Looking for some shortwave UV LEDs that are reasonably priced. I'm interested in LEDs around 250nm and 365nm. From what I've seen the 250nm LEDs are extremely expensive (400€ a piece!), but 365nm are supposed to be fairly cheap these days. However, I'm having some difficulty in finding them. Roithner Lasertechnik has 3mW 370nm LEDs for around 3€ a piece which is OK, but considering their prices on lasers I get the feeling they can be had for less elsewhere.
Any ideas?
