Adroit Materials SBIR Phase I Award, June 2019

The objective of this proposal is to develop a high power flashlight emitting broadband ultraviolet light for missile signature simulation. This will be achieved by growing large area light emitting diodes (LED) on single crystalline AlN substrate, which increases power density by more than an order of magnitude compared to conventional UV LEDs grown on sapphire substrates. In combination with an appropriate heat sink and beam collimation system we will demonstrate and deliver a prototype UV flashlight emitting 500 mW light at around 280 nm with lifetime exceeding 1000 hrs.
