University of Edinburgh spinout Singular Photonics has closed an oversubscribed $2.15m (£1.6m) funding round led by ACF Investors, with participation from Wren Capital, Cambridge Angels, Scottish Enterprise, Quantum Exponential and Old College Capital.
Singular Photonics is a fabless semiconductor company developing single photon avalanche diode (SPAD) image sensors with on-chip computation, enabling breakthrough capabilities in machine vision, industrial automation, physical AI, scientific discovery and medical imaging.
Unlike conventional image sensors that measure the intensity of light, SPAD sensors can precisely detect and time individual photons, which are the smallest units of light. The startup says this opens the door to a new generation of imaging systems that can capture information that conventional cameras simply cannot see.
The new capital will accelerate development of a new generation of sensors, expanding the company’s product roadmap.
The investment will also be used to scale engineering capacity and speed time-to-market for new image sensors capable of advancing new applications in different markets.
“This has been a phenomenal year for Singular Photonics,” says Shahida Imani, the startup’s CEO. “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.”
