Coated 6mm Dia Double Concave Lenses Optical Lenses For Laser
Double Concave Lenses
Double Concave Lenses are used in beam expansion, image reduction,
or light projection applications. These lenses are also ideal for
expanding the focal length of an optical system. Double Concave
Lenses, which have two concave surfaces, are Optical Lenses with
negative focal lengths.
GIAI Optics offers the world’s largest inventory of off-the-shelf
optical components, including a variety of standard or UV Fused
Silica Double Concave Lenses. Standard lenses are available in
several anti-reflection coating optics, including MgF2, VIS 0°,
VIS-NIR, NIR I, or NIR II, for optimal performance in the
Ultraviolet (UV), Visible, or Infrared (IR) regions. The UV Fused
Silica substrate offers excellent transmission characteristics with
high operating temperatures. UV Fused Silica Double Concave Lenses
are ideal for laser or imaging applications. An optional UV-AR
anti-reflection coating increases performance in the Ultraviolet
(UV) spectrum. GIAI Optics’ Double Concave Lenses are available in
a wide range of sizes or focal lengths.
Double-Concave (DCV) Lenses have two inward curved surfaces and a
negative focal length. They are used for image reduction and to
