The Photron deuterium arc lamp has the following technological advantages:

Stable filament

- Using horizontally installed filaments on two sturdy short wire supports can reduce mechanical vibration. This avoids damage or degradation of the cathode during transportation or handling, which often leads to premature failure of the lamp.

Sputtering shielding

-Special shielding can be used to carefully prevent the deposition of cathode material onto the window and discharge cup during operation. This feature helps to reduce intensity loss during the lifespan of the lamp.

envelope

-The use of ultraviolet transmission borosilicate instead of quartz can reduce costs and avoid long-term deterioration of the window area (solar energy conversion). There is no diffusion loss of deuterium.


lifetime

-Each deuterium arc lamp should maintain 50% of its initial energy and hold at 300 mA DC for 1000 hours.


Note: For pulse systems with short duty cycles, when the peak current exceeds 600 mA, the lifespan will be less than the above value. Provide indicators of time elapsed as requested.



application
UV visible spectroscopy, fluorescence spectrophotometry, UV detector connected to HPLC instrument, colorimetric method, refractometer, and non atomic source used as background correction in atomic absorption spectroscopy.

range
There are multiple configurations to choose from, including different filament voltages, terminal connectors, aperture sizes, and brackets, to accommodate many different instruments.
