Brief Introduction of colorimeter and color difference

Concept of colorimeter: Colorimeter is an instrument used to measure the color difference of objects. It can also be called chroma meter, and pigment colorimeter. Classification of colorimeter: According to different working principles, colorimeter can be divided into two categories: photoelectric integral colorimeters and spectroscopic colorimeters. Photoelectric integral colorimeter is commonly ...

Explain basics of integrating sphere

The inside of an integrating sphere is hollow and coated with a highly reflective white material. One may use such led testing equipment to determine the overall luminous flux of a lamp or the laser’s output power. You may consider integrating spheres as a hybrid between cosine correctors and lenses-only optics. To function, instruments like spectroradiometers need to be linked to a calibrat...

LED luminaires measurement by spectroradiometer integrating sphere system

What is spectroradiometer? A spectroradiometer may determine the wavelength and intensity of light from a source. It is also called the led integrating sphere. Spectrometers LPCE-3 can collect the whole spectrum with a single acquisition because they separate the wavelengths depending on where the light strikes the detector array. In most spectrometers, the detector’s sensitivity to each wav...

Explain the goniophotometer and how does it differ from integrating sphere?

A LM-79 goniophotometer is an instrument for measuring the light reflected off an object at various viewing angles. It is somewhat considered like integrating sphere spectrophotometer. Most recently used LED-light sources are usually directed light sources with a non-uniform spatial distribution of light, necessitating the employment of goniophotometers. A Lambertian source is one whose light is d...
