CI Systems OPTISHOP - MTF Station

Product Code:
Optishop
Manufacturer: CI Systems

A few of the OPTISHOP advantages with the Video MTF configuration are:

  • Simultaneously tangential & sagittal MTF measurement
  • Measuring a system with a short and negative back focal length
  • Real-time alignment of zoom optics

CI Systems offers a cost effective and modular optical test bench to measure the Modulation Transfer Function (MTF) and transmission of optical components in the visible, SWIR, MWIR and LWIR spectral ranges. The OptiShop allows for video and slit scanning MTF tests.

Video capture MTF allows for real-time measurement of optical components as well as systems. It is used when high throughput test rate is required. CI Systems has developed diffraction limited, chromatic corrected, optical relay (objective) for the SWIR, MWIR and LWIR MTF tests. It enables adequate sampling and low aliasing. Therefore, OPTISHOP is not limited to high resolution sensors but can be used to test a wide range of FLIR systems.

Supported tests:

Lens Measurement:

  • MTF measurement of low resolution systems.
  • MTF, through Focus MTF
  • EFL
  • BFL
  • Relative Distortion
  • Astigmatism
  • Depth of Focus
  • Field curvature
  • LOS (Zoom Lenses)
  • Mechanical Boresight
  • Distortion

FLIR camera measurements:

  • MRTD (objective & subjective)
  • NETD
  • MTF
  • SiTF
  • Uniformity
