Double Concave Lens

Double Concave Lens – Physics Optical Equipment

Spherical Double Concave Lenses are highly polished and well edged. Manufactured from plate Glass, optically true.  These lenses have negative focal lengths. These lenses diverge collated incident light and form virtual images, which are seen through the lens. They are often used to expand light or increase focal lengths in existing systems. They are used in laser beam expanders, optical character readers, viewers, and projection systems. Anti reflection coatings can be ordered as an option.

• High performance
• Long service life
• Reliable
