Ocean Optics DH-mini Deuterium Halogen Light Source for the UV-Vis-NIR
This light source is being phased out, please contact us for current options
Despite its compact size the DH-mini produces strong output across the UV-Visible and near-IR from 200-2500 nm. Absor
ption and transmission measurements with opaque or optically dense samples benefit from the high intensity of the DH-mini.
The DH-mini is packed with features that make it easy to use. The tungsten and deuterium source bulbs can be turned on and off individually, limiting stray light in challenging measurements. An internal shutter can be opened and closed using simple buttons with LED indicators on the front panel. For automated processes or remote measurements, a TTL signal also can be used to control all functions.
The DH-mini has been designed with OEM integration in mind. Not only does it provide high power from a small footprint, it also makes integration a breeze with full remote control of all functions via a 4-pin TTL connector. Galvanic isolation of the TTL pulse provides reliable performance in complicated environments like an electrically noisy production floor.
