SpectroFluorometer System consisting of High Sensitivity SILVER-Nova TE Cooled Spectrometer, CUV-F, and the SL1-LED excitation source
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. 
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. Interchangeable slit upgrade available for SILVER-Nova!
HYPER-Nova UVIS high performance spectrometers use a Low Dark Current (LDC) technology to provide lower background noise than is possible with traditional font/back-illuminated detectors. HYPER-Nova’s CCD detector is vacuum sealed and cooled to -60 °C with peak quantum efficiencies up to 95%
Miniature fiber optic light source with replaceable LEDs and nose cone. LED-Kit includes a set of 6 LEDs: LED-390, LED-470, LED-502, LED-590, LED-660, LED-white. UV LED options available for excitation at 295, 345 and 365nm.
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.
