> UV to SWIR sensor test bench INTEGRATING SPHERE SOURCE CLOSED LOOP CONTROL OF LUMINANCE FOR A RELIABLE OUTPUT Reference sources for the calibration of sensors on UV to SWIR wavelength range: The ISV Integrating Sphere Sources are compact, reliable and easy-to-operate reference sources providing an adjustable luminance output with unprecedent accuracy and stability, over the UV-Vis-NIR-SWIR spectral range. The ISV Integrating Sphere Sources have been specifically designed for the calibration and test of cameras and sensors such as night vision systems, image intensifier cameras, radiometers, UV-vision enhancement systems, focal plane arrays and optical detectors. Wide luminance range with superior accuracy, stability and uniformity: ISV Integrating Sphere Sources utilize closed loop control of the detector/attenuator system to precisely set and maintain the desired output level. A detector continuously monitors the output of the lamps and provides feedback to the attenuator, leading to very stable and repeatable performance. Integrating Sphere UNIQUE 5000K COLOR TEMPERATURE ON UV ENHANCED MODELS High radiance level from 200nm to 2500nm wavelength range: the ISV210 and ISV410 standard models combine up to four tungsten halogen lamps, calibrated to the National Institute of Standards and Technology (NIST) traceable color temperature of 2950 ± 25 K. They provide a stable and uniform stimuli for the characterization of sensor systems over visible to SWIR spectrum, with an adjustable luminance from 1 to 85,000 cd/m2. The ISV410-UV model utilizes four Xenon arc lamps, with a color temperature of 5000K, providing a calibrated high level output over a spectral range from 200nm to 2500nm - ideal for the test and calibration of radiometers and UV enhanced cameras. > ISV410-UV model with 5000K color temperature lamp ISV410-LL: LOW LIGHT VIS AND NIR SOURCE WITH RADIANCE DOWN TO 10-11 W/cm2.sr The ISV410-LL is specifically designed for the test and calibration of low light level sensor systems which respond in the Visible and NIR light spectrum such as Night Vision Systems, image intensifier cameras, radiometers, remote sensing systems and UV-Vision enhancement systems. Illumination is provided by a tungsten halogen lamp, calibrated to a NIST traceable color temperature of 2856 ± 25 K. True color temperature is achieved at low levels without the use of neutral density filters. A silicon detector continuously monitors the output of the lamp and provides feedback to the attenuator, providing very stable and repeatable performance. When ISV illuminators are used with a Target Wheel and Collimator, the system includes Minimum Resolvable Contrast, Uniformity and MTF utilizing variable contrast USAF1951, open area and knife-edge target tests. HGH offers a complete line of testing software to automate these and other test procedures. > ISV410-LL Low Light Integrating Sphere
