digital spectrometer ld with absorption chamber

The Digital Spectrometer LD with Absorption Chamber is well suited for quantitative analysis of emission and absorption spectra, for recording transmission curves and performing measurements in calorimetry and kinetics. Incident light from a fibre-optic cable is dispersed into a spectrum by a Czerny-Turner monochromator and projected from there onto a CCD detector.

User-friendly measurement and evaluation software enable simultaneous recording and analysis in real-time, while the built-in software for Windows 2000/XP/Vista/7/8 32- and 64-bit versions starts running as soon as the sensor is connected to the computer via a USB cable. Includes plug-in power supply and holder for fibre-optic cable.

The absorption chamber is a multi-functional module with a built-in light source and a chemical-resistant metal casing. It is ideal for recording transmission or absorption measurements using 4ml cells, objects in slide format or objects in coin format.
