AvaSpec-ULS2048L
Enhanced Sensivity, General Purpose Fibre Optic Spectrometer
​
​
A close cousin to the AvaSpec-ULS2048 but with larger pixels is the AvaSpec-ULS2048L. It provides enhanced sensitivity at an affordable price due to the detector having pixels that are almost four times higher than those in the AvaSpec-ULS2048. It also has twice the signal to noise ratio and 40% less dark noise.
​
Options include deep UV detector coating for enhanced performance in the deep UV-range, a detector collection lens to enhance sensitivity in the 200-1100nm range, and order-sorting filters to reduce 2nd order effects. In addition, the AvaSpec-ULS2048 is available with a wide range of slit sizes, gratings and fiber-optic entrance connectors to perfectly tailor it to your aplication.
​
The AvaSpec-ULS2048 is also available in dual or multi-channel versions (up to 10 spectrometers in a 19” rack), where all spectra is captured simultaneously.
​
Connection with your PC is simple via USB2 interface, delivering a scan every 1.8 milliseconds. Integration time can be as short as 1.1 milliseconds up to a maximum of 10 minutes. It comes complete with AvaSoft-Basic software, USB cable and an extensive manual, including a quick start guide in four languages.
