How can you use Type C Goniophotometer to measure lighting sources

A goniophotometer is a tool used to determine an instrument’s luminosity. It does this by evaluating the 3D curve of the light intensity distribution. LISUN’s goniophotometer- LSG 6000 is typically used to measure the radiance or brightness of equipment. It gauges how bright indoor spotlights, street lamps, or car lights are. It assesses how evenly the light intensity is distributed in...

EMI test equipment setup you need to know about

Electronic noise, also known as electromagnetic interference, impedes cable communications and weakens their integrity. Typically, machinery and motors that emit electromagnetic radiation serve as EMI receiver generators. Conducted interference and radiated interference are the two forms of EMI receivers. The coupling of signals from one electrical network to another electrical network over a con...

How to use the LISUN integrating sphere for LED light measurements

Integrating sphere, also known as luminous sphere and photometric sphere, is a hollow and complete spherical shell. The integrating sphere is mostly made of metal materials, and the inner wall is coated with a white high diffuse reflection layer (usually magnesium oxide or barium sulfate), and all points on the inner wall of the sphere diffuse evenly. There are also integrating spheres made of hig...

Benefits and Fundamentals of an Integrating Sphere

Integrating Spheres have a specified sensitivity to beam size and beam divergence. An integrating sphere is an optical instrument for capturing a light beam and measuring the power in the beam under specific conditions. It is also known as the Ulbricht Sphere and consists of a hollow spherical cavity. The inner surface is covered with a diffuse white reflective coating and the entrance and exit p...
