Instrument LED light source uniformity and stability
Spectrum. Depending on the band I. ED light intensity set the appropriate drive current, can be in a certain wavelength range uniform flat light source spectrum. On this basis,[link widoczny dla zalogowanych], the stability of the optical source. Traditional near infrared spectroscopy is generally optimized by the light source to improve the stability of the circuit. In this study,[link widoczny dla zalogowanych], in addition to precision current source to provide current drive I. ED stable luminescence,[link widoczny dla zalogowanych], and dual optical methods to further reduce the light stability of the detection system. Experimental results show that the uniformity and stability of the system can achieve very high precision,[link widoczny dla zalogowanych], portable infrared spectrometer designed to meet the requirements.
