Instruction:
In recent years the combination
of array detector and spectrograph has become the system of choice for
spectroscopy. Spectral Products' SM line of computer-based miniature array
spectrometers offer state-of-the-art performance yet have compact form factors.
Their versatile design and ease of use make them the first choice for scientific
and industrial applications. SM series optical benches are designed to provide
stable operation over a wide range of ambient temperatures.
SM product lines
together with their accessories (light
sources, filters,
optical fibers
and sampling
accessories) are now used throughout
the world in such systems as Raman spectroscopy, emission and excitation
fluorescence/luminescence spectroscopy, arc/spark/plasma spectroscopy,
spectrophotometry, spectroradiometry, laser breakdown spectroscopy,
picosecond laser analysis, ratiometry, infrared measurements, color/LED
measurement, process control/diagnostic/calibration and so on.
Spectral
Products provides a wide
selection of UV/VIS/NIR(CCD-Si, NMOS PDA) and NIR/MIR (InGaAs, PbS and PbSe) detectors,
and some useful sampling
accessories for their application.
Technology:
SP's SM miniature spectrometers are packed with great features and performance
in a small footprint. The SM series spectrometers are based on a crossed Czerny-Turner
configuration.
 
Operation:
Connections between the spectrometer
and the computer interface are made via a shielded electrical cable. Detector
arrays are also included in the same housing in hand held versions. SM spectrometers
can be interfaced to computers via USB, PCI, PCMCIA, ISA, etc. Especially, our
USB 2.0, 16-bit A/D interface can give our SM series spectrometers
some of best effective dynamic ranges and high data acquisition speed available.
Considerations:
- Detector:
SM CCD spectrometers employ 2048 pixels Si-CCD (Sony ILX511),
new 3648 pixels Si-CCD (Toshiba
TCD1304), 512-2048 pixels NMOS PDA (Hamamatsu series), 512 pixels multiplexed InGaAs,
PbS, PbSe detector arrays with high sensitivity. A
sensing element height of 200nm to 1,050nm (CCD)/0.9μm to 1.7μm (InGaAs)/ 1.0μm to 3.0μm (PbS)/1.5μm to 5.0μm (PbSe) maximizes the detector
light collection capability. For UV and near IR regions where silicon detector
response is inherently weak, we provide a variety of sensitivity enhancement
coatings for detector arrays. Every
IR range detector is thermoelectrically cooled and temperature stabilized to ensure
long-term operation stability
- Optics:
Our
pioneering optics and coating technologies also allow us to take another step
further to reduce energy lost between optical surfaces. In addition, a
cylindrical focusing lens in front of the detector array can further enhance the effective pixel size.
- Filters:
By use
of SP's unique variable filters in SM spectrometers, a wide, simultaneous
wavelength coverage is achieved, free of higher order interference.
- Gratings
and Slits:
We offer various ruled and holographic gratings depending
on the wavelength range. Also, several slits are available for various
resolution and throughput.
- Application:
SM spectrometers can be applied to various fields such as:
- Semiconductor industry process dignostics
- Light source/Sample spectrum analysis
- Color/Flourescence measurement
- Biology/Chemistry/Biochemistry/Medical applications
- Food and Agriculture/Pollution measurement
- Chemicals/Plastics/Polymers analysis
- Petrochemicals/Pharmaceutical analysis
Our continuous product development effort is
adding to the versatility of our spectrometer line everyday.
