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.

Device for anti-fog endoscope system

System and method for LED light source. According to an embodiment, the present invention provides a an LED light system for emitting substantially white light. The system includes a first dichroic element, the first dichroic element comprises a first dichroic surface having a first coating, the first coating being adapted to reflect over 95% of a first color and transmit over 95% of a second color, the first dichroic surface having a first side and a second side. The system also includes a second dichroic element, the second dichroic element comprises a second dichroic surface having a second coating, the second coating being adapted to reflect over 95% of a third color and transmit 95% of a fourth color, the second dichroic surface having a third side and a fourth side.
