Need 5029.jpg!Lamp Measurement Spheres are integrating spheres designed for the measurement of the total luminous flux of lamps. The total luminous flux of an unknown lamp is not measured directly; instead this measurement is based on the known lumens of a standard lamp. Lamp Measurement Spheres range in size from 10 to 105 inches in diameter. Five different sphere diameters accommodate lamp sizes from miniature incandescent to 60 inch fluorescent lamps. The sphere interior is coated with Spectraflect, a diffuse white reflectance coating specifically formulated for lamp measurement spheres. An 80% reflectance coating is available for spheres used in photopically filtered applications. The integrating sphere design conforms to recommendations of CIE Publication 84, providing an easy-to-operate, highly accurate measurement system. An electrical feed-through to connect the lamp to a power supply terminates at the lamp socket mounting plate in the sphere. The LMS sphere is equipped with a cosine collector sphere assembly that consists of a three inch diameter sphere with an internal 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 measurements.

LMS-100

The LMS-100 is a 10 inch diameter integrating sphere which accommodates measurements of miniature and subminiature lamps with a maximum lamp wattage up to 100 watts.

LMS-200

The LMS-200 is a 20 inch diameter integrating sphere mounted on a hinged frame designed for bench-top use. The hinged configuration allows the sphere to be easily opened and closed to change lamps or perform a measurement. The sphere is designed for measurement of miniature and small lamps with a maximum lamp wattage up to 400 watts.

LMS-400

The LMS-400, a 40 inch diameter integrating sphere, is mounted on a hinged frame equipped with rugged locking casters to allow the sphere to be rolled and locked into position. The hinged configuration allows the sphere to be easily opened and closed to change lamps or perform a measurement. The sphere contains a lamp mounting bracket designed to accept a variety of sockets for single contact and double contact lamps. The integrating sphere accommodates measurement of small and medium lamps with a maximum length of 24 inches and a maximum lamp wattage up to 1500 watts.

LMS-650

The LMS-650 is a 65 inch diameter integrating sphere mounted on a hinged frame equipped with rugged locking casters to allow the sphere to be rolled and locked into position. The hinged configuration allows the sphere to be easily opened and closed to change lamps or perform a measurement. The lamp mounting bracket for this sphere is a similar design to that in the LMS-400. The sphere is designed for measurement of medium to large lamps with a maximum length of 48 inches, and a maximum lamp wattage up to 4000 watts.

LMS-760

The LMS-760 is a 76 inch diameter integrating sphere mounted on a hinged frame equipped with rugged locking casters to allow the sphere to be rolled and locked into position. Each hemisphere is mounted to a separate carriage, allowing the sphere to be easily opened and closed to change lamps or perform a measurement. The lamp mounting bracket for this sphere is a similar design to that of the LMS-400. The sphere is designed for the measurement of medium to large lamps with a maximum length of 52 inches and a maximum lamp wattage up to 5000 watts.

OPTIONAL ACCESSORIES

Optional accessories are available for the LMS lamp measurement spheres. They include calibrated luminous and spectral flux lamp standards and auxiliary lamps.
