YC150 Standard Interferometer Lens (6-Inch) YC150-F3.5
YC150 series reference lenses provide accuracy better than λ/15 (@632.8nm). Their interfaces fit domestic and international interferometers of the same aperture; some differing interfaces require adapter rings. Specifications: F0.8/F1.1/F1.5/F2.2/F3.5/F5.4/F7.2/F15/plane TF&RF. Other F-number lenses can be customized.
