High-Resolution Spectrometer - AvaSpec-ULS3648

The AvaSpec-ULS3648 is a leading spectrometer within the field of high-resolution. It allows very short integration times (10 microseconds) due to an electronic shutter, which also means it is highly efficient for CW laser analysis.

Various customisable aspects are available, such as order-sorting filters which function to stop 2nd order effects and deep-UV detector layering which boosts detection within the deep-UV-range. Sensitivity can also be increased through the utilization of a detector collection lens. Slit sizes are available in a range of sizes, and gratings and fiber-optic entrance connectors are also available.

A range of configurations are available, including 2 to 10 channel spectrometers. Multiple channels enable the collection of several simultaneous results. It also allows increased optical resolution through the use of several spectrometers, each analysing a short range with high-resolution.

This equipment is linked to your computer via USB2 at 480 Mbps, resulting in 3.7 ms per scan data transfer speed. It comes with various components such as AvaSoft-Basic, USB cable and a highly informative manual, which has a fast start-up guide in four languages.
