The P-2000 multi-option polarimeter from JASCO (Easton, MD) is designed to be customizable with options to handle a researcher’s initial requirements and then upgraded at a later date. The unit can operate via a PC with Windows® software or by JASCO’s handheld controller (iRM). The device has a range of light sources: tungsten-halogen, sodium, or mercury lamps. Up to two sources can be simultaneously installed, from the UV-V region (254 nm) to the NIR region (880 nm). Sample temperature is available at ±0.1°C accuracy.
