Modular research fluorescence spectrometer for steady-state spectra and lifetimes from picoseconds to seconds.
The OmniFluo900 series is a modular fluorescence spectrometer for research in materials science, physics, chemistry, life sciences and agricultural science. It measures both steady-state spectra and fluorescence lifetimes, and can be configured for spectral coverage from the ultraviolet to the mid-infrared and for lifetimes from hundreds of picoseconds to seconds. Microscope and cryostat options add spatially resolved and temperature-dependent measurements.
Key Features
- Modular platform combining steady-state spectra and lifetime measurement from hundreds of picoseconds to seconds
- Water Raman SNR above 10,000:1 with single-photon counting detection
- Spectral coverage from UV to mid-IR (200–5500 nm) with optional PMT, InGaAs and InSb detectors
- 320 mm image-corrected monochromators with triple grating turrets; optional double monochromators for 1 × 10⁻⁹ stray light
- Spectral correction with factory-measured correction files as a standard procedure
- Large sample chamber with side laser port and options for polarizers, cryostats, integrating sphere and microscope
- Software for excitation, emission, synchronous and 3D scans plus kinetic, lifetime and TRES measurements with lifetime fitting
Typical Applications
- Semiconductor photoluminescence (PL) and PLE measurements
- Phosphor reflectance, absorption and quantum yield
- Upconversion fluorescence
- OLED and display materials
- Carbon nanotubes
- Chlorophyll and carotenoid analysis, biomedical fluorescence diagnostics
