GS-1150 Handheld Spectrophotometer for Light Measurement

Gamma Scientific’s new GS-1150 handheld spectrophotometer is a stand-alone instrument designed for lighting installers, designers and engineers who require accurate, low cost spectral measurements.

The GS-1150 is ideal for the spectral evaluation of LEDs, OLEDs, CFLS, displays and traditional lamps.

Based on a compact Czerny-Turner design spectrophotometer with a 2048 element linear CCD array, the GS-1150 measures light intensity and color with 0.2nm resolution.

The GS-1150 spectrophotometer features a full-color, LCD touch-screen display and Android based software for intuitive operation.


The battery powered instrument is ideal for both laboratory and field use. Up to 500,000 files can be stored in the GS-1150 and quickly exported to Excel.
