LED specialist Innovations in Optics says that it now offers a range of light engines that can photocure adhesives and coatings.

LumiBright UV-LED feature UV die arrays bonded on MCPCB substrates that enhance thermal performance for high current density operation. The specialized primary optic is a non-imaging concentrator made from fused silica, making it suitable for for high power UV flux. With active cooling, the model 2400B-405 model can emit greater than 20 watts from a 7.5 mm diameter clear aperture with a 0.66 numerical aperture (NA), while model 2400B-505 light engine can produce over 10 watts of radiant flux from a 5 mm diameter clear aperture with 0.60 NA. LumiBright UV-LED Light Engines are available with wavelengths centered near 365 nm, 385 nm, 395 nm, and 405 nm.  

For spot curing applications, the light engines can couple to liquid light guides for the ultraviolet, the company says.
