The Gamma Scientific GS-1190 is a high performance, linear CCD array spectrometer, with an 800 kHz readout speed. The spectrometer utilizes a 2048 element detector with 16-bit resolution. Computer interface is USB 2.0. The GS-1190 is ideal for quick and easy LED measurements for users on a budget. Flexible custom configurations and application support are available for OEM applications. The spectrometer accepts an SMA905 fiber-optic input that can be connected to a wide variety of optics including integrating spheres for total flux measurements or CIE127 Conditions A and B for intensity measurements. The system comes with the GS-1190 Windows software package for LEDs with automated report generation.
