Key Features
• Quantitative Determination of Photosensitizer Concentration in vivo
• High Sensitivity to All Popular Photosensitizers
• Diagnostics with Autofluorescent Measurements
• PDT Control Option
• Powerful Software
• Light Guide Fiber Optic Probe

Spectroscopy system LESA-01 allows in vivo locally determination of photosensitizer accumulating level in any patient's organs and tissues accessible for fiber optic probe. System is used during photodynamic therapy of intracavity, interstitial and superficial tumors.

Optical properties of the system are optimal for using during photodynamic therapy with different photosensitizers for measurements of biological tissues autofluorescence.

User-friendly powerful software for Windows enables to compare accumulating of photosensitizer in affected and intact tissue. Useful facilities for tissue monitoring and drug accumulation analysis are provided.

Spectroscopy system consists of He-Ne laser source LHN633-25 for photosensitizer excitation and miniature general-purpose spectrometer LESA-01GP for registration and analysis of fluorescent signal.

System may be built in embedded PC with touch screen and protected keyboard according to DIN41494 standard for 19" rack mounting.
