Custom sapphire lenses that are impervious to blood, harsh chemicals, and chlorine and fluorine gas for use in a wide range of medical sensors and instruments are available from Meller Optics.

Meller Sapphire Medical Lenses feature Mohs 9 hardness which is second only to diamond for withstanding the rigors of frequent use and sterilisation procedures.

They are available round or square, concave or convex, flat or stepped, and can incorporate holes, edge treatments, metallisation, and coatings to enhance transmission to more than 99%, depending upon thickness.

Suitable for use in medical and laboratory instruments and sensors, Meller Sapphire Medical Lenses are precision manufactured to OEM specifications in 6.35-22.54mm dia. sizes and transmit from the UV to 4.7 microns.

 Flatness can be held to 1/10th wave, with parallelism to 2 arc-sec, and surface finishes to less than 0.5 mm. Other sapphire optics are offered.
