The Model 248/310 from McPherson is a Grazing Incidence UV Monochromator that operates from 1 to 310 nm. It has a focal length of 1000 mm and a spectral resolution of up to 0.16 nm. The monochromator operates using interchangeable diffraction gratings. It has a Rowland circle configuration that ensures a good focus and spectral resolution are possible at the wavelength of interest.
This monochromator consists of a chord-length meter and has a manually operable wavelength drive for accurate and reproducible wavelength positioning. It is available in a compact housing and is ideal for XUV, soft X-ray (SXR), and extreme UV applications.
