Different from other back-illuminated CCD detectors using area array, the spectrometer uses linear array large-size pixel detectors (14 × 500 μ m), which have very high efficiency in ultraviolet (200-400nm) and near infrared (950-1160nm). The spectrometer is also equipped with an electronic shutter, so that the integration time can reach 2 microseconds. To further increase sensitivity, there is also a sensitivity enhancement lens option, which can increase sensitivity by 60% when used with large core fiber.
