High-throughput VPH transmission spectrograph with deep-cooled CCD for fast, low-light Raman measurements.
Omni-iSpecT is a lens-based Raman spectrograph combining a volume phase holographic (VPH) transmission grating, wavelength-optimized AR-coated optics and a deep-cooled CCD camera. The design targets faster acquisition and higher signal-to-noise ratio for low-light Raman work such as remote detection and rapid Raman mapping, and its low focal-plane distortion supports multichannel measurement with minimal crosstalk. The rugged, compact unit suits field and industrial integration as well as academic research, and an SDK is provided for software development.
Key Features
- F/2.3 aperture collects nearly all light from 0.22 NA fibers
- VPH transmission gratings and AR-coated lenses for high throughput in the VIS or NIR
- Large-format CCD covers up to about 4000 cm⁻¹ Raman shift in the visible version
- Aberration correction over a 30 mm image plane for near-axial multichannel acquisition with minimal crosstalk and Raman shift offset
- Typical resolution 5 cm⁻¹ (532 nm version) and 3 cm⁻¹ (785 nm version) with a 50 µm slit
- All optics pre-aligned and pre-calibrated for out-of-the-box operation; SDK available
- Low-pressure gas detection limits (532 nm system, 60 s exposure): CH₄ 2 ppm, CO₂ 3 ppm, H₂ 5 ppm, N₂ and O₂ 20 ppm
Typical Applications
- Low-pressure gas detection
- Confocal Raman spectroscopy
- Process control
- In-vivo and in-vitro medical diagnostics
- Field and industrial Raman instruments
- Remote detection and fast Raman mapping
