The focusing principle of SCULPFUN laser module
20mm
Focusing principle:
1、The focal length of the SCULPFUN
laser module is fixed and cannot be
changed .
2、The specific position of the laser
focus is 20mm directly below the
edge of the aluminum alloy shell of
the laser module.
3、We provide a 20mm measuring
aluminum column to help find the
laser focus.
4、When the laser is focused on the
surface of the engraved object, it will
exert its maximum engraving effect.
