Accordingly, they have zero chromatic aberration, and negligible coma, spherical, and astigmatic aberrations. We offer 15X and 36X objectives, broadband coated with aluminum and over coated with magnesium fluoride (MgF2). They are usable from 200nm to 20ìm. Special coatings are available upon request including MgF2 optimized for the 157 to 195nm region, and gold for the visible to IR region.
