Uniform Source Spheres

Applications:

• Calibration and testing of Detectors, Electronic Imaging Devices, and CCD Cameras
• Calibration of Photometers and Radiometers
• Illumination of Densitometry and Resolution Targets
• MTF Testing of Optical Systems
• Transmittance Measurements of Fiber Optics

Labsphere Uniform Source Integrating Spheres and Systems are the industry choice for the calibration and test of cameras and sensors ranging from optical detectors, and focal plane arrays to multi-spectral remote sensing systems.

The integrating sphere interiors are coated with Labsphere's highly reflective and durable Spectraflect® coating and the mounting frame enables sphere height adjustment and rotation for the US-120 and the US-200 to position the exit port aperture in a vertical or horizontal plane.

US-060 6 Inch Uniform Source Integrating Sphere
The US-060 is a 6 inch diameter integrating sphere that provides exceptional uniform luminance over the full
2 inch diameter of the sphere exit port. A smaller, 3 inch diameter satellite sphere is fixed to the sphere, providing a source of light into the larger, 6 inch sphere. An iris diaphragm between the two spheres controls the size of the aperture and the amount of light entering the larger sphere. The satellite sphere has a 1 inch diameter lamp port that accepts the standard halogen light sources. To prevent direct illumination from the lamp into the wall of the larger sphere, a diffuser has been placed between the two spheres.

US-080 8 Inch Uniform Source Integrating Sphere
The US-080-SF is an 8 inch diameter integrating sphere the with an inline baffle to provide uniform luminance through the 2 inch port framed exit port. The sphere is coated with Spectraflect coating. A 1-inch port framed entrance provides a mounting for Labsphere internal and external light source assemblies. For variable the radiant flux entering sphere simple add one of Labsphere’s variable light attenuator between the light source and the sphere. Need a specific uniform spectrum? Simply add one of Labsphere filter holders between the sphere and external light source and filter the light entering the sphere to address your application. The 0.5–inch port framed detector port is designed to receive Labsphere photopic and unfiltered UV-VIS-NIR detectors.

US-120 12 Inch Uniform Source Integrating Sphere
The US-120-SF is a 12 inch diameter integrating sphere that provides exceptional uniform luminance over the full 4 inch diameter of the sphere exit port frame. Four 1 inch diameter lamp ports are equally spaced around the exit port; the lamp ports are baffled to prevent direct radiation from reaching the exit port from each individual lamp. Two additional 0.50 inch port frames are provided adjacent to the exit port to accommodate output monitors.

US-200 20 Inch Uniform Source Integrating Sphere
The US-200-SF is a 20 inch diameter integrating sphere that provides exceptional uniform luminance over the full 8 inch diameter of the sphere exit port frame. Four internal lamp mounts are equally spaced around the exit port aperture; the lamp ports are baffled to prevent direct radiation from reaching the exit port from each individual lamp. Two additional 0.50 port frames are provided adjacent to the exit port to accommodate output monitors. Light source systems are designed to minimize color shifts with radiance level changes and provide the highest level of uniformity.
