Mechanical design ensures durability in harsh environmental conditions, as well as high accuracy and stability in varying operational situations, utilizing the following components:
- High-precision, high-grade mechanical components
- High accuracy and stability ground and hard-coated parts
- Advanced materials to ensure athermalization and low-SWaP design
- Durability to harsh environmental conditions
Ophir optimizes lens assemblies for weight and rigidity to withstand shock and vibration. Engineers design and test moving parts for long life without maintenance in extreme environmental conditions. Lens assemblies meet or exceed IP67 environmental standard.
With cutting-edge, in-house capabilities for optical component production, components can be made in many shapes and materials, suited to their specific application. Moreover, large optics with high precision are crucial for obtaining small fields of view (FOV) and our advanced high-end lens production capabilities is one of the key contributors to addressing the challenges.
Optical coatings are also vital for optical performance. Ophir uses high durability (HD) and low reflection hard carbon (LRHC) AR coatings to maximize both performance and toughness for operability in extreme environmental conditions. These coatings are suitable for multispectral applications as well.
Ophir offers a broad range of products for security and surveillance applications with the following key characteristics, meeting the application’s demands:
- Maintaining boresight through the full zoom range
- Maintaining fixed F# through the full zoom range
- Maintaining focus through the full zoom range
- Operating in low temperatures and harsh environmental conditions
- Maintaining high image quality
- Providing fast FOV change with continuous optical zoom position adjustability
- Providing compatibility with major MWIR & LWIR detectors
To demonstrate our capabilities, we present the following three long EFL zoom lenses that provide state-of-the-art capabilities for long-range security & surveillance applications:
