FIELD: medical equipment. ^ SUBSTANCE: medical device equipped with artificial light source and optical filter contains the case, incandescent lamp footing support bearing light source, and the fan. The case wall contains the mirror mounted on the axial handle. The optical filter is provided in the objective lens outside of the specified case through the hole in its wall. Besides the case includes slot adjuster mounted in front of the shutter disk with elliptic slots. Herewith the slots are arranged on the shutter disk coaxially to the axis of the optical filter. While the adjuster is being rotated in front of the shutter disk in service, adjustable slots of specified shape and size are formed thus modulating frequency and amplitude of the light when light wave passing through. ^ EFFECT: higher penetration of light flux into the tissue. ^ 4 cl, 3 dwg |
