Sanmak Optical Lab
Sanmak import equipment from German,high standard quality,like LCG goniophotometer to test our products 
for measurement of the light emitted from an object at different angles.We could test our lights and are sure
to meet customers’ need.
 
A Goniophotometer is a device used for measurement of the light emitted from an object at different angles.
The use of goniophotometers has been increasing in recent years with the introduction of LED-light sources,
which are mostly directed light sources, where the spatial distribution of light is not homogeneous.
If a light source is homogeneous in its distribution of light, it is called a Lambertian source.
Due to strict regulations, the spatial distribution of light is of high importance to automotive lighting and its design.
 
The luminous intensity distribution describes a fundamental characteristic of luminaires.
A goniophotometer is generally used to measure this property. The setup comprises a mechanical
goniophotometer with a horizontal and vertical axis for rotating the test sample and a photometer for
measuring the luminous intensity over a given distance.
