Optical Caliper

An optical caliper is a measurement device that uses light—usually a laser or a bright LED—to determine the size or distance of objects with high precision. Instead of traditional mechanical parts, it employs optical sensors and systems to detect the position or dimensions of an object. When the light interacts with the object or passes through specific components, the device calculates measurements based on light behavior, like reflection or diffraction. Optical calipers are commonly used in engineering and manufacturing for accurate, non-contact measurements, making them ideal for delicate or small objects where traditional tools might be less effective.
