Hi all,
I'm trying to build an SLA DLP printer that prints at 405nm UV wavelength and I'm thinking of purchasing this optical engine (projector).

What is a good working distance for SLA? 92mm, 700mm, or 184mm? My setup will have the projector pointed at a 45 degree mirror.
The website says the lens come with coatings (UV or visible), if I want to print with UV I would pick a UV coating right? Or will a UV coating filter out the UV that I'm emitting?
Thank you for your time.
