AvaSpec-2048FT-4-RM Fiber Optic Spectrometer 
The AvaSpec-2048 Fiber Optic Spectrometer is based on the AvaBench-75 symmetrical Czerny-Turner design with 2048 pixel CCD Detector Array.
The spectrometer has a fiber optic entrance connector, optical slit, cylindrical collimating lens, for higher sensityviti colli-mating and focusing mirror and diffractional grating.
The spectrometer has a fiber optic entrance connector, optical slit, cylindrical collimating lens, for high sensitivity, focusing mirror, diffraction grating, coating detector.
The AvaSpec-2048 is also available as dual channel or multiple channel instrument (up to 8 channels), where all spectra are taken simultaneously. The AvaSpec-2048 comes with AvaSoft-basic, a complete manual, USB interface cable and a PS-12V/1.0A power supply. AvaSoft-full and application software can be ordered separately. Alternatively the AvaSpec-2048-SPU is available as an option to run on USB power and does not need an additional power supply.
