What is Goniophotometer?

It is a device used to measure the light emitted by a light source in different directions. It is critical in photometry to describe the angular distribution of light, which is required to understand how light is distributed or directed by a luminaire (light fixture).

Types of Goniophotometer

There are three types of gonio photo meter –

1. Type A: It is measures luminous intensity which is distribution in a single plane.
2. Type B: Measures in two planes, which are commonly employed in vehicle and roadway lighting.
3. Type C: The most popular form, measuring in many planes, is frequently used for general lighting.

Applications of Gonio Photometer

Here are some uses of this type of photometer –

1. Used for designing and optimizing lighting in buildings, streets, and vehicles.
2. Ensures that lighting products meet all regulatory and safety requirements.
3. Used in laboratories to investigate light behavior and qualities.
