Allied Vision has expanded its Alvium CSI-2 camera series with the introduction of two new models featuring advanced Sony fourth-generation IMX541 and IMX542 Pregius S sensors, alongside a near-infrared (NIR)-enhanced model based on OnSemi’s AR0522 sensor. These updates enhance high-resolution imaging for applications like microscopy and intelligent transportation systems (ITS).

Key Features of the New Models

The Alvium 1800 C-2040 and Alvium 1800 C-1620 are compact cameras designed to incorporate Sony’s fourth-generation IMX back-illuminated CMOS sensors. These sensors utilize Pregius S global shutter technology, ensuring minimal motion blur even at high frame rates.

  • Alvium 1800 C-2040: This model uses the Sony IMX541 sensor in a square format with a C-mount lens. Its compact design makes it ideal for microscopy applications. With its 20.4 MP resolution, it supports a frame rate of 24 fps (8-bit).

  • Alvium 1800 C-1620: Equipped with the Sony IMX542 sensor, this camera features a wide 16:9 aspect ratio and offers nearly double the resolution compared to its predecessor using the second-generation IMX265 sensor. This makes it particularly suitable for ITS applications requiring high-resolution imagery.

Both sensors feature an enhanced back-illuminated pixel structure that improves light capture efficiency, leading to better quantum efficiency (QE), lower readout noise, and higher spatial resolution—all contributing to superior image quality with a wide dynamic range. The smaller 2.74µm pixel size allows for increased resolutions within the same optical format.

Near-Infrared Capabilities

Allied Vision also released the Alvium 1500 C-501 NIR, an NIR-enhanced camera available in both color and monochrome variants. Utilizing OnSemi’s AR0522 rolling shutter sensor, this model excels in capturing images above the visible spectrum (above approximately 750nm wavelength), making it effective for low-light conditions such as dawn or dusk scenarios.
