Salient Features


The  XENON-SAPPHIRE 3.9/95MM 16K is an Ultra high-resolution, high-speed lens is optimized for the use with 16k line scan sensors. It is broadband coated and can be used in the range of 400 – 1000 nm. The V-mount makes it easy to install and rotate into the “best azimuth” position to provide the highest performance for a wide range of high resolution applications.

The Xenon-Sapphire 3.9/95mm provides three specially marked iris settings:

  • f/3.9 is the maximum opening of the stop and provides maximum brightness. The mechanical vignetting at this f/# is only approximately 10% at the edge of the field. The MTF for 100 lp/mm is very high up to the edge of a 58mm image circle, however at f/3.9 the lens is more sensitive to changes of magnification.
  • f/4.8 shows maximum MTF and practically diffraction limited performance over the whole field. The depth of field is bigger but the lens is still sensitive to magnification changes. At f/4.8 the lens is free of artificial vignetting.
  • f/5.7 produces more diffraction which reduces the MTF slightly but is now extremely homogenous over the entire field.  The lens shows this performance for the complete magnification range from -0.26 < ß < -0.21 and performs well for a magnification range of -0.28 < ß < -0.20 at a 16k performance of 100 lp/mm.

Key Features:

  • for 16k line scan cameras (57.3mm length / pixel sizes 3.5μm)
  • for 12k line scan cameras (62.5mm length / pixel sizes appr. 5μm)
  • High resolution optics 400 – 1000 nm
  • Robust mechanics for industrial environment
  • Vibration insensitive
  • Focus and iris setting lockable
