Photonwares’ miniature OCT fiber probe is the ideal optical imaging solution offering high resolution and high sensitivity in a miniature format. Based on Photonwares’ patented beam shaping technology, a high quality lens is uniquely formed directly at the fiber tip that focuses to a small beam spot.

The OCT fiber probe features optical efficiency that is more than five times greater than a fiber coupled to a conventional GRIN lens collimator. Photonwares’ fused lens technology eliminates the need for fiber-to-lens alignment and can be made in small diameters compatible with all existing fibers.

Custom-built side-firing probes are also available.
