Fiberoptic coupling

In most cases of CCD applications, the incoming light is transferred to the CCD through a lens. In some situations, the use of fiber optic elements is better because the light collecting efficiency is much higher. Fiber optics are used in low light level applications to couple the light from scintillator screens, image intensifiers or streak tubes to a CCD or CMOS sensor. The photons are guided in the fibers direct to the sensitive pixels. The fiber optic coupling allows a much better transfer efficiency of the photons to the sensor pixel than a normal lens system. For example, a 1:1 fiber optic plate instead of an f/1,2 lens reach 10 times higher efficiency. It is possible to couple to the most front-illuminated CCDs and it is possible to couple to some back-thinned CCDs. It is possible to couple with 1:1 fiber optic plates and with fiber optic tapers. The maximum reduction ratio is 6:1 and the maximum available outer diameter of the large taper side is 165 mm.

Each coupling has its very individual requirements. We will be pleased to find the best-suited strategy for your specific project.
