Primelite UV-LED Performance Optics – the Key to Superb Exposure Results
It takes powerful light sources and painstakingly matched optics to produce superior results in challenging UV exposure scenarios. Given the wide of range use cases, individual requirements can be very specific. For example, high-speed curing in automotive manufacturing and medical engineering is not all the same as precision UV exposure of wafers in semiconductor fabs.
Our UV-LED Performance Optics shine in all these manufacturing environments. Primelite’s innovative solutions deliver utmost efficiency at the right price, while achieving precisely the collimation and uniformity properties you need. Our standard optics portfolio covers many exposure scenarios, but custom UV-LED optics is very much a part of our daily business.
UV-LED Performance Optics Highlights:
Generally speaking, LEDs are light sources with a broad radiation pattern (high NA). Our lens systems are a remarkably affordable add-on to reduce divergence or even focus radiation for maximum intensity. Our LED Performance Optics are also an excellent choice if you want to improve the uniformity of the exposure field, which can be hexagonal or square.
Primelite’s standard LED Performance Optics are exceedingly compact additions to our Advanced Light Engines. But we can think big, too, as our tailor-made precision exposure setups for large substrates would attest.
Primelite’s LED Performance Optics exclusively use UV-grade material.
