Sapphire lenses and windows for Holmium and ER: Yag lasers, blood gas analyzers, centrifuges, ventilation and oximeter systems, and related instruments are available from Meller Optics, Inc. of Providence, RI.

Meller Medical Sapphire Optics are impervious to virtually all corrosive fluids and can be fabricated thinner than other materials because of the inherent high strength-to-thickness ratio of Sapphire.

Featuring surface finishes to 5 angstroms RMS and Moh 9 hardness; Meller Medical Sapphire Optics exhibits 1/10th wave or better surface accuracies at HeNe and can be supplied with various high power coatings including A/R coatings exhibiting <0.25% per surface @2.94um. They are available as plano-convex and plano-concave lenses and as windows to fit into packages or viewports.
