1-2. Operating Principle
The light or excitation source sends light to the Cuvette holder containing sample. The
light interacts with the sample. The light is collected by the spectrometer and the spectral
information is sent to SEC2000
.
The energy is transmitted through Cuvette holder and is
dispersed via a fixed grating across a linear charge-coupled device (CCD) array detector.
A/D converter transforms the analog data collected from the spectrometer into digital
information. This is passed to the software, providing the user with application-specific
information.
1-3. System Overview
1-3-1. Features
Detector
CCD array detector provides the ability to acquire a full spectrum. In the same time, it
takes a scanning unit to sample a single wavelength. The result is a flexible, low-cost
spectrometer with no moving parts and a compact design with a familiar optical design
- diffraction grating (symmetrical optical bench) – and reconfigures it for an optical
bench small enough to fit into the palm of your hand.
Light Source
We offer a complete line of light sources for visible applications. This modular
approach – components are easily mixed and matched – offers remarkably flexible
applications.
1-3-2. Use
SEC2000
provides quantitative and qualitative analytical techniques for the
absorbance and transmittance of visible light especially useful for chemiluminescence,
electroluminescence and photoluminescence that are measured without light source.
1-3-3. Specifications
A miniature spectrometer, SEC2000 couples a reasonable cost and high-performance
with 2,048-element linear CCD-array detector. Thanks to a modular approach, the
components are easily mixed and matched, which offers remarkably flexible
applications.
