The novel optical filtering technology offered by Photon etc's Tunable Laser Source offers high efficiency and out-of-band rejection and is suited for tunable excitation sources in Raman and fluorescence spectroscopy.
Key Features
The key features of the Tunable Laser Source are:
- High out-of-band rejection
- Free-space or fiber coupled
- Pico- or nanosecond sources
- Pointing and power stability
- Wide tuning range
LLFT Contrast
The LLFT Contrast acts as a filter for the tunable laser source.
Applications
Retinal imaging - Targeting the emergent field of retinal imaging, Optina Diagnostics and Photon etc. now offers a new Metabolic Hyperspectral Retinal Camera (MHRC), particularly developed for ophthalmological studies. 
Optina and Photon etc. technology is the only one that gives to health professionals a tool to establish an early diagnosis of age related macular degeneration (AMD). The MHRC allows the non-invasive localization of structures and biomolecules in the retina using their specific spectral signatures.
Spectrally resolved LBIC: The tunable laser source from Photon etc. is ideal to perform spectrally resolved light beam induced (LBIC) cartographies. Those measurements allow researchers to map the minority carrier diffusion length (Ln) and external quantum efficiency (EQE) over the whole solar cell.
