Materials laboratory needed for measurements on an anti-reflection coating on both external surfaces of a cemented doublet measured. The diameter of the doublet is 110mm, and the focal length 500m. The reflectance of the coatings is specified as < 0.2% at 632.8nm and normal incidence, whereas we measure > 0.4%. I am looking for measurements from an independent laboratory to convince the vendor to take the lens back.
