SF11 Spherical Lens
 
These lenses are manufactured from SF11 for VIS and NIR applications and are supplied coated or uncoated. SF11 is generally used instead of BK7 to minimize aberrations from short focal length lenses. The higher refractive index provides for a less-steeply angled surface and a better transmitted wavefront.
Standard narrowband "V"-coat antireflection coatings are available, see ordering section below. When used to focus a collimated beam, the light should be incident on the curved surface of the lens. SF11 lenses may be combined with other lenses to form complex systems.
To order an antireflection coated lens the wavelength in nanometers should be appended to the part number.
Please call your Shanghai Optics sales engineer for pricing and delivery details.
