Lenses are well suited for a wide variety of applications, including use in fibre communications equipment, endoscopes, microscopes, optical pickup devices and laser measurement systems.
Edmund Optics is offering hemispherical lenses made from sapphire.
The lenses are well suited for a wide variety of applications, including use in fibre communications equipment, endoscopes, microscopes, optical pickup devices and laser measurement systems.
The lenses are attractive for use in severe environments because they are made from sapphire.
This hard, tough material is known for its ability to withstand exposure to harsh chemicals and extreme temperatures.
Sapphire also features a high index of refraction and excellent broadband transmission characteristics.
These half-ball lenses offer a very short back focal length, along with a flat surface that facilitates easy mounting.
