The Standard of Accuracy

The grating-based HighFinesse/ Ångstrom’ spectrometers offer the capability for a very accurate simultaneous measurement of both wavelength and linewidth of laser sources. With a resolving power up to 40000 and a measurement speed up to 500 MHz, the product series covers the range from 192 nm to 11000 nm, allowing measurements of both pulsed and cw lasers. The grating based technology enables the analysis of laser sources over a large linewidth range. Connected to the PC via USB, after a simple software installation the spectrometers are ready for use.

The MISS (Mini Imaging Spatial Spectrometer) is an innovative imaging spectrometer for ultrashort pulse characterization. It provides optical spectra with spatial resolution in one direction of a laser beam, thus allowing for vertical and horizontal spatial chirp measurements. Both free-space and fiber input versions are available.

LightMachinery's spectrometers are setting the new standard for range, resolution, cost and size. The HyperFine HF series spectrometer is designed for LIBS or simultaneous Brillouin and Raman spectroscopy. With 1 pm resolution in a small package size it offers an affordable approach to advanced spectroscopic applications. The Hyperfine HN Series spectrometer is a smaller version with about 25-pm resolution anywhere in the UV, visible and NIR wavelength ranges. The Hyperfine HN is ideal for characterizing light sources such as laser spectra in real time.

Creating a Spectrum of Optical Solutions

We can design and manufacture custom spectrometers incorporating original or replicated gratings. Industry leading hyperspectral-imaging systems utilize our own designed and produced components and assemblies, so you can be assured of the very highest quality.

Change the Color of Light to Expand your Possibilities!

GWU's portfolio of CCD-based spectrometers provides a great variety of features to fulfill nearly any requirement of versatile applications. The detection range covers the UV to near-infrared spectrum and even reaches out to the mid-infrared at 2.6 µm. Models with tiny footprint, e.g. for wavelength monitoring in OEM applications, as well as thermo-electric (TE) cooled devices with high resolution, high sensitivity and ultra-low noise for weak-light applications, such as fluorescence sensing or Raman analysis, are offered.

Thorlabs spectrometer development and manufacturing capabilities cover a wide range of wavelengths and applications. The compact crossed Czerny–Turner spectrometers are fiber compatible and available for three different wavelength ranges. For applications that require higher spectral resolution, our optical spectrum analyzers employ a Michelson interferometric design compatible with fiber-coupled and free-space light sources that can be used in spectrometer or even wavelength meter mode. They are complemented by Fabry–Pérot interferometers that allow users to examine the fine spectral characteristics of e.g., CW lasers. In contrast, our holographic grating spectrometer is designed for integration into OCT systems and provides high measurement speed. For our unique Raman spectrograph, we use a coded aperture technology with exceptionally large étendue.

CNI offers fiber-optic spectrometers, multi-channel spectrometers and some spectroscopy systems like a LIBS system, Raman spectrum systems and others which are widely used in spectroscopy applications.

The Future Depends on Optics

Edmund Optics offers a wide variety of spectrometers, including spectrometers that have been optimized for Raman or fluorescence spectroscopy. Raman spectrometers are ideal for Raman applications in the visible to the near infrared. The fluorescence spectrometers are ideal for use in low light fluorescence applications where the ability to detect weak signals is crucial for proper measurement. Additionally, fluorescence spectrometers feature broadband spectral response ranges for detecting wide wavelength bands along with a wide slit width for increased throughput.

Femtoseconds with Confidence

The HARPIA spectroscopy systems perform a variety of sophisticated time-resolved measurements in a compact footprint. The HARPIA-TA is a transient absorption spectroscopy system extendable with time-resolved fluorescence, microscopy, and other modules. The HARPIA-TG is a novel transient grating system for carrier diffusion and lifetime measurements. For a single-supplier solution, the HARPIA systems are combined with a PHAROS or a CARBIDE laser together with ORPHEUS series or I-OPA series of OPAs.

NLIR's BUNDLE Spectrometer offers fast and accurate spectral measurements in the MIR/MWIR range of 2.0 – 5.0 µm. When combined with high-end VIS/NIR spectrometers, it provides enhanced capabilities with readout rates of either 1.4 kHz or 130 kHz, a minimum detection power of 5 pW/nm, and a resolution of 6 cm⁻¹.

NLIR's CUSTOM Spectrometer can be tailored to meet specific requirements for spectral measurements in the mid-infrared wavelength range.

Hamamatsu Photonics offers a range of spectrometers and spectrum sensors, including mini-spectrometers, FTIR engines, MEMS-FPI spectrum sensors, and Raman spectroscopic modules.

The waveScan spectrometer by APE is a compact and cost-efficient optical spectrometer for characterizing light sources, e.g. ultrafast as well as cw laser systems. The waveScan device family cover the spectral range from 200 nm to 6300 nm and allows also the characterization of low-repetition rate lasers down to 100 Hz. The rotating grating technology achieves high resolution measurements at a 5 Hz spectral measurement rates. This makes waveScan an ideal real-time alignment tool for laser systems.

YOUR KEY to innovation and success

EVEREST, by UltraFast Innovations (UFI®), is a soft X-ray/XUV/VUV spectrograph that features aberration-corrected flat-field imaging and is available with three gratings covering the spectral ranges 1–17 nm (1240–73 eV), 5–80 nm (248–15.5 eV) and 24–200 nm (51.7–6.2 eV). In order to maximize light collection, the spectrometer can be used without an entrance slit over a variety of source distances, with 3–17 nm, 10–80 nm and 24–200 nm spectral coverage. Its modular design is able to match different experimental geometries and configurations. It features an integrated slit holder, gate valve, and filter insertion unit, as well as a 3-axis motorized grating positioning.
