Low pass filter attachments for use with dental curing lights

摘要

A dental curing light system is configured to include a dental curing light (100) having a device body (102) with a proximal handle portion (106) and a distal head portion (104). One or more light sources (120) for generating light are disposed on or within the device body (102). Generated light is emitted from the distal head portion (104) and includes wavelengths greater than about 420 nm and wavelengths less than 420 nm. A separate head attachment member or device (160) is coupleable over the distal head (110) of the device body (102) so as to receive substantially all light emitted from the distal head portion (104) of the device body (102).

主权项

1. A dental curing light system, comprising:
a dental curing light device comprising:
a device body having a proximal handle portion and a distal head portion from which light is emitted during use; andone or more light sources disposed on or within the device body and that are configured for generating light that includes wavelengths of light greater than about 420 nm and wavelengths of light less than about 420 nm; and a head attachment member coupleable to the distal head portion of the device body and configured so as to receive substantially all light emitted from the distal head portion of the device body, the head attachment member comprising a low pass filter configured to filter out wavelengths of light greater than a specified wavelength and transmit substantially all wavelengths of light less than the specified wavelength, wherein the specified wavelength is about 420 nm or less such that and substantially no wavelengths of light greater than the specified wavelength of about 420 nm or less are transmitted through the low pass filter and substantially all wavelengths of light less than the specified wavelength of about 420 nm or less are transmitted through the low pass filter.
