Ocean Optics DT-MINI-2-GS Deuterium Tungsten Halogen Light Source

Ocean Optics DT-MINI-2-GS Deuterium Tungsten Halogen Light Source with Shutter

The DT-MINI-2-GS Deuterium Tungsten Halogen Light Source also utilizes the bulb with the 0.5-mm diameter aperture. Its added feature is a shutter for blocking the light path, which can be controlled via a manual switch or TTL. There is also a switch for turning the deuterium source on and off, and one for turning the tungsten halogen source on and off; each switch can be used independently of the other.

0.5 mm Aperture: More Powerful Output:

The original DT-MINI was our first foray into a compact and versatile UV-NIR light source, and is still a great choice for a range of applications and measurements. The advantage of the newer DT-MINI-2 and DT-MINI-2-GS is that they use a bulb with a 0.5 mm diameter aperture, which results in more focused, uniform beam coupling to our optical fibers.

Rack-mount Version:

Rack-mount versions of DT-MINI-series lamps are available. These sources can be hard-wired to a spectrometer channel and racked into a Dual Box, Rack Box or Desktop Box with other accessories.

DT-MINI-2 Deuterium Tungsten Halogen Light Source Ordering Information:
DT-MINI-2-GS Miniature combination deuterium and tungsten halogen light source with shutter option and function control switches
DT-MINI-2-B* Spare bulb for DT-MINI-2 and DT-MINI-2-GS


* The DT-MINI-2-B Bulb can only be used in the DT-MINI-2 and DT-MINI-2-GS sources. Likewise, the DT-MINI-B Bulb can only be used in the DT-MINI and DT-MINI-GS.

Note: The overall power output across the combined spectrum is very stable -- with drift about 1.0% per hour. The tungsten source is very stable at <1.0% per hour. As a plasma emitter, the deuterium source is less stable. Changes within the plasma lead to changes in the light coupled in the fiber and drive can vary by wavelength.
