LASER FILTERING OPTICAL SYSTEM

摘要

An optical loupe (12) includes a housing (30), an eyepiece lens (66) supported in the housing (30), and an objective lens (44) supported in the housing (30). The optical loupe (12) further includes a filter lens (80) supported in the housing (30) and adapted to prevent the transmission of electromagnetic radiation of at least a predetermined wavelength. In another embodiment, a user-wearable optical system includes a user-wearable device (10) and an optical loupe (12) having an objective lens (44), an eyepiece lens (66), and a filter lens ((80)) supported in a housing (30). The filter lens (80) is adapted to prevent the transmission of electromagnetic radiation of at least a predetermined wavelength.
