Request InfoEdmund Optics Inc.Hemispherical lenses made from sapphire are available from Edmund Optics Inc. The hard, tough sapphire material makes them suitable for use in severe environments, allowing them to withstand exposure to harsh chemicals and extreme temperatures. Sapphire has a high index of refraction and excellent broadband transmission characteristics. The half-ball lenses have a very short back focal length and a flat surface that facilitates easy mounting for use in endoscopes, microscopes, optical pickup devices and laser measurement systems.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueFemtosecond LaserThe Chromacity 920 laser source is designed for two-photon microscopy and the excitation of key fluorophores and calcium markers.
