To improve the quality of light in a new generation of demanding lighting applications, Nichia has developed a family of white LEDs named OptisolisTM which offers ultra-high Colour Rendering Index (CRI) values.

The light output from the Optisolis range of LEDs has the closest possible match to that of natural light. The Optisolis LEDs are optimised for the general lighting market.

The outstanding performance of the new LEDs is the result of the application of proprietary Nichia blue chip and phosphor technology meaning that Optisolis delivers guaranteed minimum CRI values across the entire spectrum.

Lighting equipment manufacturers can use Optisolis LEDs to enable artificial lighting schemes in which all colours appear almost exactly as they would under the light of a reference light source. In addition, since ultraviolet emissions are almost non-existent in the Optisolis spectrum, degradation caused by irradiation is dramatically reduced compared to the damage caused by the UV emissions from other commercially available LEDs.

The Optisolis family consists of two series, the NF2W757G-F1 and NF2L757G-F1. Both series are housed in a 3mm x 3mm x 0.65mm package.
