A photometer is an instrument used to measure light intensity, therefore, the eclipsing binaries are best studied as we observe a periodic decrease of sunlight intensity as one member of the binary passes in front of the other.
The difference between the photometer and the spectrometer is a matter of complexity. Both are used to measure color absorbency quantitatively, but photometers are much simpler in design, having fewer parts, and as such are less expensive and easier to obtain. They're usually not quite as detailed in results as a spectrometer, however.

Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.Your eyes are instrumentstha measure EM radiation between 300 and 700 microns. We call this type of EM radiation "visible light." Other detectors of EM radiation ar CCD chips in digital cameras, and IR detectors in appliances with rerote controls.spectroscope?
Photometer is an equipment commonly used on a clinical laboratory. It has different kinds which can do certain jobs like testing blood samples. The examples of photometer used in a clinical laboratory are the flame photometer and Hemoglobin Photometer.

A luminometer, also known as a photometer, is used to to measure light intensity.

A colorimeter is a scientific instrument that measures the intensity of light passing through a pure sample. In biology, colorimeters are used to monitor the growth of cultures. As the culture grows, the growing medium becomes more cloudy and absorbs more light.

spectrophotometer
Yes. A photometer is an instrument that measures the intensity of the incoming light and quantifies it into numerical data. A photometer is a light sensitive device and measure the power of light.
