New Highly Efficient UV Optics for the UV-C Range from Asahi Rubber

The Japanese optics manufacturer Asahi Rubber recently introduced new UV optics especially for the UV-C range (280 nm). The silicone lenses named AL-10M-DUV280 (for LEDs of a size of 3.5 x 3.5 mm) and AL-20M-DUV280 (for LEDs of a size of 6.8 x 6.8 mm) were measured with the UV-C LEDs of the type NCSU334B from Nichia and subjected to an endurance test of 15000 hours, whereby hardly any loss of brightness and no damage could be detected. This underlines the high quality of the optics, whose light transmission is 90%.

The UV lenses AL-10M-DUV280 and AL-20M-DUV280 have a radiation angle of 10 and 20 degrees respectively, other radiation angles are conceivable. The Japanese company is currently testing whether the good test results can also be reproduced at shorter wavelengths. The UV optics from Asahi Rubber can be used in various applications such as water treatment, air purification, sterilisation of medical instruments and other areas.

The highly efficient lenses are distributed in Europe only by the Swabian LED expert Lumitronix.
