              CMOS – The Latest Developments and Basler Cameras with CMOS Sensors

              CMOS – The Latest Developments and Basler Cameras with CMOS Sensors
              The trend of CMOS cameras becoming increasingly popular in the market has been going on for a while. Switching technologies from CCD to CMOS, however, seems to approach faster than anticipated for some of you. To make switching as easy and uncomplicated as possible, we have compiled the most important questions and answers.   

              When should I begin switching from CCD to CMOS?

              In general, you could start anytime. Switching quickly will let you benefit from a performance increase in your application and from lower camera costs. Therefore, a fast change makes sense. On the other hand, there’s no immediate rush if you’re using CCD-based cameras. They will be available for many years to come. In any case, it is advisable to calculate precisely which option would be more advantageous. 
              What do I have to consider when switching?

              Relatively little. You shouldn’t have any trouble finding a camera with a suitable CMOS sensor. To make it real easy, choose a CMOS sensor with the same optical format your CCD camera has, and you’ll only have to perform minimal adjustments to  your system design. Things we also kept simple if you stay with your standard interface, e.g. Gigabit Ethernet. Basler offers all new CMOS sensors within the 29 mm x 29 mm housing of its ace models which allows for easy replacement of nearly all existing camera designs. It also brings along improved performance in replacement scenarios of analog FireWire cameras, where space limits are a crucial element.  

              What’s important when integrating the latest CMOS-based cameras?

              Integrating a CMOS camera as a replacement of CCD sensors is simpler than expected, especially when you choose standard compliant hardware and software. As camera manufacturers take care of the entire sensor integration including image quality optimization, all you need to pay attention to when choosing the right CMOS camera is to:

              • Determine the correct resolution of the camera: The required resolution depends on the details you want to make visible in your images.
              • Define the required camera interface: The choice of an interface depends on the required cable length, bandwidth, necessary frame rates and real-time capabilities and PC hardware availability. Our Interface Advisor helps you find the best interface for your application.
              • Choose lens and lighting: Changing the sensor format also involves changing the lens. Our Lens Selector makes finding a new lens easy. Lighting must only be adjusted if the sensitivity of the new sensor is different from the previous one. 
              • Integration effort for software and camera control: Cameras complying with  common standards such as „GenICam“, for example, or interface standards like USB3 Vision or GigE Vision, offer uncomplicated integration.
              Which CMOS successors does Basler's portfolio offer today?

              Basler has anticipated the trend towards CMOS sensor technology in industrial cameras early on and offers a broad product portfolio of CMOS cameras with sensors from various manufacturers. Just recently, it equipped two ace GigE and two ace USB 3.0 models with Sony’s IMX174 CMOS sensor. With a resolution of 2.3 MP and frame rates of 50 fps (GigE) and 155 fps (USB 3.0), respectively, this powerful sensor is a recommended choice for demanding applications in the fields of traffic, microscopy and medicine.  
              Furthermore, several ace models were equipped with CMOS sensors of the PYTHON series from ON Semiconductor. These models reach speeds of up to 750 fps and impress with their outstanding image quality. A comprehensive overview of all CMOS successors for the various Basler CCD cameras is available right here.
