Specialized Optics
Differentially Pumped
Specifically designed for extreme high vacuum applications such as Geochronology, MPF’s differentially
pumped windows employ all-metal, dual-seals having a port that accesses the resulting cavity between
the seals. The port can be attached to an auxiliary pump to extend the vacuum range beyond UHV.
This design has become the standard for geologists studying argon and helium dating.
Non-Magnetic
For optical applications involving strong magnetic fields or those that are exceedingly sensitive to
residual magnetism, MPF offers standard fused silica and extended range viewports made using nonmagnetic
mounting materials such as 316 LN stainless steel, CP titanium and aluminum.
Re-Entrant
MPF is now offering popular window designs, standard on re-entrant tubing designs. Available in sapphire,
fused silica and extended range viewport configurations, these designs are useful for coupling
complex lens assemblies such as cameras, telescopes and zoom lenses with applications where reach
into a vacuum system is important.
