FIELD: dentistry.
SUBSTANCE: device has sterile single use cap made of material with transparency factor of 100% within 400-500 nm range. External edge surface of cap has to be hyperboloid of rotation, and internal surface of cap is flat. Surface of devices used for hardening of stomatological materials is protected against penetration of the material during exploitation without increase in divergence of light beam. Ability of sterilization of tools being in contact with patient is higher.
EFFECT: improved quality of protection.
