Abstract
A device for maintaining an optical path of an optical imaging system free of fog includes an elongated member having a distal end and a proximal end, a near-infrared (NIR) light-absorbing optical window disposed at the distal end, and an optical system disposed along the optical path. The device also includes a coupling module coupled to the elongated member at the proximal end and configured to transmit near-infrared light to the NIR light-absorbing optical window along the optical path and receive a light beam from an area of interest along the optical path.
