The evolution of military optronics

Optronics form an integral part of modern operational military equipment. They play a decisive role in the tactical superiority and safety of armed forces. From night vision technology and thermal imaging systems to enhanced head-up displays (HUDs) and augmented reality glasses, such optoelectronic systems are indispensable tools for military operations.

The use of highly sophisticated optronics in extreme environments and the high sensitivity of such systems present manufacturers with special challenges. In particular, the interfaces and connections of the optronics are a potential weak point that is considered crucial for the quality and reliability of the imaging.

Connectivity challenges for optronics:

• Break resistance: The connection systems have to withstand enormous tensile and torsional forces, which can lead to bent or broken contacts if they are not stable enough, thus impairing the functionality of the optronics.
• Environmental compatibility requirements: Military applications are increasingly becoming subject to environmental requirements. The connection systems should therefore comply with the RoHS guidelines so as not to pose a risk to the user or the environment.
• Protection against environmental influences: For a solution that can be used as flexibly as possible, the interfaces and connections of the optronics must be able to withstand extreme environmental conditions such as dust, water and shock. The goal here is to achieve the highest possible IP rating for protection against damage and failure.
• Reliability with the smallest footprint: The connection solutions to be used must also lock securely in confined spaces without placing a long-term strain on the optronics. Conventional push-pull mechanisms increase the leverage effect on the connection due to their design and can therefore impair stability, especially in situations with vibration and shocks.

To meet the requirements of such highly innovative optronics, ODU has developed connection solutions that exceed standards in performance, reliability and robustness.

The ODU-AMC connection solutions with 5-finger coding are many times more robust than conventional half-shell coded systems. They offer reliable protection against twisting and breakage, and also enable the transmission of various data protocols for imaging applications such as HDMI, DisplayPort or coax.

ODU connectors are not only characterised by their break resistance and stability but also meet the highest environmental standards. With an immersion depth of up to 20 meters and protection classes IP6K8 and IP6K9K, they offer reliable protection against water, dust and other environmental influences. This makes them ideally suited for use in harsh environments without reducing the performance of the optronics.

ODU as an experienced provider of interconnectivity

In addition, ODU offers comprehensive support for manufacturers of vision systems and associated accessories, including battery pack manufacturers. The solutions enable improved cross-platform functionality and are equipped with a STANAG 4695 solution for connection to portable battery systems (PDUs) for soldiers.

ODU has many years of experience and is a proven supplier for major OCCAR procurement projects in the field of night vision equipment for the German and Belgian armed forces. ODU is also the main supplier for one of the largest projects for the integration of augmented reality in the US armed forces.

Specialised solutions for hermetically sealed applications

To improve the service life and reliability of the optronics, they are often filled with inert gas such as nitrogen or argon to eliminate an oxygen-containing atmosphere. This prevents the systems from misting up and protects the internal electronics and components from corrosion. Through decades of collaboration with customers, ODU offers extensive experience in the development of customised connection solutions.
