Resolve Optics Ltd, a leading designer and supplier of specialist lens for demanding applications, was selected by Sekai Electronics (La Mirada, CA, USA) to be the supplier of a unique miniature zoom lens - a key component in their RSC Series Head-Up Display (HUD) camera.

Looking to build a HUD camera that would fit into any aircraft, Sekai Electronics required a zoom lens that combined compactness with flexibility and high performance. The commercial zoom lens that offered the required remote control, variable focus and ruggedness were typically too large and once built into a HUD camera would obscure the pilots view. Modifying its type 207 miniature zoom lens, the smallest zoom lens for 3-chip cameras in the world, Resolve Optics enabled Sekai Electronics to build a 'one size fits all' high resolution colour head-up display camera.

The ruggised zoom lens designed and built for the Sekai RSC Series HUD camera has variable field-of-view delivering optimised focusing on objects from infinity right down to an object placed just 35mm from the lens. The motorised iris facility in the zoom lens is ideal for the wide light level changes encountered in the air and captures the HUD symbology without the interference seen with CCD iris. The zoom lens was also modified to withstand the high levels of vibration, shock and electromagnetic interference static typically found in aircraft.

Resolve Optics Ltd. is a highly knowledgeable, dynamic company focused upon innovative design, and manufacture of production quantities of lenses and optical products on time to strict quality and target price guidelines.

Since 1982, Sekai Electronics has provided video related products and systems to the military, aerospace and space applications worldwide. From submarines to the space shuttle, Sekai products can be found in sea, land, air and space vehicles and applications, and including video cameras, recorders, displays and time code equipment. The RSC Series Head-Up Display camera is currently in operation on more than 10 different aircraft types.
