Case Study - Cobalt Light Systems

Cobalt - 750x350


Insight From Light

Cobalt Light Systems develops innovative instruments and technologies for non-invasive, rapid analysis of materials. This technology has applications in airport security to screen liquid contents; pharmaceutical materials analysis of capsules, tablets, gels or solutions; and handheld detection devices to analyse hazardous materials, explosives and narcotics.

Founded in 2008, Cobalt is a spinout from Rainbow partner STFC. The company is based in Milton Park, UK.

Keeping Airports Safer

Heathrow, Gatwick, Charles de Gaulle, Hong Kong International: across Europe and Asia’s busiest and most prestigious airports, Cobalt’s Insight systems are installed into security checkpoint operations to rapidly screen liquids for explosives and other potential threat materials. Cobalt’s best-in-class detection performance also carries the lowest false alarm rate of any ECAC-approved scanner, all without opening the bottle.

What’s In There?

Cobalt’s spatially offset Raman spectroscopy (SORS) technology is a revolutionary tool for verifying raw materials through unopened containers, including multi-layered paper, plastic sacks and opaque bottles and coloured glass, without exposing staff to dangerous chemicals and risking contamination. Cobalt’s rapid transmission Raman spectroscopy (TRS) technology is also used in Pharma; both sensitive and fast, TRS technology can analyse a full tray of 100-200 pharmaceutical tablets or capsules within minutes. Much faster than conventional wet-chemistry methods, customers can release product faster and reduce working capital.

From The Lab To The Market: Investing In Innovation

When the Rainbow Seed Fund team met Professor Pavel Matousek, now Cobalt’s Chief Scientific Officer, at Rainbow partner lab Science and Technology Facilities Council (STFC) in 2005, they could see that his fundamental research known as Spatially Offset Raman Spectroscopy was a genuinely innovative way of analysing materials.

While the technology was compelling, there was not a management team with market experience in place, nor was it clear which industry applications should be the first addressed. Rainbow provided the capital for Cobalt’s initial proof-of-concept experiments on pharmaceutical tablets two years before the company was formed – impossible for nearly all other venture capital funds. Further investment on the back of those tests, alongside later investors, led to the TRS100 product, which went on to be the mainstay of the business for its first five years.

With Rainbow’s additional background expertise in photonics, the Fund helped with early instrumentation development and procurement.

Rainbow then supported Cobalt and the other investors in the recruitment of an experienced management team and spurred Cobalt to raise additional capital to pursue the airport security market.

With a solid management team and a staff of nearly 50, Cobalt continues to advance in the airport security market, as well as in its original business application of rapid identification of materials for pharmaceutical research and manufacturing. Cobalt achieved a 5-fold growth in revenue between 2013 and 2014.

Industry Recognition

Cobalt award

Cobalt’s technology has garnered both The 2014 Royal Academy of Engineering MacRobert Award, the UK’s most prestigious prize for innovation in engineering, and the

Queen’s Award for Enterprise in International Trade 2015. Cobalt was placed top of the 2015 Sunday Times SME Export Track 100 ranking of UK companies with fastest-growing exports, as well as being listed within the top ten on the 2014 Tech Track 100, which ranks the UK’s fastest-growing technology companies.
