Compact BiTec Spectroradiometer LED Tester for the Measurement of Total Luminous Flux of Single VIS and NIR LEDs

ISS-8P-VA

Integrating Sphere Source with Variable Intensity Control

80 mm sphere diameter, 19 mm luminous port diameter, ODM98 coating, halogen lamp
Intensity control with manual (VA) or automatic (VAM) variable attenuator
Options: VA, VAM, different halogen lamps (10W or 100W), calibrations of luminance, spectral radiance, lamp power supply

The uniform light source ISS-8P-VA is based on a ODM98 coating and offers an 19 mm light entrance port. Furthermore the system is equipped with a LS-OK30 light source and a manual aperture (LS-OK30-VA) for continuous intensity adjustment (luminance/radiance).

Intensity adjustment

With the help of the manual aperture the radiance/luminance of the sphere can be continuously adjusted to the desired level. A quality measure for the intensity adjustment is a constant color temperature and no change in the homogeneity of the light entrance port. Both are achieved by the ISS-8P-VA.

The light source can be equipped with LF-F or LH-F-UV quartz halogen lamps in the range of 5 W to 100 W. The power will be selected according to the needed radiance/luminance.

Calibration

A calibration with included calibration certificate (cd/m²) and/or spectral radiance (W/(m²sr)) which is traceable to a national standard can be optionally purchased. The calibration is done by our internal calibration laboratory.
