||| |||

The AvaSpec-ULS2048x16 is the best option when looking for a cost-effective, highly sensitive spectrometer. The back-thinned Hamamatsu detector features a signal-to-noise ratio of 500:1 and a quantum effeciency of up to 78%.

Options include an order-sorting filter to reduce second-order effects and purge ports for deep-UV measurements. The AvaSpec-ULS2048x16 comes with a wide range of slit sizes, gratings and may be configured with SMA or FC/PC fiber-optic entrance connectors.
The AvaSpec-ULS2048x16 is also available in dual or multi-channel versions (up to 10 spectrometers), where all spectra are acquired simultaneously.
Connection to your PC is handled via a USB2 connection, delivering a scan every 1.8 milliseconds. The instrument comes complete with AvaSoft-Basic software, USB cable and an extensive manual, including a quick start guide in four languages.
