These instruments are used to measure wavelength
emissions from Lasers, Laser Diodes and LED's into
the near infrared. A fiber optic cable is used to couple
the output from the test device into the spectrometer. The
instrument allows characterization of the wavelength stability with
time, temperature, and device drive current.
Depending on your application and wavelength
requirements, StellarNet can offer high resolution spectrometers up to
0.1nm resolution. Contact StellarNet for availability of
other wavelength range and resolutions.
Optional Configurations
Multi-channel systems for continuous monitoring of
several devices are easily configured by daisy chaining additional
units.
Optical Fibers
For 1310 and 1550nm laser diodes, a fiber is used to couple the ST device connector with an XNIR2
spectrometer input connector (SMA). Other couplings use a 400um fiber
with a lens attached to a SMA bulkhead fitting that can be easily
mounted in the device emission path.
FreeSpectraWizSoftware
The powerful
SpectraWiz® 32 bit spectrometer software is provided
free of charge with every
spectrometer instrument. This includes
drivers and customizable software
for operation on Win95 / Win98
/ WinNT / WinME /
Win2000 /WinXP. The SpectraWiz software is
considered the "Swiss Army Knife of Spectroscopy and may be used to
accurately measure wavelength emissions, reflectance, transmission,
absorption, concentrations, and absolute intensities. In addition
to real-time spectroscopy, SpectraWiz® has built-in applications
for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab
concentration analyzer, and UV level monitors.

Experimental Setup for
Laser, Laser Diode, and LED characterization
using EPP2000-HR spectrometer with an IC2 integrating sphere and/or
cosine receptor.
StellarNet Cosine Receptors-
Allow collection of collect
light with an 180° field of view using demountable diffusers with ~10%
loss.
The
CR1-UVN
is a ˝” diameter
near
cosine receptor using sanded fused silica
diffuser for 200-1700nm. Has reduced 90° FOV and low 7% loss
See more of
StellarNet's cosine receptor information!!
SpectraWiz software
enables
wavelength measurements of emission peaks, peak area centroid, FWHM
(Full Width Half Max), and dBm.
Power and
InterFace
The instruments are
constructed in a small metal enclosure of 6x3.5x1.5 inches, with a fiber
optic SMA connection on the front panel.
Portable spectrometers have an easy to use plug and
play interface with USB-2 connection and +5VDC power adapter for
120VAC-60HZ. These power adapters are small wall mount transformers with
U.S. style 2 prong plugs. For usage outside the U.S.A., we offer an
upgrade to universal power adapters. If you don't have a USB-2 port,
connecting the spectrometer to a second EPP printer port on your
computer is most convenient and recommended. For portable notebook
computers that don't have a USB-2 port or an EPP capable printer port,
we offer the PCMCIA card style EPP interface.
