StellarNet, Inc. BLUE-Wave Fiber Optic Spectrometer NIR2

The newly released StellarNet BLUE-Wave Spectrometers are fiber optic coupled instruments with a wide selection of models for  measurements in 190-1150nm wavelength ranges. Each unit contains a USB interface with a snap shot memory to provide instantaneous spectral image from the highly sensitive CCD with options for 2048 or 3648 elements. Various models provide a choice of grating range and slit resolutions. New and improved electronics with a high speed 16-bit digitizer allows for fast data acquisition and a signal to noise of 1000:1! Up to 8 units can be daisy chained together and are able to run simultaneously. Additionally the new BLUE-Wave spectrometers can be powered directly from your PC USB-2 port.  A single strand fiber optic cable or probe assembly delivers input via standard SMA 905 fiber optic connector with a choice of cable lengths. The spectrograph optics are exceptionally robust in a vibration tolerant modular design, with no moving parts.The detachable spectrograph assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable, process, and lab applications. Several units may be daisy-chained using a standard USB hub allowing simple configurations for dual and multi-beam applications in chemistry, spectroradiometry, and PORTA-LIBS.
Additional BLUE-Wave measurement applications include emission wavelength monitoring /characterization of tunable lasers or LED’s and other sources such as elemental emissions from plasma & Laser Induced Breakdown Spectroscopy. Also Bragg grating technology enables optical sensing of many parameters including temperature and pressure. Thin film thickness measurements can be made using sample specular reflectance. The small size and weight makes the BLUE-Wave spectrometers just perfect for portable and OEM applications. CCD has best sensitivity and PDA has best SNR.

The StellarNet GREEN-Wave low cost Spectrometers are fiber optic coupled instruments with a wide selection of models for measurements in 190-1150nm wavelength ranges.

The spectrograph optics are exceptionally robust in a vibration tolerant modular design, with no moving parts.

StellarNets’ high performance InGaAs spectrometers cover the NIR wavelength range from 0.9-2.3 μm.  The units are exceptionally robust with no moving parts and are packaged in small rugged metal enclosures (2.75� x 4� x 6�) for portable, process, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25μm by 500μm tall to provide maximum sensitivity. The detector has an integrated thermo electric cooler (TEC) maintained at –10 °C, stabilized within +/-0.1 °C.  The RED-Wave NIR InGaAs spectrometers use single strand SMA 905 fiber optic input. Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis.
Extended range systems for 1.5-2.2μm are available in 512 or 1024 element InGaAs PDA’s with 25 x 250um tall pixels. Because of reduced sensitivity and higher dark noise, the extended range InGaAs spectrometers are primarily used for measuring tunable lasers, characterizing optics, or chemical absorption & transmission thru cuvettes, flow cells, and dip probes.
