Advanced Spectroscopy – How It Works

The JASCO® V770 Spectrometer utilizes grating diffraction to disperse light into a continuous spectrum based on wavelength. Monochromatic light is then selected using a slit mechanism, allowing for the separation of specific wavelengths. This monochromatic light is split into two equal-intensity beams. One beam passes through the sample while the other is used as a reference. By comparing the intensities of these beams, the transmittance ratio of the sample is calculated. The system can generate both a transmission spectrum and an absorption spectrum, offering critical insights into the material's optical properties.

Dual Light Sources for Full Spectrum Analysis

The system is equipped with a Deuterium lamp for UV/VIS measurements (190 ~ 350 nm) and a Halogen
lamp for VIS/NIR measurements (330 ~ 2700 nm), covering a broad range of wavelengths. This dual-light source setup ensures the accurate measurement of light transmission and absorption across the full spectrum
