Our staff has gained a considerable experience in the field of
biomedical optics and lasers. This experience allows us to carry-out
specific, application and product-oriented design and development projects in the area of light-tissue interaction. We provide
optimization and design of biomedical solid-state lasers, laser and flashlamp-based handpieces for the hair
removal and skin photo rejuvenation, as well as special accessories for the treatment of
spider and varicose veins, acne, vertigo, and tattoo removal. We also have some
background in designing scanners for excimer laser-based eye
keratectomy.

We use FEMLAB finite element software along
with Monte-Carlo simulations to model light propagation in biotissues and evaluate optical and
thermal effects of the biomedical light treatment. To simulate the heating
dynamics of biological tissues with full 3-D thermal field
distribution, we use MATLAB, FlexPDE, FastFLO, and our own original software for solving the
coupled set of heating and light transport equations.

simulated map of light intensity distribution in the human
skin, exposed to Nd:YAG laser radiation. The beam was focused
with a high F-number objective as a part of confocal
microscope system for subsurface imaging of human skin.
|
|
Based on simulation results we optimize the optical design of light
sources and beam-delivery systems for targeting particular tissues with
maximum safety and efficacy.

We provide full consulting support to
customers, involved in manufacturing of biomedical light products based on our design, including specific vendor recommendations and detailed
description of quality control and testing procedures.
