Goniophotometry is the technique of measuring the angular distribution of light

A goniophotometer is a device that combines the functions of a photometer with those of a goniometric motion stage to create a single instrument. This process is also called goniophotometry. Specifically, the photometer is a photoelectric light meter that replicates the photopic spectrum sensitivity of the human eye by converting incoming illumination into an electric current.

The quantity of light emitted by the light source as well as its color (chromaticity, associated color temperature) may be measured by certain photometers, which also serve as colorimeters. The photometer or the colorimeter may be replaced with a spectroradiometer, or the spectroradiometers may be used in addition to the photometer or colorimeter.

What goniophotometer does?
In order to measure the light distribution of a light source, luminaire, self-luminous display, or surface in terms of luminous intensity or illuminance distribution, it is necessary to move a photometer or a goniometer to a precise location with an accurately specified geometry, which can be accomplished by using a goniophotometer. A conventional goniophotometer is composed of a mechanical device or robotic jib to support the luminaire to be measured, as well as a photometer or a spectroradiometer, and it enables the relative positions of the two instruments to be adjusted in order to create a spherical locus.

LSG-6000 goniophotometer
A photometer and a spectrometer may be used in conjunction with the LSG-6000 to function as a typical goniophotometer, or the LSG-6000 can be used as a high-quality goniospectradiometer. This makes it possible to measure all key performance parameters such as luminous intensity distribution curves, luminous flux, color coordinates, and even the color rendering index.

The newly designed luminous flux integrator, which is available as an optional device, enables the properties of lamps and luminaires to be determined when they are in their necessary burn position. In addition, measurements may be made more quickly and accurately as a result of the increased speed and accuracy.

Aside from that, LISUN offers a novel correction method for samples that are sensitive to their spatial location. For those looking for a low-maintenance measurement device with a small footprint, the LSG-6000, when combined with correction of the burning position, offers a legitimate alternative to a big and costly rotating mirror goniophotometer.

From LISUN, you can get the best goniophotometers for measurement purposes. As you will be pleased to know that the LISUN is one of the best manufacturers and suppliers of goniophotometers around the world.

In addition to the additional accessory choices, the goniometer’s basic version has a number of benefits over its competitors. Samples up to 1.6 m in diameter and weighing 50 kg may be mounted with relative ease because of the readily accessible stages in the process. Despite its substantial proportions, the LSG-6000 goniophotometer may nevertheless be accommodated in a laboratory with a typical ceiling height of 8 feet. Because the two servo motors are regulated in sync and have precise angle encoders, they can move at the same time with the least amount of vibration. Even while operating at a nominal load, the repeatability of the sample placement is less than 0.1°.
