Torr Scientific manufactures a range of competitively priced UHV viewports in CF, ISO or KF formats including a variety of coatings to enhance performance. Materials include Kodial (borosilicate glass), Quartz, Sapphire, MgF2, BaF2, CaF2, ZnSe, ZnS 'Cleartran', Ge, Si and Lead Glass. Full transmission, dimensional, optical and temperature specifications can be viewed on the viewport datasheets and standard price list. Custom designed viewports can be quoted on request.

Torr Scientific Ltd offers a range of optics in Fused Silica, Sapphire, Magnesium Fluoride, Barium Fluoride, Lithium Fluoride, Calcium Fluoride, Zinc Selenide and CVD Diamond. Sizes typically range from 18mm to 144mm diameters. Flatness and scratch & dig specification vary with material and can be quoted to meet customer specifications. Standard optics used in TSL viewports are available from stock. Please contact TSL with your optic requirements.

Torr Scientific is launching a range of ceramic breaks and ceramic feedthroughs. The ceramic to metal seals, processed in TSL's recently acquired vacuum furnace, are fully UHV compatible and bakeable to 450 degrees C. Data sheets will be added to the website soon (click here for preliminary flyer!). Products will include breaks and feedthroughs with CF and KF flanges.

Please contact TSL with details of any ceramic to metal seal requirements to your specifications.

Torr Scientific is proud to have been appointed the European agent for optical and thermal CVD diamond processed at The Plasma Laboratory, Hebei Institute of Laser in China.  Natural diamond has always been of extreme scientific interest due to its unmatched properties including hardness, thermal conductivity, broadband transparency, chemical inertness and high temperature stability.  However, the cost of natural diamond substrates is prohibitive in most cases.  The big news in the last two decades is that CVD processes have been developed to the point where economical artificial diamond substrates are now readily available.

Torr Scientific is offering CVD diamond substrates in various shapes for use in applications such as thermal mounts and laser windows as well as sealed into vacuum viewport assemblies for high vacuum applications.  The CVD diamond performance is very close to that of natural diamond, so our customers can now take advantage of thermal conductivity that is five times that of copper and high transparency for optical wavelengths that range from 225 nanometers to beyond 100 microns! Please contact TSL to request quotations for your specific applications.

Torr Scientific offers a professional coating service for x-ray anodes used on all the major surface analysis instruments. The company can coat both twin and monochromator anodes used on VG, Kratos, VSW, Leybold, Physical Electronic etc. instruments, using the usual materials Mg, Al, plus the more exotic such as Silver, Zirconium, Yttrium, Titanium etc..

All work is conducted to the highest standards in an ISO 9000 approved company by people who have a strong background in surface analysis related instrumentation and therefore understand the issues of cleanliness and contamination. The latest sputter coating technologies are used to produce clean, pure, strongly adhering coatings, which are very rugged.

We offer several different levels of service

• a simple clean and recoat (to specified thickness) with Mg, Al etc.
• a more specialist recoat including a proprietary barrier layer for more recent instruments using higher powered / stressed anodes,
• or simply for older instruments to enhance anode lifetime
• to a full re-tip, cathode replacement and re-build
• Mono or Twin anodes
• Silver or copper tips, plus diamond and longer life tips 

Torr Scientific offers an extensive range of vacuum components to compliment the many UHV viewports. Fittings are supplied in KF, CF & ISO formats in 304L & 316L stainless steel. The range includes flanges, fittings, bellows and hoses. Seal components such as copper gaskets and centering rings are supplied competitively and promptly.
