Cost of lasers

Postby travandcon » Mon Jan 13, 2014 3:43 pm

Can someone tell me the difference between the David shop lasers for €400 http://ssl.david-vision-systems.de/shop ... gory/Laser
and these for €20 http://www.ebay.co.uk/sch/i.html?_odkw= ... w&_sacat=0

The difference is that the cheap ones are laser POINTers with fixed focus whereas the expensive ones are LINE lasers with adjustable focus.

The former project a single point whereas the latter project a line.

Travandcon,
You can give the 100mW 405nm focusable blue line one for 29.99 Pound a try. But its power is extremely high. Take care of your and other peoples eyes! Best you wear eye protecting glasses.

If you like to reduce the output power you can put a polarizer in front of the laser. By turning it you can adjust each light level. From nearly dark to about 95%.

I think its beam quality isn't as good as that of the DAVID line laser.
