    Lux meter application

    Tips: How does the lux meter work?

    A lux meter, also known as a light meter, works by measuring the intensity of light in a given area. The device contains a photodiode or a photovoltaic cell that converts light energy into electrical energy. The photodiode or cell generates a voltage proportional to the intensity of light falling on its surface. This voltage is then amplified and measured by the device's circuitry, which displays the measurement in units of lux or foot-candles.

    Lux meters are used to measure the light intensity in various settings, such as photography, film, and video production, indoor and outdoor lighting, and in research applications. They are typically calibrated to measure the spectral sensitivity of the human eye, with different spectral responses for different types of meters.
