S2D2 module
L10671D, L10671P, L10671H
The S2D2 compact deuterium lamp is a UV point light source with a drastically reduced size compared to ordinary deuterium lamps. Despite a compact body, the S2D2 lamp has the same high stability as conventional deuterium lamps and a unique electrode structure that delivers high luminance. This compact size of the S2D2 module makes it easy to install in all types of equipment. The dedicated lamp housing and power supply are designed to extract maximum performance from the S2D2 lamp.
Features
- World smallest (*1) deuterium lamp as point light source
- Easy installation due to compact size
- High stability: Fluctuation 0.005 % p-p (Typ.) (Equivalent 2 × 10-5 A.U.）
- External control
- High-output continuous spectrum in UV region
- Low power consumption
*1: By our research (as of March 2010)
Applications
- Spectrophotometry
- Environmental measurement
- Absorption spectrum measurement
- MTP reader
- Pharmaceutical inspection
- High-performance liquid chromatography (HPLC)
- Biological measurement
- Semiconductor inspection
- Optical component inspection
