 HARDcam is a very high cadence, high sensitivity solar imager which is installed as a common-user instrument on the Dunn Solar Telescope at the National Solar Observatory in New Mexico, USA. Initially commissioned on the telescope in July 2011, HARDcam has since provided data for high-impact publications appearing in a wealth of international peer-reviewed journals. HARDcam has the ability to be used alongside existing [[rosa | ROSA]] cameras as it can make use of the external synchronisation triggers synonymous with the [[rosa | ROSA]] instrument. Therefore, HARDcam can provide simultaneous high-resolution chromospheric observations to complement [[rosa | ROSA]] data sequences, with a typical frame rate over an order-of-magnitude higher than that provided by an existing [[rosa | ROSA]] camera. It employs an EMCCD which has been tuned to provide optimum sensitivity (95% QE) in the red portion of the electromagnetic spectrum, and typically observes under the following conditions: ​ HARDcam is a very high cadence, high sensitivity solar imager which is installed as a common-user instrument on the Dunn Solar Telescope at the National Solar Observatory in New Mexico, USA.
