FL-20 Low Noise CMOS Camera: 20 Megapixels, Capturing High Resolution Images at Once
FL-20BW ultra low noise CMOS camera offers high quality images. The 1-inch image sensor covers the best image quality FOV for C-mount; the sensor resolution is up to 20 megapixels so the optical resolution is not lost even when imaging with 4X and 10x microscope objectives which makes it an ideal microscopy camera.
Advanced Cooling Technology Reduces Dark Current Down to 0.001e-/pixel/s
Based on Tucsen’s professional cooling technology from sCMOS cameras, FL-20BW ultra low noise CMOS camera can achieve a dark current level as low as 0.001e/pixel/s, which significantly reduces the hot pixel noise during long exposure time.
High SNR, Balanced with Exposure Time
Quantum efficiency and noise correspond to signal and noise. Respectively, the higher the ratio, the higher the signal-to-noise ratio. While providing high quantum efficiency of 84%, the FL-20BW ultra low noise CMOS camera strives for excellence in noise control, reducing read noise to 0.6e- and dark current to 0.001e-/s, which makes FL-20BW ultra low noise CMOS camera the best camera for high signal-to-noise ratio balanced with exposure time.
Red circle area: Under short-term exposure, sCMOS has the best signal-to- noise ratio because of its high quantum efficiency and low readout noise.
Blue circle area: At the exposure time around above 1 second. The FL-20BW ultra low noise CMOS camera maintains a better signal-to-noise ratio because of the combined advantages of low readout noise and dark current noise, while the SNR of sCMOS drops rapidly, because of the high dark current noise.
The Core Advantage of the FL-20BW: The Most Comprehensive Performance
In the past decade CCD has gradually withdrawn from the scientific imaging arena. The lower-noise faster-speed sCMOS is the leader in advanced scientific imaging. However sCMOS still does not solve the problem of high dark current noise and high cost. So in applications which require long exposure time and the need for cost-effective scientific imaging, users have to continue to use very old CCD cameras. Now Tucsen has introduced the FL-20BW ultra low noise CMOS camera , which achieves the same level of CCD as the dark current noise and cost performance. At the same time it has the typical characteristics of CMOS: lower readout noise and faster speed. It is a camera with the most comprehensive performance.
Disadvantages of cooled CCD cameras: low speed, high readout noise, and discontinued production. These cameras typically have only 10-20fps, which is unsustainable for high frame rates applications. Its readout noise is usually 5-10 e- so the SNR of low-light imaging is low. Moreover, in the process of image sensor production suspension, there have been no new technologies, nor new products are available.
Disadvantages of sCMOS cameras: high dark current noise, high cost. The dark current noise of the cooled sCMOS camera is only slightly less than 1 electron/second, and the signal-to-noise ratio drops rapidly for long exposure times. At the same time, the price of sCMOS is higher than CCD, so it is difficult to completely replace the application of CCD cameras.
The FL-20BW ultra low noise CMOS camera achieves the same level of CCD camera as dark current noise and price/performance ratio, while offering the typical characteristics of CMOS: lower readout noise and faster speed. It is the most balanced camera with comprehensive performance.
