Adjustable field mask aperture enabling ultra-fast imaging with iXon EMCCD Adjustable field mask aperture Adjustable field mask aperture enabling ultra-fast imaging with iXon EMCCD OptoMask is a C-mount to C-mount relay device with precise aperture control which inserts easily between the microscope output and the camera. OptoMask is used in combination with the Crop Mode software feature on iXon EMCCD cameras, resulting in significant increases in Region of Interest (ROI) frame rates. In order to enable Crop Mode it is necessary to accurately optically mask the area of the sensor outside the ROI. Using the OptoMask, a sub-array can be readily defined through positioning of the masking blades, and a cropped area subsequently matched to this in software. Optically Centred Crop Mode with OptoMask The Andor iXon Ultra and iXon Life series come with ‘Optically Centred Crop Mode’, which gives the user the Above: iXon EMCCD Camera with OptoMask mounted to an upright microscope. option to break away from the corner tethered requirement of standard Crop Mode and select a number of pre-defined ROIs that are located in the centre of the image field. Optically centring of the ROI makes this mode extremely appealing to a number of microscopy techniques, including ‘pointillism’ live cell super-resolution microscopy. Above: Optically centered R
