Description: Lot of 2 Biconcave LensesAlso known as bi-concave or double concave lens. These are negative focal length lenses, otherwise referred to as diverging or defocusing lenses.On their own they only form virtual images, seen through the lens.They are symmetrical, with equal radii on both sides. They are often used to expand light or increase focal length in an optical system, such as with a Barlow "lens." They are used to diverge a collimated beam to form a virtual focus in Galilean-type beam expanders. Some applications include laser beam expanders, optical character readers, viewers, and projection systems. These are new, but may have indications of having been shuffled about. Their exact glass type and optical performance is unknown. There may be some small chips around the ground edge or other minor imperfections.
