Resolve Optics (Chesham, Bucks, UK) has developed a variant of its Model 207 miniature motorised zoom lens, enabling a manufacturer of remotely operated vehicles (ROV’s) to help improve the deep sea welding capability of their system.

The Model 207 Motorized Miniature Zoom Lens from Resolve Optics Ltd. can focus on an object at infinity right down to an object positioned just 35 millimetres in front of the lens. This unique close focus feature allowed the lens to be placed closer to the welding head and incorporation of an ND spot to provide a wide aperture range of f/2.8 - f /160 enables the operator to monitor the weld as it happens without the camera flaring out. Designed for use with miniature CCTV cameras - the Model 207 (50 × 34 × 31 mm) is the smallest stand-alone zoom lens commercially available.
