The Model 225 one-meter normal incidence (NIM) vacuum ultraviolet monochromator is sometimes referred to as the “McPherson 15°." The tight angle between entrance and exit slits results in an optical design with reasonable imaging and low polarization. Its unique wavelength drive translates the grating during rotation to maintain best focus at wavelength. This is an ideal high-resolution instrument for use with microchannel plate intensifiers or CCD detectors. It is a very clean design; the wavelength drive is outside the stainless steel vacuum vessel. We deliver it with single gratings, or double- or triple-grating turrets. It can be mounted horizontally or on its side, to save space.

The Model 225 is a high-vacuum instrument (10E-6 torr) and ultra-high vacuum (10E-10 torr) versions are available. We also make it with two, three and even 6-meter focal lengths that achieve resolving power 78,000 at 46.4nm.
