PLMS PHOTOPIC LAMP MEASUREMENT SYSTEMS
Accurate, easy-to-use systems for measuring total luminous flux
FEATURES:
- NIST Traceable Calibrated Spectral Flux Lamp Standard
- Spectraflect® Interior
- External Forward Flux Port
- Latch-free Clamshell Design
- CIE Recommended Geometry for Total and Partial Flux
Labsphere's PLMS Photopic Lamp Measurement Systems are integrating sphere photometers designed to measure the total luminous flux of lamps.
The systems are capable of measuring all lamp types including arc, fluorescent, incandescent and HID. Available in 10, 20, 40, 65 and 76 inch diameter integrating sphere sizes, each diameter accommodates a particular class of lamp defined by its physical size and output flux rating. The interior of the spheres are coating with Spectraflect® Diffuse Reflectance Coating which combines 98% reflectance with nearly perfect Lambertian properties.
PLMS Systems conform to the recommendations of CIE Publication 84, providing easy-to-operate highly accurate measurement systems.

The PLMS integrating sphere includes a 3 inch satellite sphere with an integral baffle cosine collector and photopic response detector. This assembly offers a wide field of view, necessary for accurate total flux measurement. A precision-regulated DC power supply provides highly accurate currents for lamp standard measurements. The SC 6000 radiometer/photometer operates out-of-the-box, with a 64 digit back lit display that allows users to view measurement results, select calibration factors and set display features and remote communication parameters.
The cosine receiver with an integrated photometer collects the average sphere wall radiance. The sphere design enables testing within CIE recommended geometries, reducing errors associated with directional lamps. The lamp standards of total luminous flux provide NIST traceable results with every measurement. An optional auxiliary lamp corrects for device under test (DUT) absorption differentials for added precision.
A Calibrated Luminous Flux Standard is supplied with each PLMS traceable to National Institute of Standards and Technology (NIST).
