Comparation with 1875 green laser
1.our 1875 green laser is DPSS laser module, it has dust-proof cover and a little bit water-proof effect. but the 1655 one does not have dust cover and do not have waterproof effect. so that it cannot work on stone sawmill.
2.working temp. of 1875 green laser is 0 C~ 45 C, the 1655 one is -15 C ~ 45 C， if you add heatsink on it, you can prolong the duty cycle as long as you want.
3.1875 green laser module is unfocusable, we had set the fl at 3m, while the 1655 one is focusable, you can rotate the tip of the laser housing and adjust the fl as you like.
