  • Focal length from 75mm to over 2,122mm

  • Covering field sizes from 50mm to 1,500mm square

  • Extends over many engraving, marking and cutting applications

  • Designed to be positioned at the same location relative to the scanning mirrors, so are directly replaceable with another focal length

  • Available as mounted
