NYTL/NYDL (YAG Laser Focusing Lenses)
  • NYTL/NYDL (YAG Laser Focusing Lenses)
  • YAG laser focusing lenses are air spaced triplets or doublets for YAG fundamentals.
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.
