2 W Xenon Flash Lamp Module
L13651/L13821 Series
Light source ideal for portable compact analytical
instrument
The L13651 and L13821 series are 2 W xenon flash lamp modules integrated
with a regulated drive power supply and a lamp trigger circuit. These lamp
modules have the same performance as the conventional 2 W lamp modules
but operate on either 12 V or 5 V.
Features
High output
High stability: 0.4 % CV (typ.)
Preadjusted light-emitting point (L13651)
Cylindrically stacked board type (L13821)
Applications
Spectroscopic analysis
Water quality and pollution analysis (TOC/TN, TP, etc.)
Air pollution analysis (NOx, SOx, etc.)
Blood analysis

*1 Guaranteed life is defined as the time when the light output at 190 nm to 1100 nm in 2 W
operation falls below 50 % of the initial value or light output stability exceeds 2.0 % CV.
