Edinburgh imaging technology company secures $2.15m to accelerate growth

Edinburgh-based Singular Photonics has closed an oversubscribed $2.15 million funding round to accelerate the development of its next generation of SPAD-based image sensors.

The round was led by ACF Investors, with participation from Wren Capital, Cambridge Angels, Scottish Enterprise, Quantum Exponential and Old College Capital. The investment will help Singular Photonics expand its product roadmap, grow its engineering capacity and bring new image sensors to market more quickly in response to growing customer demand.

The company has already doubled its full-year 2025 sales during 2026 to date, with customer activity spanning machine vision, industrial automation, physical AI, scientific discovery and medical imaging.

Singular Photonics CEO Shahida Imani said:

“This has been a phenomenal year for Singular Photonics. We’ve already doubled our 2025 sales, we’re approaching break-even, and our customers are telling us exactly what they want from future products.”

She added that the oversubscribed round will allow the company to respond more quickly to customer demand, expand its sensor portfolio and bring new features to market.

Tim Mills, Managing Partner at ACF Investors, said:

“Singular Photonics is an exciting addition to our portfolio, combining world-leading sensor science with genuine commercial promise.”

He highlighted the growing shift towards technologies capable of generating actionable insights directly from light and the opportunity for Singular Photonics to play a leading role in that market.

Scottish Enterprise has supported the development of Singular Photonics’ SPAD-based image sensors over several years.

Derek Shaw, Director of Company Funding & Investment at Scottish Enterprise, said:

“The Photonics, Quantum, Sensing and Connectivity and Semi-conductors Sector is a key opportunity area for growth for Scotland.”

He added that companies such as Singular Photonics can play an important role in Scotland’s economy by scaling up, creating high-value jobs and competing internationally.

The company has also appointed former Arm CTO Dipesh Patel to its Board of Directors. Dr Patel spent 25 years at Arm, including serving as CTO with responsibility for its Research and Digital IT functions.

Singular Photonics develops image sensors based on single-photon avalanche diodes, or SPADs, which can detect and precisely time individual photons. Its technology also integrates on-chip computation, allowing information to be analysed at the point where light is detected.

The investment provides another strong example of the commercial growth taking place across Scotland’s critical technologies ecosystem, bringing together strengths in photonics, semiconductors, sensing and advanced imaging.
