High Flatness Viewports

High Flatness Viewports

Torr Scientific offer high-flatness fused silica viewports in a range of sizes, ranging from λ/10 to λ/20 @ 632.8nm, using a bonding process as an alternative to vacuum brazing. Vacuum brazing viewports at high temperatures creates stress in the optic during the...
Max Planck Re-entrant Windows

Max Planck Re-entrant Windows

Torr recently designed, manufactured, tested and supplied four special 1700mm long re-entrant viewports to the Max-Planck Institute. These are being installed on the Wendelstein 7-X stellarator in Greifswald Germany as part of an ongoing system upgrade. Wendelstein...
Titanium fused silica and sapphire viewports at Torr Scientific.

Titanium fused silica and sapphire viewports at Torr Scientific.

The boffins in the technical department at Torr have been hard at work developing a range of vacuum brazed titanium viewports.Titanium has some advantages over stainless steel, including lighter weight & being truly non-magnetic, the optics are vacuum brazed into...
CERN Windows

CERN Windows

Torr were recently commissioned to produce some special windows for CERN.  The windows were welded into a pre-machined body and then subjected to a high-pressure test. The application for the windows is the Beam-Gas-Curtain instrument (wepb16.pdf (cern.ch)). The LHC...
KBr viewports and Parylene coating

KBr viewports and Parylene coating

Torr Scientific offer a range of Infrared vacuum windows using a range of materials.  One such material is potassium bromide (KBr).  Under standard conditions KBr is a white crystalline powder, but it can also be manufactured in optical blanks which can be ground and...
Re-Entrant Viewports

Re-Entrant Viewports

Torr have manufactured customised re-entrant viewports in a wide range of sizes, lengths, mounting flanges, and optical materials.The re-entrant viewport is used to insert a device directly into the vacuum system whilst it remains at atmospheric pressure.This allows...
Ultra-thin Optical diamond viewport supplied to MaxIV

Ultra-thin Optical diamond viewport supplied to MaxIV

Torr Scientific recently delivered a very thin optical quality diamond viewport to MAXIV in Lund, Sweden.The diamond is 100um thick and has a clear view diameter of 4mm, it is vacuum brazed into a custom 316LN DN40CF flange.It will be installed between the...
Rubidium Dosing Cell

Rubidium Dosing Cell

The attached picture shows a rubidium vacuum cell that was recently manufactured in the glass shop at Torr scientific. It is shown in the upside down position.Once the cell is placed under vacuum, a small steel bar (which lives in the small side port) will be moved...
Viewport Shutters

Viewport Shutters

In addition to offering viewports, Torr Scientific has a range of viewport shutters. Designed to be mounted between the viewport and the chamber flange, the shutter has a flap that can be rotated to cover the vacuum face of the viewport optic. This will protect the...
Brewster Windows

Brewster Windows

A Brewster window is an optic placed in the path of an optical beam at a special angle, this angle allows p-polarised light to enter and exit the window almost without any transmission losses. Any s-polarised light is reflected and this produces a fully polarised...
Microspike Biosensor Coating

Microspike Biosensor Coating

Microspike biosensors are minimally invasive sensors which can be used to measure metabolites, biomarkers and drugs in the interstitial fluid. The microspike substrate material is polycarbonate. The metallic electrodes can be functionalised with a variety of coatings....
Indium Tin Oxide

Indium Tin Oxide

Indium tin oxide (ITO) is an unusual material: it can be both electrically conductive and optically transparent. Depending on the oxygen content, it can either be described as a ceramic or an alloy. In vacuum applications, ITO is applied to optical components to allow...
