First test with uv led in position.
Even without having optimized the light path optics a lot of uv is being projected. This photo was taken in a well lit room, when I took the photo my camera immediately “stopped down” to adjust for the amount of light coming from the projected image. The projected image is all 405nm uv.
I will have details of the projector modifications in upcoming posts.
