Collimatinglens

High-numerical-aperture aspherical lenses are used for precise collimation and maximum light throughput. The collimator features adjustable focus from ~100mm to infinity. Various lightguide ferrule diameters are supported. Customization is available for other ferrule diameters.

Lightguide collimators are used to either couple light from free space into a lightguide or collimate light from a lightguide to form a collimated (parallel) optical beam. Lightguide collimators are key components with numerous applications. For example, a lightguide collimator can project light from a lightguide into a uniform spot in free space.

Ferrule length must be at least 15mm.

The full field of view (FOV) or full divergence angle can be calculated as FOV = 2atan(D/2f), where D is the lightguide core diameter and f is the focal length of the lens. Alternatively, the linear field of view on an object placed at a distance L away from the collimator is D(L/f).
