Avantes StarLine : AvaSpec-ULS2048L Versatile Fiber-optic Spectrometer

A close cousin to the AvaSpec-ULS2048 but with larger pixels is the AvaSpec-ULS2048L.

AvaSpec-ULS2048L StarLine Versatile Fiber-optic Spectrometer

It provides enhanced sensitivity at an affordable price. The AvaSpec-ULS2048L has pixels that are almost four times higher than those in the AvaSpec-ULS2048. It gives you twice the signal to noise ratio and 40% less dark noise.

Options include a deep-UV detector coating, for better performance in the deep-UV-range, a detector collection lens to enhance sensitivity in the 200-1100 nm range and order-sorting filter to reduce 2nd order effects. Furthermore, the AvaSpec-ULS2048L is available with a wide range of slit sizes, gratings and fiber-optic entrance connectors.

The AvaSpec-ULS2048L is also available in dual or multi-channel versions (up to 10 spectrometers), where all spectra are taken simultaneously.

Connection to your PC is handled via USB2-connection, delivering a scan every 1.8 millisecond. Integration time can be as short as 1.11 millisecond 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.
