General Optics
C-Lens & D-Lens
Build low insertion loss fiberoptic components – including switches, isolators, circulators, DWDMs, fiber amplifiers, and more – with these miniaturized optics.
These are miniature optics for collimating and coupling fiberoptics, or in-coupling light from laser or LED sources. They use spherical surfaces and offer lower cost and insertion loss, and longer working distances, than gradient index (GRIN) lenses.
