ULO Optics F-theta Scanner Lenses

ULO Optics' ZnSe singlet scanning lenses, the TSL series, are optimised to minimise the off-axis aberrations.

   ● best compromise for all aberrations, field flatness and F-theta error using a single-

      element, spherical surface lens
   ● for beams up to 15mm full diameter
   ● focal length from 75mm to over 2122 mm
   ● covering field sizes from 50mm to 1500mm square
   ● use 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
   ● also available mounted
   ● available with a number of different coatings for different wavelengths

Spot diameter is determined from optical computation and are not measured values from marking or engraving. The width of an engraved line is affected by laser power, material, scan speed, etc and is normally less than the values listed here.

Should smaller spot sizes be required for the same focusing lens, we recommend the use of multi-element lenses, or of our larger diamter singlets (Please call for more info on the larger diameter singlets).
