Multi-wavelength laser modules: 1064 + 445 nm tec heatsink Tested for 48-72 hour nonstop

Tested for 48-72 hour nonstop operation

This is how the spot looks when focusing with a single plano-convex lens with F = 25 mm:

Adjustable laser beam diameter 20-200 um (microns) and adjustable focal range (the range from the laser to a surface)

For optical experiments like refraction

Cooling: 2 TEC-12706
