What is New

 VCMaster3D

ELDIM's VCMaster 3D device feature an ultra high angular resolution for precise characterization of the 3D contents whatever the technology. ELDIM's VCMaster 3D also includes brand new software tools specific to this technology with most of major parameters...

Autostereoscopic 3D display characterization is essentially a problem of angular emission. Each point of the surface of the display must emit two or more images that must arrive in the left and right eyes of the observer.

ELDIM manufacture viewing angle instruments based on Fourier optics for more than 10 years. One of their key features is the patented optical configuration which allows controlling the angular aperture of the system independently of the measurement spot size. The very high light collection efficient allows measurement up to very extreme grazing angles (88°) with an excellent accuracy. ....

Conometer80

Easy to use and far more cost effective than traditional conoscopic systems, the CONOMETER 80 is ideal for measuring the viewing angle luminance, contrast and gamma (new!) of emissive displays such as LCD, plasma, OLED, FED and rear-projection displays. The system is well suited for use in QC, production process control and R&D.

By using Lumetrix's Electronic Bracketing, the system can measure from 0.0005 to 4,500 cd/m2 without the use of neutral density filters. Very high contrast ratios are measurable.

The simple optical design has fewer optical elements than competitive conoscopic (Fourier) lens configurations. The system is able to measure displays as small as 6mm wide. The simpler optical design also results in lower optical scattering (low stray light).

XR-Series Miniature Fiber Optics Spectrometers

 


The XR-Series of Extended Range Spectrometers from Ocean Optics are responsive across a wide spectral range, providing you an optical resolution of ~2.0 nm (FWHM) and the convenience of a single, monolithic spectrometer to cover all wavelengths from ~200-1050 nm.

 

The XR Option is now available for our USB2000+, Jaz-EL200 and USB4000 Spectrometers and in custom systems.

Specbos 1201 / 1201M in their basic configuration can measure Luminance only with diameters of 4 mm and

more. Therefore four focusing optics were developed to allow the measurement of spots with 3 mm, 1 mm, 0.5 mm and 0.25 mm diameter. These spots are marked by a laser circle. The 0.5 mm and the 0.25 mm add ons are fitted out with a magnifying glass to simplify the precise adjustment.

Measuring objects:

  • Alphanumerical and numerical displays
  • Fluorescent tubes with small diameter
  • Backilluminated signs
  • Other small light sources

    The Lumetrix STiR 1.4 Spectrally Tunable Imaging Radiometer is a unique instrument: it delivers high performance spectroradiometric measurements from 400 nm to 720 nm in a 1400 x 1040 image. Radiance images at each wavelength are compiled and computed to report values at each pixel in the image such as CIE chromaticity, luminance, and radiance. The system's exceptional performance specifications include: low stray light, 1nm accuracy, a nominal bandpass resolution of 7nm, and more than six decades of dynamic range.

    Measurement applications include the characterization of displays, LEDs and lamps. Users of spot spectroradiometers will appreciate the STiR for its speed and comprehensive measurement detail. The STiR offers the intuitive ability to superimpose measurement data on an image. Spectral data at every point in the image provides engineers with enhanced analysis not previously possible.
