PLMS Photopic Lamp Measurement Systems are integrating sphere photometers designed to measure total luminous flux of lamps. The systems accommodate all lamp types including arc, fluorescent, incandescent and HID.

Five integrating sphere sizes are offered, each designed to accommodate a particular class of lamp defined by their physical size and flux. Each system includes a lamp measurement integrating sphere, a calibrated luminous flux standard, lamp power supply, a photopic sphere detector assembly and an SC-5500 Integrating Sphere System Control.

Lamp measurement integrating spheres range in size from 10 to 76 inches in diameter. The sphere design conforms to the recommendations of CIE Publication 84, providing easy-to-operate highly accurate measurement system. The sphere interior is coated with Spectraflect, a diffuse white reflectance coating specifically formulated for lamp measurement.

The Lamp measurement integrating sphere is equipped with a cosine collector sphere assembly that consists of a three inch diameter integrating sphere with an integral baffle and photopic response detector. The assembly adapts to the measurement port of the sphere and offers a wide field of view, necessary for accurate total flux measurement.

Each PLMS Photopic Lamp Measurement System includes a precision-regulated DC power supply to provide highly accurate currents for lamp standard measurements. An SC-5500 Integrating Sphere System Control operates the lamp measurement system from either a 7-key front panel control or via a computer. The SC-5500 contains both IEEE-488 and RS-232C ports for maximum flexibility in computer connection. The lamp power supply and SC-5500 Integrating Sphere System Control are packaged in a rack-mount console.

Standards and Calibration

A Calibrated Luminous Flux Standard is supplied with each lamp measurement system. Lamp standards are calibrated in our Optical Calibration Laboratory with standards traceable to national laboratories.

Custom Software Development

Windows-based software programs are available for enhanced operation of lamp measurement systems. Please contact the Labsphere Technical Sales Department to discuss available software options for specific applications.

OPTIONAL ACCESSORIES

AUX-30 Auxiliary Lamp

Auxiliary lamps are available for use in more demanding measurements when the absorption of the test lamp must be considered. Labsphere recommends the use of an auxiliary lamp for situations where the physical configuration and characteristics of the test lamps differ from those of the calibrated lamp. The throughput of the sphere varies given such differences in lamps, and an auxiliary lamp corrects for these differences by providing a means of correcting for lamp absorption.

Calibrated Spectral Flux Standards Sets

Calibrated Spectral Flux Standard are sold in sets of three lamps. The lamps are calibrated for total luminous flux (lumens). The use of three lamps prolongs the useful life of each lamp since they may be used interchangeably. The multiple lamp sets allow the user to check lamps against each other to verify calibration data over time. A calibration certificate verifying traceability to national laboratorie standards is provided for each lamp in the set.

Spectral Lamp Measurement System Upgrade Packages

The SLP-100 and SLP-200 Spectral Lamp Measurement System Upgrade packages are available for customers who wish to upgrade their existing PLMS Photopic Lamp Measurement Systems. The SLP Upgrade Package consists of a calibrated lamp standard, lamp power supply, DAS Diode Array Spectrometer (TE-Cooled) and application software. Please note: Each SLP Upgrade Package accommodates a specific sphere size.
