Which of the following meters measures the light coming directly from a source?

An incident meter measures the light coming directly from a source. This type of meter is used to measure the intensity of light that falls on a subject or area, as opposed to a reflected meter, which measures light that bounces off a surface. Incident light meters provide accurate readings of the lighting conditions, which is essential for calibrating AV systems. According to Axis documentation, using an incident meter is crucial for obtaining precise light measurements in AV setups.
