S2D2 FIBER LIGHT SOURCE
(UV Enhanced Type)
L12515
OVERVIEW
The L12515 is a UV-visible fiber light source containing the
world’s smallest* compact deuterium lamp (S2D2 lamp).
Compared to conventional S2D2 lamps, the L12515 gives
a higher S/N ratio by enhancing the light output in the UV
region.
Despite a small and easy-to-carry size, the L12515 deliv-
ers high output, high stability, and low voltage operation,
making it ideal for assembly into compact chemical analy-
sis devices.
* As of September 2013 by our research
* Light guide is sold separately.
