Do you have more details on that g7 lens ?

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...

I think DTR is meaning 405nm diode @ <500mA 455nm can go lot higher

What amount of mW do you expect aproximatly from a 405nm diode with G2 lens @ 420mA ?

To get a good focus I'm going to set the flens on a stepper motor with extreme reduction. This would allow me to focus 1 full turn of the lens in maybe 3200 steps, so I guess that would suffice :) The laser seems capable so now need to find info about the driver. These p3 flexmods could be the...

ok thank you for your answer. The question is however not completely solved (or at least I am not 100% sure yet :) With my current 445nm laser at aprox 700mW I can focus on a spot less then 1 inch away from my module and I can burn spots of 0.2mm size in wood or paper (laser is therefore only...

I'm interested in a 405nm inside module + 405-G-2 Glas lens. Just few questions 1) What power do you think will come out when you provide aprox 450mA to it? 2) Can these be focussed to have a very !VERY! small burning point at aproximately 3 or 4 foot distance? (I certainly cannot with my...

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...

Hi and thanks for reply. So if I understand right, when using such a PBS, I would have to set both modules to focus on infinity (so a parallel beam like real lasers should be according to most people) and then they pass through the PBS, but now there is something I don't understand. Since the...

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...
