Recent advances in CMOS technology have opened the way for numerous applications in science and industry which bring a number of technical advances in performance and benefits to existing imaging areas.
Pop Bio has pioneered the use of this new technology to significantly improve the existing CCD camera technology in the capture and imaging of gels and blots.
The Advantages of CMOS Sensors
The CMOS sensor has outstanding imaging qualities in the visible spectrum, is low cost, small and easy to control. This makes the CMOS sensor perfect for the consumer market where costs are particularly important. However these same qualities are now being harnessed in the scientific field where the ubiquitous CCD camera has for so long held sway.
In the scientific field more manufacturers are finding the CMOS sensor can give higher levels of quality and are considerably easier to handle than traditional CCD cameras. The higher resolutions offered by the CMOS sensor and their faster data flow speed have multiplied in recent years such that faster more efficient processors are needed.
The key features of the CMOS sensor – price, resolution, speed, low noise – are all paramount in many scientific applications and especially so in the field of gel and blot imaging. Pixel size has also increased to the point where they can be as large if not bigger than CCD’s.
Using line-scanning it is now possible to use these sensors in low-light, high performance applications such as chemiluminescent Western Blot image capture. Clever use of how the line scanner can be controlled to capture low level light and to monitor light level output has revolutionised this technique.
