The Pinhole Configuration Cards have been designed to explore the basic fundamentals of the creation of images – concepts of focal length, focal ratio, image and object size. The “A” card has two pinholes with different diameters, and the “B” card has three pinholes of the same diameter. These Pinhole Configuration Cards are a component of our Introductory Optical System (#92-7700), and are used in conjunction with the Single Lens Holder. Please note: Lens holder sold separately.
