High Intensity Deuterium Halogen Source
Despite its compact size the DH-mini produces strong output across the UV-Visible and
near-IR from 200-2500 nm. The DH-mini enables applications that are otherwise
challenging for compact light sources, such as fiber probe-based reflection measure-
ments where throughput is a challenge. Absorption and transmission measurements
with opaque or optically dense samples also benefit from the high intensity of the
DH-mini.
Ultimate Ease of Use
The DH-mini is packed with features that make it easy to use. The tungsten and deuteri-
um 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.
A Small Broadband Source, Ideal for Integration
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 15 pin TTL connector. Galvanic isolation of the TTL pulse
provides reliable performance in complicated environments like an electrically noisy
production floor.
