Deuterium Lamps, L2D2 Lamps, X2D2 Lamps
OVERVIEW
The L2D2 lamps are deuterium lamps specifically developed for analytical instruments. These L2D2 lamps offer excellent features essential for light sources in analytical instruments such as long service life, high stability and high output.
The X2D2 lamp (brightness of new deuterium lamp) is two times higher than conventional deuterium lamp ( 0.5 mm aperture type). It can realize high resolution and high throughput of the instruments. |

FEATURES
LONG LIFE
4000 hours (L2-4000 series)
2000 hours (L2-2000 series and X2D2 series)
The L2-4000 series lamps assure an operating life of 4000 hours. This is the longest operating life of any deuterium lamp.

HIGH STABILITY
Fluctuation 0.005 % (p-p) Typ.
(Equivalent to 2 x 10-5 A.U.)
Drift +/- 0.3 %/h
By using a ceramic structure, a uniform and optimum temperature distribution, which are the most important factor for stable operation, can be obtained.
Use of a ceramic structure with excellent thermal stability ensures stable lamp operation even in the presence of ambient temperature variations. |
|
SMALL INTENSITY VARIATIONS
Ceramic electrodes ensure a fixed distance between each electrode. This precise spacing minimizes variation in output light intensity from one lamp to another.
Since the ceramic structure has a small thermal expansion coefficient, there is virtually no movement of the arc emission point during operation.

SELECTION GUIDE
 |
The see-through type electrode structure enables straight-line arrangement of the halogen lamp, deuterium lamp, optical system and optical passage. This simplifies optical design of UV-VIS spectrophotometer etc., and eliminates loss of light amount caused by the half mirror. |
