GLOBAL SHUTTER SENSORS
The CMOS sensors used in the Flare 4MP camera feature pipelined global shutter technology. Pipelining allows the sensor to expose a frame during readout of the previous frame, whereas sensors without this feature must either use very short exposure times or be otherwise unable to achieve fast frame rates. Global electronic shutter exposes each pixel in the frame at the same time, as opposed to rolling shutter designs which sequentially expose rows of pixels. The latter approach leads to motion artifacts as well as uneven frame illumination if any bright flashes occur during the exposure period.
HIGH SPEED DIGITAL VIDEO OUTPUTS
With sensors producing hundreds if not thousands of megabytes of video data per second, systems using the Flare 4MP series cameras need a way of accessing this stream of information. As such, the cameras are available with either Camera Link or CoaXPress outputs, both of which are standardized and well-established. System designers have a wide variety of Camera Link and CoaXPress infrastructure parts to choose from, including PC frame grabber cards, cables, fiber-optic range extenders, and of course uncompressed solid-state video recording systems such as the DVR Express Core 2.
LOW POWER, LOW HEAT, LOW NOISE
The Flare 4MP is designed with premium image quality in mind. One of the factors that impacts image quality the most is noise, which can be introduced in a variety of ways. One major driver of noise is the sensor temperature, To minimize the effect of temperature on the image noise, the Flare 4MP camera is designed with low-power electronics and effective passive cooling. The overall power consumption is under 4W for 4MP models and most generated heat is dissipated convectively to the surrounding air through the all-aluminum chassis which acts as a heat-sink to the internal electronics.
HIGH NEAR-INFRARED SENSITIVITY
The Flare 4MP camera can be ordered with three sensor types - monochrome, color (Bayer) and NIR-enhanced monochrome. This version of the sensor has the same frame rate capabilities as the standard monochrome sensor, but are manufactured with a thicker epitaxial layer to boost NIR sensitivity. Specifically, at 900nm the quantum efficiency (QE) doubles from 8% to 16% over the standard monochrome sensor. QE is limited past 1000nm due to the abilities of silicon-based sensors, but for any applications in the 600-1000nm range these sensors offer good sensitivity in addition to high resolution and high frame rates.

HIGH RESOLUTION AND HIGH FRAME RATE
The Flare™ 4MP series is a part of our family of industrial video cameras designed with an advanced CMV4000 CMOS image sensor. These sensors feature high pixel counts, producing highly detailed images with a 4 megapixel resolution. As well, this sensor features very fast readout, allowing frame rates into the hundreds of frames per second. Adjustable region of interest settings and subsampling features allow lower-resolution output formats at much higher frame rates. This flexibility makes the Flare series effective in applications ranging from high-speed motion analysis to automated optical inspection systems and more.
