Other properties
  • Same working length for two magnifications 1x and 2x.
  • Optical design with diffraction-limited quality.
  • Change of the laser spot size by moving the inner lens without changing the entire lens to avoid dust on the optics when using.
  • At intermediate magnification values - some, up to 15 mm, change in the working length.
  • Compensation of thermal focus shift is possible by moving the movable lens.
  • Other combinations of working magnifications are available upon request.
  • Mechanical design is adaptable.
  • Specifications are subject to change upon request.
