• Increased Resolution and Smaller Spot Sizes from 750 - 1100 nm
• Decreased Spherical Aberration for Monochromatic Sources Out to 2 μm
• Broadband AR Coating has < 1% Reflectivity Between 750 - 1550 nm
Our TECHSPEC® Near Infrared Achromatic Lenses are designed to provide the
smallest spot size possible for polychromatic light between 750 and 1100 nm. By
utilizing our NIR doublets instead of standard doublets designed for the visible,
RMS spot diameter can be reduced from 43 μm to 22,5 μm, for example, when
using polychromatic light. Typical applications for these doublets include: CCD
imaging lenses for the near infrared, focusing and expanding of NIR lasers, and
focusing/collimating lenses for fiber optics and NIR LEDs.
