Fourier spectral viewing angle measurement instruments with high performance ELDIM Company manufactures viewing angle analyzers According to fourier spectral principles for more than 10 years.

The systems developed by us become better and better In terms of ability in full viewing angle and big light spot year by year.

Multi-spectral series products adopt most advanced optical Design principles with viewing angle range up to 88° .

High efficiency

One of key characteristics of this system is that it adopts a kind Of patent technology; It can control system's aperture angle and Size of light spot independently. High collection efficiency, Viewing angle up to 88° with extremely high precision are key Advantages and development of this patent compared with Traditional fourier optical analysis.

High speed analysis

This full viewing cone graph is measured with extremely High azimuth angle resolution. It only takes several minutes to Measure luminance as well as radiation. Holographic graphs of Films and components can be formed in seconds. Goniometer is Used to measure them by the traditional way and it usually takes Several days.

High precision

All ELDIM's systems follow strict processing procedures, Quality control and correction procedure. Every CCD camera Is with higher spectral sensitivity and every filter's design and Spectral sensitivity are controlled through the method of Spectrophotometry. We develop special tools and procedures to Make systems achieve high viewing angle.

High reliability

ELDIM independently processes systems' every key component. Its performance is very high due to adoption of advanced Technology: Magnetic fluid polishing technology, stitching intervening Method, etc.

In order to reduce polarization of low direct light and derivative Light, we paint non-reflective light coating on the surface and make Optical calibration within system. Optical calibration and coating Painting are made in dust-free rooms. All systems will be tested to Make sure quality several days before they will be transported.

Radiation luminance color and polarization EZContrastMS can not only measure wave Length of spectrum but also finish light's Polarization state. Polarization state is very useful In comparison of LCDs, characterization of films And components, stereoscopic display-based 3D performance, etc.
