The new TrueChrome Metrics camera from Stemmer Imaging provides fully integrated digital image capture and measurement for micro and macro scientific imaging applications, with the need for a PC. By plugging a mouse into the camera and connecting the HDMI camera output to a monitor, a wide range of multiform measurement tools allows measurements to be made on the high-quality images produced. The camera is capable of delivering measurements with a resolution of 10 nanometres, and the images are generated by the 2.3 megapixel Sony Exmor CMOS sensor. This allows the user to manipulate live images without any monitor lag.
Self-contained measurement camera
An image compare mode also permits side-by-side comparison of live and previously stored images. Automatic optimisation of camera settings optimises image quality whatever the application. Exposure time, saturation and automatic white balance produce high-quality images with minimal need for manual adjustment, whether for brightfield imaging or darkfield birefringent crystal imaging. Full manual control is available should it be needed.
The powerful inbuilt measurement functionality includes freehand lines, rectangles, polygons, circles and angles. In addition, with the ability to measure point-line distance, angles, the length of curves and lines, the camera can measure the perimeter and area of enclosed features such as: rectangles, polygons, and circles. Results can be exported as Excel or text files to the SD card. The camera is easily calibrated and up to 10 calibration files can be saved for different microscope or lens configurations.
The embedded user interface is easy to use. There are only two icons on screen, one for image capture and the other for the settings menu. The measurement menu appears simply by right clicking anywhere on the live image. For users who prefer integrated PC control instead of standalone operation, the camera can also be connected and controlled directly to a computer via a USB2.0 cable.
