摘要：
Borescopes and related methods that are configured to preclude or minimize imaging in hazy and/or smoky conditions. In some embodiments, the borescope may comprise a shaft made up, at least in part, of a material that is electrically non-conductive material and/or thermally non-conductive, and a tip positioned at a distal end of the shaft. The tip may comprise at least one light source, such as an LED or array of LEDS, configured to deliver electromagnetic radiation in which no more than about 20% of the total spectral output is in the infrared spectrum. The electromagnetic radiation delivered from the at least one light source may comprise a spectrum having at least one of a local maximum and a global maximum between about 450 and about 495 nm. The at least one light source may be configured to deliver between about 20 and about 75 lumens of visible light.
