LED Lens

NOVAXIL - Silica Lenses

Silica lens for UV LED encapsulation, NOVAXIL™ high-purity silica glass, with optimized optical design to ensure the best UV transmittance, LED reliability, and improved optical performance. The unique patented sol-gel process technology of Cristal Materials, on the platform of high purity silica glass, exerts the molding characteristics of liquid molding process, integrates material stability, UV transmittance, and optical control ability, and launches NOVAXIL™ LED encapsulation lens series, the No.1 choice for UV LED encapsulation lens solutions.

Single Chip Encapsulation Lens

Lens for single chip UV LED encapsulations, suitable for 3535 / 5050 package. 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.

Special Lens

Total Internal Reflection Lens (TIR Lens)

The key to the design of the TIR lens lies in the accuracy and surface quality of the total reflection surface, which requires high molding ability. The quality of the reflection surface processing has a direct impact on the efficiency of the LED module. With the flexibility of the sol-gel process, NOVAXIL™ TIR lenses not only meet the design requirements on optical surfaces, but also provide the physical and optical properties of high-purity quartz products. The UV durability of quartz materials is more suitable for matching with high-power UV LEDs use. NOVAXIL™ TIR lenses are available in several design options in different size ranges, and can also be customized according to customer needs. In addition to the more common single-sided design, double-sided TIR design or array TIR lens design can also be achieved. NOVAXIL™ TIR has been used in PCB exposure systems to reduce the angle of focus while taking into account the uniformity required by the exposure system.
