Chérubin d'Orléans
Chérubin d'Orléans was a French scientific instrument maker.
A Capucin father and distinguished physicist, Chérubin d'Orléans devoted himself to the study of optics and to vision-related problems, which he discussed in La dioptrique oculaire and La vision parfaite. He invented the first binocular telescope. He devised and may also have built a special type of eyepiece that replaced the lens with a short tube. Chérubin is also credited with producing models of the eyeball for studying the lens function of the eye. He also invented the stereo microscope, also called the dissecting microscope.
