👉 In physics and optics, a slitted lens is a device that allows light to pass through an aperture (a narrow opening) in a slit. The slits are typically made of transparent materials like glass or plastic, so they act as openings for light to enter the optical path. This technique is used in various applications such as photography, engineering, and telecommunications. The term "slitted" refers to the fact that the aperture (the narrow opening) on a slitted lens allows light to pass
