PL measurement is a non-contact, non-destructive method for evaluating LED characteristics by imaging the light emitted from a LED by photoexcitation.
MiNY PL is a unique two-dimensional imaging technology that calculates the emission wavelength in a wafer plane at once without measuring the spectrum using a spectroscope. Compared to spot measurement using a spectroscope, in-plane emission wavelength can be obtained at high speed.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
