Spectroradiometers

High-Speed Spectroradiometer Systems for Precision Testing of LEDs, Flat Panel Displays & Night Vision Equipment

The RadOMA Series Platform is a durable opto-electrical design proven in hundreds of facilities worldwide. Experience the RadOMA advantage offering advanced, high-speed spectroradiometers that combine the leading-edge sensitivity of a backside-thinned CCD detector with Gamma Scientific’s industry-renowned OMA optical multi-channel analyzer opto-electrical platform.

The RadOMA Series features millisecond measurement speed, exceptional low-light measurement capability and superior blue-light region sensitivity at least two times greater than conventional front-illuminated CCD-based systems. RadOMA spectroradiometers are ideally suited for testing LED color and luminance, flat panel displays, retroreflected color, reflectance, transmittance and light sources.

Multiple configurations cover a wide spectral range from ultraviolet to the near infrared: 200 to 780 nm (model GS-1290-0); 260 to 890 nm (GS-1290-1); 300 to 1100 nm (GS-1290-2); or 380 to 800 nm (GS-1290-3).

As with all Gamma Scientific’s products, each system is completely modular and interchangeable, so it can be easily upgraded or customized to fit your needs. Automatic Dynamic Range Optimization ensures system electrical gains are always set for the best results. Interfacing the RadOMA via USB 2.0 to Gamma Scientific’s powerful Windows-based Light Touch spectral data acquisition and analysis software package rounds out a comprehensive solution.

RadOMA spectroradiometer systems come with factory NIST-traceable calibration and can be self-calibrated by the user, so they never have to be returned to the factory for calibration. Calibrations take just seconds using a calibrated standard source.

LED Spectroradiometer

The RadOMA-LED spectroradiometer provides high accuracy and near-perfect repeatability. The results are precise, millisecond measurements for LED spectra of all colors.

The system is easily configurable to measure different aspects of LED output, including spectral radiant intensity, luminous intensity, total flux measurements and spatial intensity.

 
 
 
 
 
 
 
 
 
 

RadOMA Spectroradiometer for Flat Panel Display Testing

Spectral measurements of displays can be repeatedly taken in milliseconds with ultra-low uncertainty.

Any application that demands high sensitivity in the blue-light region, for example LED backlit displays, will benefit from this system’s back-thinned CCD technology – its sensitivity is at least two times greater than front-illuminated CCD-based systems.

 
 
 
 
 
 
 
 
 
 
 
 

NVIS Spectroradiometer

The GS-1290-NVIS is specifically configured for ANVIS testing of cockpit displays and lighting. It exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009.

Measurements that required a few minutes in the past with scanning grating spectroradiometer systems can now be performed in a matter of seconds.
