HF204HT


32 mm High Speed Shutters

The HF204HT 32 mm high-speed shutter attaches to the Prior HF108 filter wheel or can be used as a standalone unit controlled by the ProScan control system. It has a shutter speed of 10 ms and a maximum operation frequency of 40 Hz, in bursts of 4 seconds or less, with an interval of 60 seconds between each burst. For constant operation, the maximum frequency is 10 Hz. A large selection of adapters allows it to fit most commonly used microscopes and it can be mounted on either the illumination or emission side. The HF202HT is available for use with 25 mm filters.
