A blue laser system for eye diseases (age related macular degeneration, sub-retinal neo-vascularisation in myopia and presumed ocular histoplasmosis syndrome -POHS) photo-dynamic therapy, based on riboflavin as photosensitive substance, has been developed. A CW diode laser at 445 nm wavelength was coupled through an opto-mechanical system to the viewing path of a bio-microscope. The laser beam power in the irradiated area is adjustable between 1 mW and 40 mW, in a spot of 3-5 mm diameter. The irradiation time can be programmed in the range of 1-19 minutes. Currently, the laser system is under clinic tests.

Spectral system (acronym SPECTECH) is designed to meet the following basics: a) to assure measuring tiny optical single lens in a standard configuration; b) configured for reflected or transmitted beam light; c) configured by user off line to monitor manufacturing or mounting optical components; d) to be flexible to be equipped with more than one spectral detector. Initially, it is equipped with two spectral detectors, but in short time to be able to use more than two. e) configured as process spectrophotometer (continuously) to monitor manufacturing or mounting optical components; f) to be updated or upgraded to meet other necessities. SPECTECH system is a modular one, allowing spectral determinations in a wide range of spectrum (385-1100 nm) and with two detectors UV-VIS (190-1100) and NIR (1000-1700nm) the domain can be wider, covering spectrum from 190 to 1700 nm.
