The **AvaSpec-ULS2048XL-EVO** is a high-performance spectrometer designed for those who demand superior sensitivity and speed in their spectroscopic measurements. This state-of-the-art instrument is part of the SensLine series, known for its enhanced UV and NIR sensitivity. At its core, the AvaSpec-ULS2048XL-EVO features a back-thinned CCD detector with large monolithic pixels measuring 14x500 microns. These large pixels contribute to its exceptional quantum efficiency, particularly in the UV range from 200-400 nm and the NIR range from 950-1160 nm. This makes it an ideal choice for applications requiring precise UV and NIR detection.

A key advantage of the AvaSpec-ULS2048XL-EVO is its high-speed capabilities, courtesy of its advanced AS7010 electronics board. This board supports USB3 and Gigabit Ethernet connections, allowing for rapid data transfer and enhanced signal processing. Users can achieve scan speeds as fast as every 2 milliseconds, ensuring that no detail is missed in dynamic measurements. Additionally, the spectrometer's electronic shutter allows for integration times as short as 2 microseconds, providing flexibility for a wide range of experimental setups.

The design of the AvaSpec-ULS2048XL-EVO is both versatile and user-friendly. It offers a variety of configuration options, including different slit sizes, gratings, and fiber-optic entrance connectors (SMA or FC/PC). To further boost its sensitivity, an optional detector collection lens is available, enhancing sensitivity by up to 60% when used with larger core fibers. For those concerned with second-order effects and deep-UV measurements, the spectrometer can be equipped with an order-sorting filter and purge ports. The comprehensive package includes AvaSoft-basic software, a USB cable, and a detailed manual, ensuring that users have all the tools they need to get started quickly and effectively.
