Monochromator by McPherson

Note: Your Quotation Request will be directed to McPherson.

The 234/302 from McPherson is an Aberration Corrected Vaccum Monochromator which has a focal length of 200 nm. It delivers a spectral resolution (FWHM) of 1200 g/mm grating with an angle of incidence at 32 degrees and has precision slits that are micrometer adjustable from 0.01 to 3 mm. The monochromator consists of a wavelength counter and a manually operable sine drive that provides accurate and reproducible wavelength positioning. It has a microchannel plate and CCD adapter and can be scanned using computer software. The monochromator has a grating size of 40 x 45 mm and is ideal for deep UV and vacuum ultraviolet applications.
