Extended information:

Single-lens reflex viewer. p>Single Lens Reflex Camera (abbreviated as SLR camera) is also known as SLR camera. It is a camera that uses a single lens, and the light shines through this lens to the reflector, and the view is taken by reflection.

The term "single lens" refers to the use of a single lens for the photographic exposure and viewfinder paths***, unlike side-axis or dual-lens reflex cameras, which have separate lenses for the viewfinder path.

"Reflective" means that a flat reflector in the camera separates the two light paths: when framing, the reflector falls down, reflecting the light from the lens to the pentaprism, and then to the viewfinder window; when shooting, the reflector lifts up quickly, so that the light can reach the film or the sensor CMOS or CCD.
