    Best lens setup for smallest most perfect focus dot possible at around 300mm distance

    Hi, I am busy designing a few prototypes of 3d printers based on laser stereolithography. I have experience with setting up a 445nm 0.7W laser for cnc engraving, but this time the purpose is to be able to focus a 405nm (445nm is multipoint so unusable) to as small as possible dot as possible...

    looking for: 405nm laser for burning very very smal spots at +- 1meter (3 to 4 foot)

    Hi, First of all I'm not a newbie to lasers, since I work with them for about 3 years now. In the beginning I worked with fibre-coupled 808nm diodes of 1 watt, but I stopped those because I prefer to SEE something instead of visible IR. Currently I use a 700mW 445nm blue laser on my portal...

    Beam combiners for 445nm ?

    Hi, 1) Does anyone know where I could find beam combiner (those glass-like cubes) to combine 2 445nm beams into one? 2) Also, since the 2 beams come from a module, the modules focus on their lenses, but should I then mount another lens behind the beam combiner to create the focal point again...
