Wide angle attachment for fundus cameras.
A simple and inexpensive method for increasing the angle of view of existing fundus cameras used for fluorescein angiography is described. The addition of a concavo-convex positive lens extends the usefulness of the camera and contributes to the efficiency of diagnosis.
Design of a wide-angle ophthalmoscope.
A prototype of a wide-angle ophthalmoscope that will allow viewing the entire retina in a single image is described. The principles determining the design of a wide-angle ophthalmoscope are discussed. Photographs are presented, taken in experimental animals, of the aerial image of the fundus as visualized with this instrument.
Strategies for glass based photonic system integration
There is a clear tendency to integrate more and more opto-electronic and micro-optical components like optical fibers, laser diodes, modulators, isolators, beam-splitting components and micro lenses in also increasingly dense and complex assemblies. The paper will discuss thin glass as a very promising base material for that kind of photonic packaging on interposer and board level including optical interconnection using fibers.
