This digital spectrophotometer is used for quantitative investigations of emission and absorption spectra and transmission curves, and for measurements related to calorimetry and chemical kinetics. Based on the Czerny-Turner principle, this device permits simultaneous, real-time recording and analysis of the entire visible range from 380 nm - 830 nm in conjunction with the user-friendly measurement and evaluation software. Light recorded by means of an optical fiber and projected on a CCD detector via two mirrors and a reflection grating. Includes an absorption module with cell and slide holders for disposable cells and color filters, a software program and various connecting cables. Spectral range: 380 - 830 nanometer. Wavelength accuracy: 0.25 nanometer. Resolution: 1 nanometer. Transmission: 0 percent - 100 percent. Resolution: 0.1 percent. Absorption: 0 percent - 100 percent. Resolution: 0.1 percent.
