Alpha300RA AFM & RAMAN
UHTS 300, Ultrahigh throughput lens based spectrograph with 300 mm focal length.
Andor Back illuminated CCD camera with >90% QE in the visible region. The CCD chip is a 1024 x 127 pixels with the pixel size of 24 microns
The instrument is a WITec alpha300RA (WITec GmbH, Ulm, Germany) AFM, SNOM &RAMANcombined system. The laser is coupled into the microscope using a single mode optical fiber coupling and the RAMAN signal is collected into a multimode optical fiber which is connected to the UHTS 300 spectrograph equipped with a back illuminated CCD with better than 90% QE in the visible region.
532 nm DPSS laser with a maximum power after single mode fiber of around 70 mW.633 nm with maximum output power after single mode fiber coupling of 35 mW
UHTS 300 is equipped with a motorized turret that can mount 3 gratings. The gratings available with the instrument are 600 g/mm BLZ 550 nm & 1800 g/mm BLZ 550 nm.
Modified Zeiss Axioscope.
