StellarNet’s
line of research grade fluorescence systems are designed
for a wide range of applications requiring eXtreme sensitivity.
Choose from our research grade BLACK-Comet with concave
grating optics or our high performance SILVER-Nova with
Thermo Electric Cooling (TEC). Sample types include powders,
liquids, films and surfaces and there are options for cuvette,
probe, and/or flow cell accessories. As always, StellarNet
instrumentation is built modularized, compact, and rugged
for field, process, or lab environments.
The compact
spectrometer is the main component of the system and is
preconfigured with high throughput optics and a larger entrance
slit, low noise circuit design, and an ultra-sensitive detector
array for extreme low-light level detection from 200-1100nm.

BLACK-Comet
concave grating spectrometers have ultra low stray light and
enhanced sensitivity due to their superior grating technology.
As opposed to the industry standard Czerny Turner optical
design used in most miniature spectrometers, which employ
mirrors and a plane grating, the BLACK-Comet’s concave
grating is the sole element in the optical grating design,
thus reducing the amount of surfaces in the light path. Scattered
light is thus drastically reduced to 0.02% at 435 nm and 0.2%
at 200 nm. The BLACK-Comet grating has an f-number of f/2
which provides nearly 4-5 times the system light collecting
ability compared to competing models with f-numbers of f/4
and f/5. Additionally, the aberration corrected grating provides
broadband uniform resolution and excellent spectral shapes.
BLACK-Comet TEC models with advanced cooling options are available
since 2016. |
 |
StellarNet’s
SILVER-Nova wide range spectrometer includes an integrated
thermo electric cooler (TEC) added to the detector array to
maintain -15 °C from ambient and achieve a +/-0.1 °C
temperature stabilization increasing the S/N ratio by 60%
at long exposure times, thus dramatically enhancing the instruments
dynamic range. Also, the SILVER-Nova contains a large detector
lens assembly increasing photon collection ability by 3-4x
with 600 and 1000 micron diameter input fibers. These design
optimizations make the SILVER-Nova TEC spectrometer one of
the premier miniature spectrometers for low light detection. |

Excitation Sources
The SL1-LED
fluorescence excitation source includes a nose cone assembly
with an LED kit consisting of 6 LEDs plus a White LED. LEDs
can be easily exchanged without any wiring changes, just pull
one out and push the next one in. Each LED can be used to
induce fluorescence in many experiments. 470nm LED works best
for Riboflavin (vitamin D). Other wavelengths can be found
more optimal for use with different species chemistry.
The SL3
Deuterium Light Source – emits a deep UV spectral output
over the 190- 450nm range and higher. Add a DCX Lens Option
to increase the deuterium lamp intensity x7 times!

R600-8-UVVIS-SR
is a Fluorescence Probe for UV and visible wavelengths with
7 optical fibers bundled around 1 600µm collection fiber.
For fluorescence measurements the 7 exterior fibers are illuminated
by a high output power light source (SL1-LED, SL3, or other)
and the interior fiber is the read fiber that collects the
low light emission and returns the signal to the spectrometer
The CUV-F
is a fiber optic cuvette holder for SL1-LED excitation with
2 collimating lens for measuring fluorescence. F600Y fiber
included for dual pickup. Note: SL1-LED light source and spectrometer
are also pictured
The MFFC
is a mini fluorescence flow cell that has a fiber optic cable
input to send excitation energy through a fused silica window
into a 2-mm inner-diameter sample compartment. Emitted energy
is collected by a second fiber, oriented at 90°, that
connects to a spectrometer configured for fluorescence.
The StellarSCOPE™
Fluorescence Microscopy Accessory comes equipped with an Olympus
research microscope with 4, 10, & 40x objectives, CMOS
1.3 Mpixel Camera, optical switch, and required SMA couplers
& attachments to couple with a standard StellarNet Fluorometer
System.
The CUV-TEMP
is a temperature controlled cuvette holder for fluorescence
& absorbance measurements from -30 °C to +105 °C.
Price includes sample compartment, two imaging lenses, two
collimating lenses, two mirror plugs, submersible pump, cover
with access cap, tubing, cables and a stir bar.
The QCV-5F
is a package of 5 Quartz fluorescence cuvettes with 1cm path
length
