Meller Sapphire Lenses are manufactured to specification in plano-convex, plano-concave, meniscus, and dome configurations for extreme environmental applications requiring durability and critical focusing specifications. Featuring focal lengths from 3/4" to 1000 mm and greater, depending upon diameter, they can be produced in sizes from 3/8" to 4" dia. with varying thicknesses, precisely drilled holes, and special edge treatments.
