Systems and accessories for display measurement

Instrument Systems has developed several turnkey systems for analyzing the characteristics of displays. Each of these systems is based on a spectroradiometer of the type CAS 140CT or Spectro 320 and the TOP 200 telescopic optical probe.

The various turnkey systems have been optimized for the particular area of application and deliver extremely precise measuring results with a high level of reliability:


Spectrometer type

Area of application

DTS 140

with CCD array

Universal for all kinds of displays and panel graphics


with CCD array

Measurement of night-vision compatibility (NVIS) of displays in conformity with MIL-L-85762A


with photomultiplier

Maximum measurement sensitivity and dynamic range for NVIS measurements at 0.01 fL


Spectrometer type

Area of application

DTS 400

Manual positioner

Multifunctional rack for the manual positioning of test sample and measuring device

DTS 500

Automatic positioning system

Complete 5-axis positioning system with stepper motor control

All spectroradiometers can also be operated with the DTS 500 5-axis positioning system and the DTS 400 XYZ-positioning system to permit fully automated measurements of angle-dependent characteristics or the homogeneity of displays.

The TOP 200 telescopic optical probe for launching light radiation and the flexible optical fiber with patented mode mixer offer the following advantages:

  • Modified Pritchard style optical design with simultaneous decoupling of the measurement aperture from the spectral resolution (band pass)
  • Different optical probes can be changed without loss of calibration (all accessories from Giant are plug-and-play)
  • All functions carried out by the TOP 200 can be controlled using software
  • Very low polarization sensitivity

A range of lenses is supplied for the TOP 200 and a bayonet connection allows them to be changed easily. This covers a wide range of different measuring spot sizes and distances to the display.

In addition to spectroradiometric measurement solutions, we also offers the LumiCam series of imaging photometers and colorimeters for two-dimensional display testing. An extensive software package is provided that features comprehensive functions for measuremnet analysis and reporting.
