Rheinberg filters allow you to add brilliant contrasting colors to your microscope viewing and photography in a very inexpensive way. Most microscopic specimens are clear, and since microscopes use light, it passes through these mostly transparent objects. From microorganisms in a pond, to ancient micro fossils called diatoms, allergy causing pollen spores in the air, crystals like sugar and salt, and many other interesting specimensthey are all clear when viewed under a microscope.
So, these very beautiful things are difficult to see against a white background of pure light passing from the illuminator through your eyepiece.
The only way to see these things is by using contrast. This booklet is about a special method of creating contrast by Optical Staining. That's a fancy way of saying we color the light, selectively. It's like dyeing clothwithout the chemicals. This 39 page E-book with dozens of instructional photos, teaches you the Rheinberg method using tools and materials easily obtained at your local office supply store.
