###### **Optimize UV LED Arrays For Efficiency and Performance**

**![Rod Optic Diagram](https://go.koppglass.com/hs-fs/hubfs/rod%20diagram%20flat.png?width=263&name=rod%20diagram%20flat.png)![TIR Optic Diagram](https://go.koppglass.com/hs-fs/hubfs/tir%20diagram%20flat-1.png?width=263&name=tir%20diagram%20flat-1.png)**

At the 2018 RadTech UV+EB Technology Conference, we presented a case study that demonstrates a method of optimizing UV curing systems for performance—using UV transmitting molded borosilicate [Total Internal Reflection (TIR) optics](http://www.koppglass.com/UVLED/).

The results of the case study conclude that TIR optics are more efficient at capturing stray rays of light and increasing peak irradiance than a commonly used fused quartz rod solution.

**This case study will help you understand:**

- How and why UV rays miss the target surface
- The excess wattage needed for UV LED arrays with quartz rod optics
- The  performance difference between TIR optics and fused quartz rods

**Designing more efficient UV curing systems will translate to cost savings that can increase over time. By using TIR optics, UV LED arrays can realize their fullest potential.**
