Overview

The AvaSpec-ULS2048XL-EVO back illuminated fiber spectrometer is a successful combination of high quantum efficiency and high measurement speed. Unlike other back illuminated CCD detectors that use a planar array, the linear array large-sized pixel detector (14 500 μ m) has very high efficiency in both ultraviolet (200-400nm) and near-infrared (950-1160nm).

Product Details

AvaSpec-ULS2048XL-EVObackPhoto stylefiber optic spectrometerIt is a fiber optic spectrometer that successfully combines high quantum efficiency and high measurement speed. Unlike other back illuminated CCD detectors that use an array,Using a linear array large-sized pixel detector (14 × 500 μ m), it has very high efficiency in both ultraviolet (200-400nm) and near-infrared (950-1160nm).

AvaSpec-ULS2048XL-EVObackPhoto stylefiber optic spectrometerThere is also an electronic shutter, which allows for a short 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.

The AvaSpec-ULS2048XL-EVO spectrometer also comes with an optional anti second order diffraction filter, which can reduce the second order diffraction effect. There is also a purge gas connector used in deep ultraviolet measurements.Connected to the computer via a USB3 cable, it has a data transfer speed of 2ms. The AvaSpec-ULS2048XL-EVO spectrometer comes standard with AvaSoft Basic software, an operation manual (including a quick operation guide), and a USB cable.
