Affordable 3W UV LEDs

Posted on February 8, 2012
I am currently building an UV exposure unit, which works with LEDs instead of tubes (much better efficiency and lifetime). It seems really hard to find affordable high power UV LEDs.
Also I needed LEDs with a wavelength of 400-410nm instead of the 410-420nm, which you can usually get.
Therefore I contacted Future Leds and they made me a really good offer, though they had to make them especially for my specifications:

More glass!

Received the beam splitter for the Advanced Holosight porject today:

They are used to mix the beam of the display and surrounding light to create that holographic effect.
I got them made by Prinz Optics. Very high precision, good quality and fast process time. Really pleased with their service.

Just finished a quick GUI for the Nokia6100 LCD:

I plan using this display on my Advanced Holosight project.

Infrared Strobe Light

When it comes to using night vision devices you mostly can only afford old Russian ones. However they are still good enough to detect other people at great ranges. Still identification can be a problem.
Therefore I swiftly built an IR strobe light and integrated it into a boonie hat. Now you can see each other at almost any range immediately.
