 276 Series (8°)** NEW

**The angles for the 233 & 276 Series are estimates. We are in the process of aquiring detailed data for the new lenses. Detailed information will be posted as it becomes available.
