Rayotek’s Downhole Annular Video Imaging Sight Glasses are engineered for indirect illuminated imaging in confined, dark, hostile environments. 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.

Durability: Rayotek Downhole Camera Imaging Sight Windows include an optical quality sapphire shield to increase scratch resistance while adding redundant failure security. This added sapphire shield also increases the lifetime of the window and helps protect costly imaging equipment from catastrophic Sight Window failure. In addition, the housing is made of Duplex Stainless Steel; an exceptionally durable and chemically resistant metal.

Rayotek Annular Downhole camera Sight Windows are field tested and proven to be extremely valuable for borehole (downhole) inspection.
