The Model 207A is a 670 mm focal length, optically fast f/4.7 monochromator that is now available with off-axis parabolic optics. The off-axis parabolic (OAP) mirrors provide both low f-number and stigmatic monochromator performance. Highly polished OAP mirrors with smooth surfaces are suited for work in the deep-UV and vacuum region.
