Phocus Essential

Based on the Ring-Cavity optical parametric oscilaltor (OPO) technology, the Phocus ESSENTIAL represents the ideal light source for photoacoustic imaging applications that require high pulse energies and NIR wavelengths for deep penetration of biological tissue. High damage thresholds combined with minimal maintenance and turn-key operation reduce system down-time and allow ease of operation. The system provides an ultra-compact, light-sealed, transportable cart designed for deployment into pre-clinical environments. A customizable, safety-interlocked fiber bundle delivers light from the system to the instrumentation and prevents system operation without fiber attachement. Motorized harmonics and fiber bundle delivery provide a completely, hands-free system tunable laser system.

Option 1 Group

Energy Level

The Phocus can be configured for two energy levels, as presented in the tuning graphs. Select the desired configuration based on the graph. The outside dimensions are identical.

Option 2 Group

Fast Tuning

This option enables fast switching of the output wavelength such that each consecutive pulse can be set to any wavelength within the wavelength range of the system. The user can enter a sequence of wavelengths into the control software, with any step size (zero to full range) in any order, and the system will generate these wavelengths pulse after pulse. It can be set to stop after a single sequence or to repeat the sequence as defined by the end-user.

Option 4 Group

Real-time Wavelength Monitoring

The Wavemeter provides real time measurement of the OPO wavelength, which is displayed in the control software screen. The option allows closed-loop tuning of the OPO , which provides better than 1 nm accuracy of the Signal wavelength.
