June 15th 2020,Changchun, China -Gpixel announces the further expansion of the popular GSENSE product family with the GSENSE1516BSI, a large format BSI CMOS image sensor for high-end scientific applications. The sensor is designed around Gpixel’s high performance 15 µm square rolling shutter pixel, provides 4096 x 4096 resolution (16.7 MP), and supports up to 9fps in dual gain HDR mode.
Like other sensors in the GSENSE family, the GSENSE1516BSI can read out a single exposure with two different gain settings, providing two separate images that when recombined achieve up to 90dB intra-scene dynamic range. Using the low gain channel, the sensor’s full well capacity is 134ke–, maximizing signal to noise in the bright parts of the image. Through the high gain channel, the sensor achieves a read noise of 4e–, perfect for the measurement of faint signals.
The generous 15 µm pixel size combined with 95% peak quantum efficiency provides excellent sensitivity for the most demanding low light scientific applications. The 61mm x 61mm photoactive area increases the imaging field of view, and in combination with the sensor’s high frame rate, maximizes the data throughput for applications like speckle imaging in astronomy.
Engineering samples of the GSENSE1516BSI will be available for evaluation in July 2020. For more information, please contact Gpixel at info@gpixel.com.
