2.375" (NPS) Downhole Camera Annular Sight Glass

Rayotek’s Downhole Annular Video Imaging Sight Glasses are engineered for indirect illuminated imaging in confined, dark, hostile environments such as boreholes and piping. Our compact downhole annular camera Sight Glass is a solid, uni-body borosilicate glass window with an integrated annular glass window to be used with an LED ourter ring. This design allows for well-lit, reduced shadow imaging in boreholes while eliminating light interference and minimizing environmental light backscatter.
