Attaching Fiber Optics to CCD/CMOS Sensors

With the use of CCD/CMOS area cameras or line scan cameras, there must be usually projected an image onto the CCD sensor. Beside conventional lenses also fiber optics are used for this. These consist of up to 6µm of thin glass fibers, which are as bundle able to transfer an image. Conventional lenses transfer about 3%-5% of the incoming light to the sensor, a fiber optic however up to 70%.
In order to attach a fiber glass optic on a CCD sensor, the glass cover is removed and the CCD chip is measured. Then the fiber optic becomes polished, so that it rests flat upon the chip and can be attached to the housing. When using fibers with 6µm diameter, the resolution of a sensor with e.g. 14µm pixel size is hardly impaired.
We are able to attach a fiber optic to all image sensors, which can be delivered without glass cover, or where we can remove the glass cover.
