Vision Research unveils global 4K high-speed camera

Feb. 10, 2017

Wayne, NJ. Vision Research, a manufacturer of digital high-speed imaging systems, today introduced the Phantom Flex4K-GS, a high-speed camera with a 35-mm, 9.4-megapixel sensor and global shutter. Designed for demanding applications in the scientific research as well as defense and aerospace industries, it builds upon the technology of Vision Research’s Phantom digital cinema products.

The Flex4K-GS, developed on top of the established Flex4K platform, employs a custom sensor capable of recording 1,000 frames per second (fps) at 4K resolution, while its global shutter ensures that every pixel is exposed to light at the same moment in time. This capability is important in aerospace applications, as it prevents motion artifacts with propellers, motors, and other rotating objects and ensures timing precision throughout the entirety of each frame. Also critical to defense is the camera’s build quality. Its isolated electronics and thermal design allow for operation in environments within the temperature range of -20°C to +50°C, all the while maintaining a stable image.

“There have always been trade-offs between speed, sensitivity, and resolution in modern CMOS-based cameras, but Vision Research is changing the game with the new Flex4K-GS,” said product manager Toni Lucatorto. “The camera brings pixel resolution to the forefront, allowing for incredibly fine detail and improved visibility of phenomena and measurements.”

The Flex4K-GS is available with either 64 GB or 128 GB of RAM and works with CineMag IV nonvolatile memory magazines for the fastest data transfer. One of its unique features is the ability to save either uncompressed raw or compressed video in the Apple ProRes 422 HQ video format. When working with ProRes, a 2TB CineMag-IV will hold several hours’ worth of footage. The Flex4K-GS is also fully compatible with Phantom PCC software and can be synchronized and used in combination with other Phantom camera models.

Key Specifications of the Phantom Flex4K-GS include a global shutter switchable to rolling shutter for increased dynamic range; frame rates of 938 fps at 4,096 x 2,304, 1,000 fps at 4,096 x 2,160, and 1,975 fps at 2,048 x 1,080; a 5-μs minimum exposure; an internal mechanical shutter for black references; 3G-SDI video outputs; and dual-SDI mode for simultaneous live video and playback.
