What is "reflectometer"

n. An instrument used to measure the reflectance of a surface.

n. a meter that measures the reflectance of a surface

Some scientific instruments commonly designated Reflectometer are:

• Vector Network Analyser (VNA)
• Spectrophotometer: in optics, an instrument for measuring the reflectivity or reflectance of reflecting surfaces
• Optical time domain reflectometer
• Reflectometer (electronics): In electronics, a directional coupler containing matched calibrated detectors in both arms of the auxiliary line, or a pair of single-detector couplers oriented so as to measure the electrical power flowing in both directions in the main line
• Time-domain reflectometer
