Midplane Cavity Housings: VH 6030

We can optimize this portable and customizable cavity/housing design to your specific application needs.

Our understanding of the finite element modeling of temperature effects on a wide variety of cavity/housing combinations, and our skill in their build, allows us to capitalize on the flexibility inherent in the vertical mounting of midplane cavities. From dual stage temperature stabilization to fiber coupled, transportable, and hermetically sealed vacuum housings, we can create the exact solution you require in a fraction of the time you would need to design it.
