Monochromator Optics Air Purge
(Part number G8000-68001)
The monochromator is a precision mechanical device and its
continued stable and reproducible operation relies on clean
corrosion free surfaces.
The Monochromator Optics Air Purge accessory is designed to
minimize the ingress of particles and corrosive vapors, commonly
encountered in the typical laboratory, into the monochromator by
providing a continuous flow of clean, dry, oil-free and dust free air
into the monochromator assembly. The use of this accessory provides
additional protection for your instrument.
