ATL/NADL (Visible Spectrum Achromats)
  • ATL/NADL (Visible Spectrum Achromats)
  • Visible spectrum achromats are air spaced achromatic triplets or doublets for lasers in the visible spectrum or white light application. The elements are made of crown glass of low dispersion and flint glass of high dispersion.
Attention

▶Since the focal length and working distance of the lens is calculated at 532nm, 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.
