Silveray

Silveray is a Manchester-based deep-tech company developing Digital X-Ray Film (DXF®): a flexible, reusable, and cost-effective digital detector technology that is set to transform industrial radiography and medical imaging. Originally founded as a University of Surrey spinout in 2018 by Professor Ravi Silva CBE, Director of Surrey's Advanced Technology Institute, the company relocated to Greater Manchester in 2022 to access the region's advanced manufacturing talent and academic partnerships, including close collaboration with X-ray specialists at the University of Manchester.

Silveray's core innovation is a nanoparticle-based semiconductor ink that directly converts X-rays into high-resolution digital images on a flexible electronic backplane. Unlike conventional indirect conversion detectors — which are rigid, bulky, and expensive — Silveray's DXF technology is thin, flexible, and affordable. The film can be wrapped around pipes, fed into tight spaces, and plugged directly into a laptop via USB-C for instant digital image capture, replacing the analogue film and chemical development process still used across industrial sectors including oil and gas, aerospace, and construction.

Silveray has raised £4 million in seed funding led by Northern Gritstone, with backing from ACF Investors, Empirical Ventures, Deeptech Labs, and Hamamatsu Ventures. The company is targeting its first industrial product launch in 2025, with longer-term plans to disrupt medical imaging, including mammography and cancer screening, using the same flexible direct-conversion technology.
