AvaSpec-ULS2048x16 Fiber Optic Spectrometers
The AvaSpec-ULS2048x64 features some of the highest pixels in the market today, perfect for situations where little light is available: large diameter fibers work perfectly with this small-sized spectrometer. Combine this with the great stability and you know why the x64 is the best option for these situations.
Options include order-sorting filter to reduce 2nd order effects, purge ports for deep-UV measurements. The AvaSpec-ULS2048x64 comes with a wide range of slit sizes, gratings and may be configured with SMA or FC/PC fiber-optic entrance connectors.
The AvaSpec-ULS2048x64 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 2.4 milliseconds. The instrument comes complete with AvaSoft-basic software, USB cable and an extensive manual, including a quick start guide in four languages.
