Request InfoColor and Light MeterGigahertz-Optik GmbHPUCHHEIM, Germany, Oct. 19, 2009 – Gigahertz-Optik GmbH’s handheld BTS256-LED is designed to measure luminous flux or illuminance, color data and spectral distribution of printed circuit board-mounted LEDs, discrete LEDs within a module, miniature lamps, endoscopes and any narrow beam-emitting light source. Larger size light sources can be measured by either attaching the LED tester to the company’s integrating sphere or by measuring illuminance using a screw-on diffuser window. Key components of the device include a built-in 50-mm-diameter integrating sphere with an interchangeable input optic nozzle designed to minimize...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueBandpass FiltersThe ADVANTECH™ hard coat bandpass filters from Andover Corp. offer steep slopes, high light transmission, durability, and long life for demanding applications.
