More than twice the sensitivity of a CCD, to meet the needs of professional fluorescence imaging.Tucsen Photonics Co., Ltd. Thermoelectric cooling noise reduction technology to meet more professional color fluorescence imaging needsĪs with the top-level sCMOS camera technology from Tucsen, the FL-20 cooled camera operates at -15 ☌ and can ensure long-term reliable operation, significantly reducing the hot pixels caused by the accumulation of dark current, and obtaining a purer fluorescent background image. 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. It is the most balanced camera with comprehensive performance.įL-20 ultra low noise CMOS camera offers high quality images. The FL-20BW 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. 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 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. Moreover, in the process of image sensor production suspension, there have been no new technologies, nor new products are available.ĭisadvantages of sCMOS cameras: high dark current noise, high cost. Its readout noise is usually 5-10 e- so the SNR of low-light imaging is low.
Cooled CCD cameras typically have only 10-20fps, which is unsustainable for high frame rates applications. It is a camera with the most comprehensive performance.ĭisadvantages of cooled CCD cameras: low speed, high readout noise, and discontinued production. At the same time it has the typical characteristics of CMOS: lower readout noise and faster speed. Now Tucsen has introduced the FL-20BW camera, which achieves the same level of CCD as the dark current noise and cost performance. 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. However sCMOS still does not solve the problem of high dark current noise and high cost. The lower-noise faster-speed sCMOS is the leader in advanced scientific imaging. In the past decade CCD has gradually withdrawn from the scientific imaging arena. The Core Advantage of the FL-20BW: the Most Comprehensive Performance The FL- 20BW 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. 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.īlue circle area: At the exposure time around above 1 second.
While providing high quantum efficiency of 84%, the FL-20BW strives for excellence in noise control, reducing read noise to 0.6e- and dark current to 0.001e-/s, which makes FL-20BW the best camera for High signal-to-noise ratio balanced with exposure time. Respectively, the higher the ratio, the higher the signal-to-noise ratio. Quantum efficiency and noise correspond to signal and noise. 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.Īdvanced Cooling Technology Reduces Dark Current Down to 0.001e-/pixel/sīased on Tucsen’s professional cooling technology from sCMOS cameras, FL-20BW can achieve a dark current level as low as 0.001e/pixel/s, which significantly reduces the hot pixel noise during long exposure time. µROC – Smallest Single-shot AutocorrelatorįL-20BW Monochrome Camera 20 Megapixels, Capturing High Resolution Images at Once.GE-VAC In-Vacuum Scientific CCD VUV, EUV, X-Ray.
