LAB-LMS-100 and LAB-LMS-200 Light Measurement Spheres
Measure Total and Forward Flux of LEDs

The LAB-LMS-100 and LAB-LMS-200 Light Measurement Spheres are integrating spheres designed for the measurement of the total flux of lamps. The total flux of an unknown lamp is not measured directly; it is based on a comparison to a NIST-traceable standard lamp.

Innovative Design

The inside of the sphere is coated with Spectraflect^{?/sup>, a diffuse white reflectance coating specially formulated for light measurement spheres. An electrical feed-through to connect the lamp to a power supply terminates at the lamp socket mounting plate in the sphere. This design with accessible ports and framing accommodates light sources that are usually considered difficult to measure. The integrating sphere design conforms to recommendations of CIE Publication 84 and CIE 127, providing an easy-to-operate, highly accurate measurement component. The in-port Cosine receiver offers a wide field-of-view, necessary for accurate total flux measurements. The spheres provide measurement data that depends only on the light source's true power and not the shape size, spectral or spatial light distribution.}

Two Models = Two Sphere Sizes Available

Two sizes of LAB-LMS spheres are available:

• LAB-LMS-100 10-inch Light Measurement Sphere: Has a 10-inch diameter for the measurement of miniature and subminiature lamps with maximum lamp wattage up to 100 watts and high brightness LEDs. The sphere is designed for rail-mounted, heat-sinked LED measurements as well as other forward-flux measurements.
   
• LAB-LMS-200 20-inch Light Measurement Sphere: Has a 20-inch diameter for the measurement of miniature and small lamps with maximum lamp wattage up to 400 watts. The hinged design allows the sphere to be easily opened and closed to change lamps or perform a measurement and is perfect for bench-top use.
