After years of research and development Raytex has developed a unique method to improve on the age-old technology of the pinhole. Technical perfection is achieved by having an extreme thin foil to allow the light beams to pass with minimal defraction. The difference is best explained by imagining light rays passing trough a tube and light rays passing trough a hole without depth.

It is of course not possible to produce a hole without depth in practice, but the thinner the foil the better the result.

With the "Raytex Sandwich Foil Holder" system the Pinhole Foil is held perfectly flat and protected between two finely machined discs. Like meat in the sandwich. This allows the use of extremely thin foil, even paper.

To make a pinhole in very thin foil is also much easyer than in thick foil. Up to now the use of very thin foil was restricted by mechanical limitations. (The foil was very sensitive to demage. The Raytex system protects the foil from demage, especially the optics with a solid shutter in front of the pinhole.
