Unyielding Reliability
At Ohmaris, we do not just design optics; we engineer survival. OHMARIS develops electro-optical systems against applicable military environmental, electromagnetic and platform requirements. Our engineering and supplier network provides access to specialised optical assembly, precision manufacturing, environmental testing and EMI/EMC verification infrastructure according to programme requirements.
Torture Testing Chamber
Select a stress vector to observe system response. Our architectures are designed to maintain 100% operational capacity even under maximum theoretical load.
Combat-Proven Specifications
Programme-specific verification and qualification activities are planned and conducted against the requirements applicable to each product configuration and integration platform. Systems may be developed with reference to standards including MIL-STD-810H, MIL-STD-461G, MIL-STD-1275E, MIL-STD-704, MIL-DTL-901E and MIL-STD-167-1, depending on programme and platform requirements.

Structural Integrity at the Atomic Level
The physical casing of our systems is not merely a box; it is armor. We utilize Aerospace-Grade Aluminum (AL-7075-T6) and Titanium alloys to achieve an unparalleled strength-to-weight ratio. Precision-machined housings and mechanical components can be produced through qualified specialist manufacturing partners.
- Hard Anodized (Type III) exterior for extreme corrosion and salt-fog resistance.
- Nitrogen-purged hermetic sealing guaranteeing IP68 ingress protection.
- Advanced kinematic mounts to isolate sensitive optics from platform hull deformation.
Athermalization & Cleanroom Assembly
Glass and metal expand and contract differently under thermal stress. At -40°C or +71°C, traditional lenses lose focus. Our proprietary Mechanical Athermalization aligns expansion coefficients, ensuring infinite focus without requiring moving parts or motors.
Optical and sensor assemblies can be produced through specialised cleanroom manufacturing partners selected according to programme requirements.
