Light testing

Light testing. Long-exposure photograph showing a gonio-photometer (goniometer for short) at the Osram Sylvania Light Research Laboratory, USA. This testing device obtains measurements of light luminance over several wavelengths. The light bulb is placed at the centre of tha goniometer and its light is reflected onto a mirror located at the end of a rotating arm. Light from the mirror is in turn directed onto a sensor. The rotating arm is necessary to record light output over a large range of angles. The goniometer enables researchers to test new energy efficient long- life light bulbs

EDITORS COMMENTS
This print captures a moment of light testing at the renowned Osram Sylvania Light Research Laboratory in the United States. In this long-exposure photograph, we witness a fascinating piece of technology known as a gonio-photometer, or goniometer for short, being operated by a skilled male researcher. The purpose of this intricate device is to measure light luminance across various wavelengths. Positioned at the center of the goniometer is a bright and efficient light bulb, which emits its radiance onto a mirror located at the end of a rotating arm. The mirror then redirects the reflected light onto an advanced sensor for analysis. To ensure accurate readings over different angles, the rotating arm plays an essential role in recording the output of light. This ingenious engineering test enables researchers to evaluate new energy-efficient and long-lasting light bulbs thoroughly. Within this domestic laboratory setting, where cutting-edge technology meets scientific exploration, scientists delve into physics and efficiency to develop lighting solutions that are both environmentally friendly and economically viable. The Osram Sylvania Light Research Laboratory stands as a beacon of innovation in North America's technological landscape. This mesmerizing image from Science Photo Library not only showcases state-of-the-art equipment but also embodies humanity's relentless pursuit to illuminate our world with sustainable brilliance.
