About machine

The Evolution 300 optical design includes a long lifetime xenon flash lamp and extended wavelength-range silicon photodiode detectors. This system is an excellent choice for routine and research laboratories in the Life Science and Pharmaceutical markets.Optics : Quartz overcoated optics for long-lasting reflectivity and cleaning without damaging the optical surface.Mercury: Lamp Primary reference standard, allows seamless validation and calibration of the instrument light Source: Xenon flash lamp is only on when taking measurements extending its lifetime Slit Mechanism: Photo-etched slits for greater accuracy. Stepper-motor driven slit drive with intelligent optimization. Grating : 1200 lines/mm, 240 nm blazed, holographic grating, for exceptional stray light performance. Detectors: Silicon photodiodes for extended wavelength range to 1100 nm. Chassis: Rigid, cast-aluminum base with optical mounts bolted directly onto the base provides superior system stability and reliable results. Micrometer Monochromator Drive with Sliding Coupling: Provides excellent accuracy, reproducibility and minimizes temperature effects.
