About Specac

Who are we?

At Specac we undertake design and manufacture of accessories and sample preparation solutions for Fourier Transform Infrared spectroscopy (FTIR), X-Ray Fluorescence spectroscopy (XRF), and near infrared (NIR) process spectroscopy. Design and manufacture occurs at our purpose-built 33,000 square foot high-tech operation located in London.

We were the very first to market a commercial diamond ATR solution with the Golden Gate, which was launched more than 25 years ago and remains a stalwart of labs around the world. We have extensive experience of different kinds of IR sampling accessories going back decades.

Our reach is global. We have offices in the UK, Singapore, China, and the USA as well as an extensive network of regional dealers across the globe. Our customers are diverse, from academia to policing and from manufacturing to cutting-edge chemical diagnostics.

Our onsite demonstration laboratory, the Newton Lab, gives us the ability to test customer samples on site and provide training for users and distributors.


Specac was founded as Spectroscopic Accessories Ltd in January 1971 by Stan Ranson and Bernard Hawker. Their association went back to 1965, when both had worked for Research & Industrial instruments – a company which made sample handling devices for laboratories – until it was purchased and relocated to Scotland by Beckman Instruments. Ranson and Hawker decided to establish their own company and were soon joined by Harry Merralls and Terry Horsley, whose expertise lay in optical manufacturing. The range of products quickly grew to include infrared accessories, optical components and mounts, HPLC valves, as well as complete instruments for far infrared analysis and interferometry.

Specac has spent much of its history part of a larger group of companies. In December 1984, Specac was acquired by Cambridge Electronic Industries (CEI), becoming part of its Defence and Instrumentation division. It was during this period Specac was first set on the path to becoming the leading FTIR accessory manufacturer. The strategic plan of 1990 provided for this transformation and saw the company relocate in 1994 to new dedicated premises as Graseby Specac.

From 1997 to 2015 Specac was part of Smiths Group, one of the UK's largest companies.

In 2015 Specac was purchased from Smiths Group by members of the executive team in partnership with a venture capital trust company, Foresight Group. Specac now employs around 80 people with offices in the USA and the UK and a network of distributors and dealers worldwide.

In 2018, we won the prestigious Queen’s Award for International Trade for outstanding continuous growth in international sales for six years with export representing 90% of these sales.

The highlight in July 2019 was relocating to a brand-new facility, the Specac Science & Innovation Centre.  We continue to grow by developing new products and moving into new application area’s.
