AvaSpec-ULS2048XL-EVO High UV Near Infrared Sensitivity Back Illumination CCD Spectrometer
AvaSpec-ULS2048XL-EVO is a fiber optic spectrometer that successfully combines high quantum efficiency and high measurement speed. Unlike other back illuminated CCD detectors that use a planar array, the AvaSpec-ULS2048XL-EVO spectrometer uses a linear array large-sized pixel detector (14 × 500 μ m), which has very high efficiency in both ultraviolet (200-400nm) and near-infrared (950-1160nm). The AvaSpec-ULS2048XL-EVO spectrometer is also equipped with an electronic shutter, allowing for an integration time of up to 2 microseconds. To further increase sensitivity, there is also a sensitivity enhancement lens option that can increase sensitivity by 60% when used with large core diameter fibers.
