UV-VIS-NIR Fiber-Coupled Lamp for Spectroscopy
The OC-DH-Mini-BAL is a compact UV-VIS light source designed for low-power spectral analysis and portable or handheld devices. It integrates a transmissive deuterium lamp, 0.25W tungsten lamp, built-in shutter, optical path, and SMA905 fiber connector within a single housing. Powered by 12V DC / 600 mA, both lamps and the shutter can be independently controlled via TTL signals.

Lifetime and Cyclic Operation
The OC-DH-Mini-BAL uses a high-frequency electrodeless discharge lamp (EDL) as its deuterium source. Unlike conventional lamps, frequent switching does not reduce its lifetime. It supports on-demand operation and cyclic working modes, with a continuous lifetime exceeding 1000 hours. The fiber coupling design further extends service life up to 3 years, and pulse-to-pulse repeatability is better than 0.1%.

Instant Start and Stable Output
The OC-DH-Mini-BAL is a deuterium light source capable of instant ignition and immediate spectral stability. This makes it ideal for pollution monitoring instruments, where only short spectral measurements (a few seconds) are taken intermittently over long periods. Its exceptional repeatability ensures highly stable and consistent measurement results.
