A mini-spectrometer is used to perform spectral measurement and inspect LEDs or the like.
White light interferometry is used to measure the spectrum peak count, film refractive index, and film thickness from the light incident angle.
Plastic screening is performed by using the fact that when near infrared light is directed at plastic, the wavelengths that are absorbed varies depending on the material.
Emission spectrum of fluorescent materials, such as fluorescent lamp and organic EL devices, is measured.
Mini-spectrometers are used in environmental analysis of water, soil, and the like.

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.
