Custom Domed Tubulation

Custom Domed Tubulation

Custom glass fabrications Several years ago, Torr Scientific extended its vacuum window processing capabilities to include production of glass‑to‑metal seals. We have our own glass shop, which allows further development of the wide range of ultra‑high vacuum optical...
X-Ray Anode Refurbishments

X-Ray Anode Refurbishments

X-rays were a discovery by the German scientist Wilhelm Röntgen, who called them X-rays because their nature was unknown. When an energetic charged particle is deflected by another charged particle (typically an electron by an atomic nucleus), the resultant...
Fused Silica vs Natural Z-Cut Quartz

Fused Silica vs Natural Z-Cut Quartz

Natural z-cut quartz and fused silica are optical materials that are colourless and transparent to visible light. Both are nominally chemically identical, both being silicon dioxde (SiO2), also known as silica. They are both reasonably tough materials and have good...
Custom Atom Trap Chamber

Custom Atom Trap Chamber

In atomic, molecular, and optical physics, a magneto-optical trap (MOT) is an apparatus which uses laser cooling and a spatially-varying magnetic field to create a trap which can produce samples of cold, neutral atoms. A MOT is formed from the intersection of a weak,...
Custom Glass Cell

Custom Glass Cell

Torr recently manufactured a custom glass quantum cell for one of our customers. There has been a recent shift in focus towards quantum system packaging to enable academic experiments to become “in-field” prototype systems. In many cases, the often bulky...
KRS-5 Bonded Window

KRS-5 Bonded Window

Torr recently manufactured a bonded KRS-5 viewport for one of our customers. KRS-5 is the short name for thallium bromo-iodide (TlBr42I58), it is one of the family of thallium halides.   The KRS prefix is an abbreviation of “Kristalle aus dem...
O-Ring Sealed ISO Flanges

O-Ring Sealed ISO Flanges

  Large view diameter viewports become uneconomic to manufacture using the traditional vacuum brazing or induction sealing techniques. It is still possible however to manufacture them using FKM O-rings to make the vacuum seal. An external bolted ring is used to...
Ulm University – Brewster Window Installation

Ulm University – Brewster Window Installation

Torr Scientific recently supplied the Institute for Surface Chemistry and Catalysis based at Ulm University in Germany with a DN40CF demountable fused silica Brewster vacuum window. The demountable window uses FKM O-rings to make the vacuum seal, this allows the fused...
Silicon Viewport

Silicon Viewport

Silicon can be used as a vacuum window material, it has good optical properties in the mid-IR range which is useful for many imaging, biomedical and military applications. The material has high thermal conductivity and low density, making it suitable for laser...
Differentially Pumped Viewports

Differentially Pumped Viewports

Differentially pumped viewports are a useful way of introducing optical materials that cannot be sealed with more traditional methods to a vacuum system as a window. The optic sits on a pair of O-rings, the interspace between the O-rings is pumped by an auxiliary...
Brewster Window Case Study

Brewster Window Case Study

Torr Scientific recently manufactured a demountable brewster window for one of our customers at the Institute for Surface Chemistry and Catalysis (IOK) located in the University of Ulm in Germany.The window has a demountable fused silica optic, which allows it to be...
Brewster Window Theory

Brewster Window Theory

Get used to Brewster Polarized light, or more strictly plane-polarized light, has its electric field vibrating partially or totally in a particular direction. Non‑polarized light can be thought of as having an electric field that vibrates equally in all possible...
