Product details
AvaSpec-ULS2048CL-EVO high-speed CMOS spectrometer

AvaSpec-ULS2048CL-EVO uses CMOS technology instead of traditional CCD technology. AvaSpec-ULS2048CL-EVO, combined with the newly launched AS-7010 circuit board, presents you with multiple functions, including USB 3.0 communication (ten times faster than USB 2.0 communication speed) and Gigabit Ethernet communication. Gigabit Ethernet communication enables the spectrometer to be integrated into your company network, saving you the cost of long-distance communication. In addition to high-speed communication, EVO also provides a fast microprocessor and more than 50 times the storage space of the spectrometer, which can help you store more spectra and achieve more functions.

Additional options include a sensitivity enhancement lens that increases sensitivity in the 200-1100nm wavelength range, as well as an anti second order diffraction filter. In addition, AvaSpec-2048CL-EVO also offers different specifications of slit, grating, and fiber optic connectors to choose from. Standard accessories include AvaSoft Basic software, USB cable, and user manual. AvaSpec-ULS2048CL-EVO is also available in OEM, standalone optical platform, or Rackmount versions.
