Hawkeye® Blue Fixed Prism Borescopes offer directions-of-view of 0°, 30°, 70°, and 90°. They have medium to wide fields-of-view, ranging from 55° to 100°.
Use a Hawkeye Blue Fixed Prism Borescope for particularly large, dark spaces. Illumination and imaging channels are independent on Hawkeye Blue Rigid Borescopes, increasing image, clarity and contrast.
In comparison, when borescopes with mirror tubes are used to inspect large, dark areas, the illuminating light and the image can intermix, lowering clarity and contrast if the mirror is not clean.
