Atomic-emission spectrometer EMAS-200D (EMAS-1000) and UniChrom n-Vision

Producer: JSC "Spectroscopic Systems"

Equipped with the UniChrom n-VisiON software

System incorporates multi-monochromator design.
I.e. for specified analytical task the crate (picture at the left) is filled with up-to 5 monochromators fixed at analytical wavelength ranges. This makes system less affected by environmental conditions, since fixed monochromators are very stable.

Every monochromator is equipped by 3645-element CCD sensor, so entire system represent a virtual CCD sensor from 3645 to 18225-element linear detector.

Every region monochromator has its own fiber-optic light entrance. All the fibers are bundled inside the spark-chamber and adjusted to look at electrodes.

System is controlled by ARM9-family (ns9750) embedded computer running Linux (2.6 kernel). External control made through TCP/IP 100-Base T ethernet connection. System provides up to 10 spectra per second, depending on exposition time. Ethernet connection (transformer-decoupled) is less sensible to EM noise impact (generally arc and spark generators produce EMF).
