Our eyes respond differently than camera sensors. However, for lower magnification, a higher pixel count will capture more detail from your microscope. Therefore, if you go out and purchase that 20 Megapixel camera hoping to maximize clarity, know that the “extra pixels” will have NO EFFECT on the resolution of the image, while negatively impacting speed, capacity and sensitivity. In fact, if you are working at a higher magnification, the optical system is limited to about 3–5 Megapixels that can be transferred to the sensor of a camera. The sensor size also determines which magnification c-mount adapter you should use.Īlthough it seems counter-intuitive, higher magnification objectives actually require fewer pixels. 2/3”-1” sensors are used in most scientific cameras in order to maximize both pixel size and quantity. The larger the sensor, the more pixels it can fit. However, it is important to note that larger physical pixel size means fewer pixels can fit on the sensor, reducing resolution.
They are usually adequate for simpler digital imaging and are a less expensive than CCD.Ħ.45µm or larger generally offers clear images with low noise. CMOS cameras deliver the image at a faster rate due to the parallel processing format. In simple terms, cameras that use CCD have advantages in terms of light sensitivity and noise and are more appropriate for applications that require higher performance. CMOS sensors employ a parallel approach in which the charges are read out simultaneously. The second type of sensor, CMOS, stands for Complementary Metal-Oxide Semiconductor. As soon as the image capture is complete, the data is then read sequentially. Basically, the way CCD works is that a charge builds up in each pixel during image capture. The first type, CCD, stands for Charged Coupled Devices. These acronyms refer to the two types of image sensors that cameras use. As you navigate the digital imaging landscape, its helpful to consider the criteria that will ultimately help you in your camera selection. However, as with all new technology, deciding on the right camera option to suit your needs can often lead to just as many questions as answers. Microscope cameras make it possible to capture, record and share incredible images as increased sensitivity, speed and field of view have driven digital microscopy to new heights.
