1”-format sensors tend to have slightly larger pixels and seemingly go against the trend of pushing for smaller and smaller pixels. However, this is intentional since the goal of getting “more pixels on the same target area” doesn’t necessarily mean that the image quality is also improving.
The larger pixels of 1”-format sensors often have lower noise and better low-light performance and tend to align better with the boundaries of imaging physics and manufacturing tolerances for CMOS lenses.
If an application requires high resolution and size is not a primary driver, then the 1″ class of sensors are ideal candidates. They offer high resolutions with reasonable pixel pitch and excellent performance. These sensors’ size allows lenses that are still well within the commonly-accepted size range of traditional C/CS format be it actually C/CS mount or board-mount.
Such systems are ideally suited to larger drones, OHV applications, Robotics, CV/Machine vision, as well as Enterprise VR/AV and Teleconferencing applications.

High Dynamic Range (HDR)
HDR (high dynamic range) sensors can capture light intensity variations up to six or more orders of magnitude within the same image frame (~120db). This puts a very demanding requirement on lens performance. Sunex has developed design expertise, process know-how, and nested cleanroom manufacturing facilities to eliminate or minimize optical noise (such as ghosts, flare, starbursts, spurious images) in lenses for high-performance applications.
Sensor Module Capabilities
Depending on the need and expertise of our customers, we provide design and manufacturing services for a complete sensor module. We strive to find the best solution for your needs, from designing the schematic, creating the PCB layout, and sourcing all components to building according to your PCB design and parts consignment. At Sunex, we have the in-house expertise and capabilities for lens and sensor board design, manufacturing, and testing to deliver a fully tested sensor module.
Active Alignment Capabilities
To achieve the highest system performance when pairing a high-quality lens with a high-resolution sensor, we recommend that our customers consider an active alignment process. Applying a fully automated 6-axis active alignment in mass production increases yield, shortens cycle times, improves system performance, and lowers part-to-part variance.
