YAG Laser Focusing Lens 30mm Diameter 50mm Focal Length

NYTL-30-50PY1

YAG laser focusing lenses are air spaced triplets or doublets for YAG wavelengths. The elements are made of crown glass of lower dispersion and flint glass of higher dispersion. These lenses are optimized for spherical aberration and coma. With its spot size designed to be smaller than or equal to the diffraction limited spot size for beams at 1064nm.
◦These lenses are chromatically corrected so that any He-Ne guided beam or visible video monitor beam will remain focused in the same position as the YAG beam. All elements are coated with a laser-resistant narrowband multi-layer anti-reflection for YAG: 1064nm and He-Ne: 633nm.
◦We offer optical protective windows to prevent damage to the lens by absorbing high levels of energy from inadvertent back reflection of the incident beam. These protective windows can be easily installed to the focusing side of the lens.

Guide
  • Please contact our Sales Division for customized products. (Customized on size etc.)
  • Please check the “wavelength characteristic of the focal length data” on “Technical Data” for the focal lengths of each wavelength.
Remark -
Attention
  • Since the focal length and working distance of the lens is calculated at 1064nm, it will change at other wavelengths due to the refractive index of the material shift.
  • The F number of a lens is calculated by f (effective focal length) / De (effective clear aperture). The value represents “Brightness of the lens”. The lower the value, the brighter the lens is.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
