Spectroradiometers

  • Product No:GS 1290
  • Manufacturer:Gamma Scientific

GS-1290 Spectroradiometers provide high accuracy and near perfect repeatability. Multiple models cover UV, Visible and near-IR wavelengths for use in a wide range of testing applications. GS-1290 spectroradiometers are designed for laboratory use and quality control applications.

GS-1290 Spectroradiometers feature 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. GS-1290 Spectroradiometers are ideally suited for testing LED color and luminance, flat panel displays, retroreflected color, reflectance, transmittance

Accessories

Integrating Spheres

2M-Integrating-Sphere

 

Available in a wide range of sizes from 25mm to 3m in diameter. Multi-purpose integrating spheres provide maximum flexibility and are custom built to meet your exact testing requirements. Light measurement spheres for LED testing are optimized for capturing total flux measurements of LEDs.


Goniometers

940 LED 1200 Goniometer

 

Gamma Scientific’s 940 LED-1200 and 940 LED-1850 Goniometers are designed to analyze angle dependent spatial radiation properties of LED luminaires, lamps and modules.


Calibration Light Sources

RS-14 Uniform Light Source

 

Gamma Scientific manufactures a wide range of calibration light sources. The RS-10D is a precision source of radiant flux used to calibrate spectroradiometers and other light measurement instrumentation. The RS-12 is a versatile light source that can be used as a white light standard of spectral radiance or luminance, with optimal near-infrared output for spectroradiometer calibration.
