Fiber-optic cable mounted radiance collector with sapphire optics

Radiance collectors are sampling optics designed to collect ultraviolet, visible, and infrared light in a small cone.  The angular acceptance cone of the collector depends on the diameter of the fiber optic cable attached to the sensor and the index of refraction of the media being measured. HOBI Labs radiance collectors have a 3.2 degree field of view in air when used with 200-micron fibers.  With a 600-micron fiber, this increases to 9.4 degrees.  The Radiance collector connects to fiber optics with a SMA-905 connector and o-ring seal.  Designed for underwater use with HOBI Labs fiber optic cables, but can be used with any SMA-905 terminated cable.
