Torr Scientific relocated to a modern 410 m2 factory in Bexhill-on-Sea, East Sussex in August 2009. A 270 m2 first floor extension was completed in October 2011 increasing floor space at the Sussex manufacturing site to 690 m2.

In response to demand from customers requiring contamination free products for UHV applications, the company invested in a new 110 m2 cleanroom to provide a laboratory manufacturing facility in which thin-film coatings and hermetic seals are processed, and UHV and Optical instrumentation is assembled, inspected and packed.

TSL took delivery of a new vacuum furnace in August 2010. The furnace, supplied by Specnow Ltd., has a hot zone four times larger than previous furnaces at TSL. The system incorporates Specnow’s latest Microlink control system with data management and logging. The extra capacity will meet growing demand for TSL fused silica and sapphire UHV viewports and allow further development of ceramic to metal seals.

A new turntable and TIG welding equipment has been set up at Torr Scientific. All viewports are now welded within the company allowing full quality control over the complete viewport manufacturing process. Weld rings in kovar, stainless steel and non-magnetic tantalum are welded in to 304L and 316LN flanges.

All brazed and welded components are leak tested using TSL’s Inficon mass spectrometer helium leak tester.

Cleaning and assembly of UHV instrumentation takes place in laminar flow cabinets in cleanroom conditions.

The e-beam vacuum coating system is used predominantly to process anti-reflective coatings. TSL upgraded the electronic control units on the e-beam system in 2009 in partnership with Ferrotec, specialists in electron beam evaporator equipment. The upgrade has improved efficiency and reliability of the anti-reflecting coating process. Viewports are coated to customer specified wavelengths of application.
