Ray1 and Ray1 EX SWIR cameras

The Ray1 and Ray1 EX SWIR cameras from Ray Imaging Solutions Ltd. are compact, high‑performance imaging solutions designed to deliver reliable short‑wave infrared (SWIR) data in demanding environments. Built around advanced colloidal quantum dot sensor technology, these cameras combine wide spectral sensitivity, integrated thermal management, and flexible software support into a robust, ready‑to‑deploy platform. Whether used in industrial inspection, scientific research, or machine vision systems, the Ray1 family offers a powerful balance between performance, usability, and form factor.

Both models are engineered for seamless integration. With integrated cooling, standardized mounts, and common development interfaces, the Ray1 and Ray1 EX reduce the time and effort required to move from evaluation to deployment. The standard Ray1 covers the core SWIR band up to 1,700 nm, while the Ray1 EX extends sensitivity to 2,200 nm, enabling imaging capabilities well beyond visible and near‑infrared systems.

Key features

Quantum dot SWIR sensor technology

The Ray1 series utilizes colloidal quantum dot sensor technology to deliver high sensitivity across the SWIR spectrum. This approach provides excellent performance at a competitive size and cost, making advanced infrared imaging accessible for a wide range of applications.

Two spectral configurations for different needs

The Ray1 offers sensitivity from 900 nm to 1,700 nm, ideal for standard SWIR inspection and imaging tasks. The Ray1 EX extends the wavelength range to 2,200 nm, enabling detection of additional material properties and phenomena that are invisible at shorter wavelengths.

High‑quality VGA imaging

Both cameras feature a VGA resolution of 640 × 512 pixels with a 15 µm square pixel size and a sensor area of 9.68 × 7.68 mm. With over 99.9 % operating pixels and a dynamic range of 65 dB, they provide clean, detailed images suitable for quantitative analysis.

Integrated lens and flexible optics

The Ray1 includes an integrated 25 mm lens with an adjustable f‑number from f/1.4 to f/22, delivering flexibility in depth of field and light control. A C‑mount interface and support for multiple lens options allow system designers to tailor the field of view and working distance, from close‑range inspection at 0.3 m to infinity.

Thermoelectric cooling for stable performance

An integrated thermoelectric cooler (TEC) minimizes dark noise and stabilizes sensor performance across varying temperatures. This is especially important for long measurement sessions and low‑light SWIR applications where image consistency is critical.

Compact, rugged design

With camera dimensions of just 68 × 70 × 60 mm, the Ray1 family fits easily into space‑constrained systems. The aluminum housing provides durability and efficient heat dissipation. The Ray1 configuration weighs approximately 665 g with lens, while the Ray1 EX weighs around 520 g.

Efficient power and data interfaces

Both models operate from a 12 V DC supply and consume approximately 5.5 W with TEC enabled. Data transfer is handled through USB 3.0 Micro‑B, supporting frame rates of up to 20 fps for responsive imaging and analysis.

Cross‑platform software support

Ray Imaging Solutions provides an SDK supporting C++, C#, and Python, ensuring easy integration into existing software environments. The cameras are compatible with Windows, Ubuntu, and NVIDIA Jetson platforms, making them suitable for both desktop and embedded systems.

Applications

Industrial inspection and process control, Semiconductor and electronics analysis, Scientific research and laboratory imaging, Security, surveillance, and environmental sensing
