This compact, lightweight instrument features a 2-inch diameter integrating sphere that collects the total light entering the sphere measurement port. The sphere interior is fabricated from a nearly-Lambertian (perfectly diffuse) reflectance material.
Portable and easy to operate, this compact system is designed for use in the field, laboratory, or production floor, the instrument measures luminous flux from sources such as LEDs, small lamps, and fiber illuminators. The instrument’s photopic filtered silicon detector provides maximum sensitivity at low light levels. A calibration certificate traceable to NIST is included. Housing has an M6 tapped hole for post mounting. The LED adapter kit, sold separately, includes entrance port adapters for standard LED package sizes including 2mm, 3 mm (T1), 4 mm, 5 mm (T1-3/4), 8 mm and 10 mm.
