Single chip encapsulation lens
Single chip encapsulation is the basic unit of UV LED, and it is also the most widely used package type. NOVAXIL™ silica lens provides a variety of view angles, which meet the mainstream LED package specifications. NOVAXIL™ silica lens could be balanced between UV illuminance and module uniformity according to application requirements. To achieve a balanced configuration, if you are looking for a higher output solution, please refer to the four-chip package lens.
For current mainstream UV LED packages, the NOVAXIL™ single chip encapsulation lens series can perfectly match standard UV LED types such as 3535 / 3838 / 3939 / 4040 / 5050, offering a variety of view angles from 30 degrees to 60 degrees. If you have more precise requirements on the optical performance, we also provide lens design evaluation and customization services.
