Overview: Singlemode fiber collimators are designed using high-index glass lenses to minimize aberration. They are primarily optimized for telecom applications but can be adapted for other wavelengths and uses. These collimators employ high-index plano-convex spherical lenses to effectively collimate light from singlemode fibers, featuring an angled flat side to reduce back reflection and a curved side for superior imaging.

Applications: These collimators are suitable for fiber-optic switches, DWDMs, fiber-optic attenuators, optical isolators, and more. Aspheric lenses can be used as an alternative for improved beam quality and reduced insertion loss.
