ball lens
Numerical aperture of ball lenses is proportional to their refractive index. These lenses are used in visible and near infrared spectrum. The ball lenses could be equatorially ground relative to direction of optical axis to facilitate packaging and orient AR coating. The round cross-section of these lenses results in the large field of view and simple, cost-effective alignment where most of the positioning errors result in simple focusing errors. These lenses can be used as fiber-optics collimators. In order to accommodate different fiber-arrays pitch, the edge of the lens may be ground to a desired width.

Optical Windows
Optical windows are used for protecting fragile optical components inside an assembly. Substrate material is BK7, B270, Float Glass, Borosilicate, or UV Fused Silica.
