SR65 Scientific-Grade Spectrometer vs QE65
SR65: Precision Spectroscopy for Demanding Applications
New standard in miniature fiber-optic spectrometers. The SR65 combines exceptional sensitivity and stability for a wide range of demanding analytical and research applications. Featuring a low stray light optical bench, low-noise electronics, and a high quantum efficiency back-illuminated CCD detector.
Its deep-cooled CCD, capable of thermoelectric cooling up to 40°C below ambient, significantly reduces dark current and thermal noise, enabling extended integration times and improved detection limits. Ideal for low-light level applications and environments with fluctuating temperatures.
