Periscope viewer improves ballistic range camera ease of use

Resolve Optics (Chesham, UK) has supplied a ruggedised F-mount periscope to Specialised Imaging (Tring, UK) designed to provide real-time focusing of any prime lens on their SIR3 high-speed Ballistic Range Camera.

Traditionally, most range camera designs have made do with lens focusing systems not designed for the high shock and vibration environment of the ballistic testing range. Resolve Optics was tasked to design and manufacture a rugged and lockable F-mount periscope focusing system for the SIR3 that incorporated a manual iris adjustment enabling use of any prime lens including modern DSLR lenses that have no manual iris control. A micro switch, activated by the mirror slide, was incorporated into the periscope design to ensure that the camera cannot be used while the mirror is in the focusing position.

Mark Pontin, managing director of Resolve Optics, commented, "The design of the Model 329 periscope looks deceptively simple but is packed with all the features required by the customer".

Resolve Optics has for over 20 years developed OEM quantity specialist lens systems and optical designs for small and large high technology businesses. The company designs and supplies compact, ruggedised optical systems for products that operate in environments subject to shock and vibration including industrial inspection, machine vision, aerospace and ballistic range testing.
