Singular Photonics Raises €1.85 Million to Advance Next-Generation SPAD Image Sensors

Aug 19, 2026 | By Oliver Bennett

Singular Photonics, a semiconductor company based in Edinburgh, has raised €1.85 million (US$2.15 million) in a funding round. The round was oversubscribed, meaning the company received more investor interest than the amount it planned to raise.

SUMMARY

Singular Photonics has raised €1.85 million (US$2.15 million) in an oversubscribed funding round.
The round was led by ACF Investors, with several other investors participating.
The new funding will help the company expand its sensor portfolio and develop new features.

The funding round was led by ACF Investors. Other investors included Wren Capital, Cambridge Angels, Scottish Enterprise, Quantum Exponential and Old College Capital.

Singular Photonics develops SPAD image sensors, which can detect individual particles of light and process data directly on the chip. The company also announced that Dipesh Patel, former CTO of semiconductor company Arm, has joined its board of directors.

“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. This oversubscribed round means we can respond faster – expanding our sensor portfolio and bringing new features to market on our customers’ timelines, not just our own,” said CEO Shahida Imani.

“Singular Photonics is an exciting addition to our portfolio, combining world-leading sensor science with genuine commercial promise. The industry is moving from capturing images to generating actionable insights directly from light itself, and Singular has both the technology and the team to lead that shift. We’re delighted to back them into their next phase of growth,” said Tim Mills, Managing Partner at ACF Investors.

Singular Photonics was founded in February 2024 by CEO Imani, CTO Dr. Aravind Venugopalan, Professor Robert Henderson, and Dr. Neil Finlayson. The company was created as a spin-out from Professor Henderson's research lab at the University of Edinburgh.

The company came out of stealth mode in January 2025. Singular Photonics is a fabless semiconductor company, meaning it designs its chips and sensors but does not manufacture them itself.

Singular Photonics develops SPAD image sensors with computing built directly into the chip. The company says traditional image sensors are reaching their limits in how much information they can capture. SPAD technology uses single-photon detection, which could allow sensors to capture more detailed information and enable new types of imaging applications.
