Sapphire lens
Due to sapphire has high transmission from 150nm up to around 5µm therefore ideal for UV, Visible and IR applications. Sapphire lenses have excellent mechanical strength and hardness. With sapphire having superb thermal and chemical resistance and being scratch resistant, sapphire is a perfect choice for lens applications. Sapphire is inert and resistant to attack from most processing environments, such as hydrofluoric acid.
We Ricun supply a range of sapphire lens solutions and offer plano convex, biconvex and concave sapphire lens solutions. Our sapphire lenses can also be antireflective coated to increase efficiency in UV and IR applications. Sapphire grades we offer are Random, C-Cut, Z-Cut and fluorescence free sapphire.
Configurations such as plano/plano, plano/convex or concave, concave/convex, rod lens can be customized, tell us your requirment or send us the drawing, we will reply you within 24 hours.
