LED Luminescent Spectrum

LED Luminescent Spectrum   Spectrum is the relative distribution of wavelength and light intensity. The spectrum of LED is generally monochromatic LED, such as blue LED with a peak wavelength of 470nm, with shorter peak wavelength ultraviolet area and with longer peak wavelength green areas as the determination limitation of light intensity.

Integrating Sphere Development

Integrating Sphere Development   Integrating Sphere is used for flux measurement, which can make test result more reliable. Integrating Sphere can reduce the measurement error caused by the shape of light, divergence angle and responsiveness difference in different location on detector. Let us learn more details about the development of Integrating Sphere manufacture technology. Picture […]
