rangefinder
A rangefinder is a specialized tool used to determine the distance between the observer and a target. In modern daily usage, this most commonly refers to handheld laser devices used in sports like golf or for outdoor activities like hunting, where precision is required to choose the correct equipment or aim.
In the context of photography, a rangefinder refers to a specific type of camera mechanism. Unlike a Single-Lens Reflex (SLR) camera, a rangefinder camera uses a separate window to help the photographer focus by aligning two overlapping images into one.
Historically and in military contexts, rangefinders were large, complex optical instruments used to calculate the distance to enemy ships or artillery targets. While these have been replaced by radar and digital systems, the term remains the standard descriptor for any device performing this specific measurement function.
