Vacuum Chambers for the Development of Electro-Optical Imaging Products

Electro-Optical Imaging Products have slowly become an irreplaceable part of our everyday lives. The simplest electro optical imaging product is the camera hardware and optics in our smart phones. The word “simplest” is actually used as a relative term here because our smart phone cameras are amazing technology. There are more sophisticated Electro-Optical systems which are build through the utilization of nanocrystals / nanomaterials to be deployed as a detection tool as a defense against chemical and biological threats.

Sophisticated Electro-Optical Systems have the ability to detect, track, and quantify a certain search criterion through spectral analysis of specific signatures. This is a very fascinating field of study.

Our client came to us because they had a need for a custom-made acrylic vacuum chamber. The vacuum chamber had to be cylindrical, placed horizontally on a table top. For Easy Access, both the left and the right side of the cylinder had to be accessible; they wanted two doors to be hinged and swinging out. On the doors, they needed a liquid feedthrough, we provided them with a 1/4 inch NPT feedthrough that is threaded on the inside and outside. This will enable them the connect a tube and run their gas or liquid from inside towards outside without compromising the vacuum inside the chamber during operations. Finally, they required two additional power feedthroughs to be present on each door.

The power feedthroughs were proprietary and provided by our client – for testing purposes we used button head screws with an O-Ring on the outside to seal off the feedthrough port hole. The doors are latched with a Destaco Style Latch. You can see that we started to run out of space, but we managed to place all components onto this chamber. “What’s that you say? You want a total of two chambers? Sure, well be happy to build as many as you need”

Acrylic Vacuum Chambers
Acrylic Vacuum Chambers are, as the name implies, vacuum chambers made from the Acrylic Polymer. There are several advantages to acrylic vacuum chambers the three main ones being 1. Fully Transparent, 2. Cost Effective, and 3. Versatile and Highly Customizable.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
Our Work: Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials
This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
