Rapid-Scan VIS Spectrophotometric Color Analyzer

The LMS-5000 Rapid-Scan Mechanical Spectrophotometric Color Analyzer is a widely deployed single-monochromator spectrophotometer delivering laboratory-grade measurement accuracy. Typical spectral acquisition across the 380-800nm wavelength range requires less than 10 seconds. When integrated with appropriately sized integrating spheres and calibrated reference light sources, the LMS-5000 system enables comprehensive spectral characterization of LED devices, LED modules, compact fluorescent lamps (CFL), fluorescent tubes, cold cathode fluorescent lamps (CCFL), high-intensity discharge (HID) lamps, and various luminaire assemblies.
