Valuable background and reference information is contained on the websites listed below. These sites are very useful for understanding the principals and techniques that produce good confocal images.

The Nikon site demonstrates the affect of various parameters (e.g. pinhole, gain, brightness, scan speed) on the image quality coming from a confocal microscope.

The Laboratory of Optical and Computational Instrumentation has some very informative discussions and videos that illustrate the principals, benefits and shortcomings of confocal microscopy.

The U. of A Southwest Environment Health Sciences Center, has put together an award-winning microscopy site that contains infomation ranging from in depth "how-to's" to info for elementary schools. The discussion on the ethics of digital imaging is especially interesting for those just getting into the field.

The microscopy primer from Florida State University provides a wide range of discussions related to optical microscopy and imaging techniques.
