Integrating sphere measurements

A method used to assess the total luminous output of a light source or a lighting installation. It involves placing the light source inside a sphere coated with BoSo4 a highly reflective material. When the light source is switched on, the light is reflected around the sphere and integrated or measured from all directions. This provides a comprehensive understanding of how much light the source emits in all directions. Integrating sphere measurements are useful for evaluating overall light quality and efficiency, which is important in fields such as lighting technology and photometry.

Goniophotometer measurements

A measuring instrument used to measure and analyse the light intensity distribution of a light source or luminaire in different directions.

This measurement is important in order to understand how light spreads at various angles from a light source.

The measurement is particularly useful in the lighting industry, where it is important to design luminaires that distribute light so it meets specific lighting requirements.

Ultraviolet light measurements

Involves assessing the amount of ultraviolet light, a type of electromagnetic radiation with a short wavelength. UV light lies outside the visible spectrum that our eyes can normally perceive.

Measuring UV light is important in various applications, such as disinfection of viruses and bacteria or in industrial lighting to evaluate the emission of UV light from light sources. These measurements help to understand and control UV light exposure, which can have implications for health and technological processes.
