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 will be available in 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.
StellarNet fluorescence systems are rugged and shock-proof with no moving parts and are suitable for field applications, factory and industrial conditions; even perfect for a standard laboratory benchtop!
Fluorescence 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!
Fluorescence Accessories StellarNet Systems also include high efficiency fluorescence accessories for a variety of samples including solids, liquids, powders, films and surfaces.
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 qpod 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
SpectroFluorometer Sample Spectra
Powder Lanthanide complex luminescence using BLACK-Comet spectrometer and R600-8-UVVIS-SR fluorescence probe with 7 optical fibers bundled around 1 600μm fiber. For fluorescence measurements the 7 exterior fibers are illuminated by a high output excitation source such as our SL1-LED and the interior fiber collects light emission and returns the signal to the spectrometer. Inline filters can be added to the system to remove excitation frequency artifacts.
