I'm trying to develop a device to burn a glass slide surface with a special pattern of UV light (between 300 nm and 360 nm) in a 5 cm square surface.
I've read several threads asking questions about LCD printers and their way of functioning but I am not entirely sure how they work. So far I have found two methods that explain LCD printers:
The LCD screen emits light in UV spectrum that causes the resin to cure. I don't believe there are any LCD screens that can emit at 360 nm.
Initially there's a UV light bulb 'behind' the LCD screen which is translucent when off. The pattern is drawn in the LCD screen interfering with UV light's path drawing the image in the plate.
If option two is the right one, do you know any devices (uv light and lcd screen) to develop what I want within the 360 nm wavelength?
Alternatively, can a DLP projector to emit UV light (by adding a UV light bulb)? Would it still need to be cured?
