Maintenance and on-site application of electro-optical systems
Field-proven maintenance solutions for electro-optics
Maintaining advanced electro-optical systems in operational conditions is a critical task for defense and security forces worldwide. Whether it’s in a controlled laboratory, a field workshop, or a deployed mission zone, ensuring that equipment such as gun sights, thermal and night vision clip-ons, goggles, and small infrared cameras remain operational is essential to mission success.
To meet these high standards, HGH has developed compact, robust, and user-friendly solutions: OPAL and OPALIN maintenance benches. These systems are designed specifically for on-site and workshop-level diagnostics, calibration, and testing of light electro-optical equipment.
Fast deployment and portability
Time is often critical when it comes to equipment maintenance. That’s why OPAL and OPALIN are built to be easily transportable, quickly set up, with a rugged structure that withstands transport by road or air. They are ideal for mobile workshops, temporary labs, or on-the-go maintenance operations.
Operators can deploy the system within minutes, ensuring minimal downtime for devices that need checking.
Simplified testing for efficient sorting
The first goal of any maintenance session is to determine whether an electro-optical device is functional or defective. To do this efficiently, testing must be straightforward and accessible to all maintenance personnel, not just highly trained engineers.
HGH’s maintenance benches are designed with user-friendly interfaces and streamlined procedures that enable quick diagnostics. Thanks to intuitive workflows, any qualified operator can perform essential checks without needing extensive technical expertise.
OPAL & OPALINHigh-performance measurements
While ease of use is essential, performance must never be compromised. OPAL and OPALIN allow for accurate measurement of critical parameters:
- Spatial resolution in visible and infrared
- Detection and recognition range
- Alignment between optical axes
With OPAL, others major tests can be performed:
- Thermal resolution
- Non uniformity correction
- Bad pixel locations
- Spatial resolution on NVDs
- Gain measurement
- Spot defect detection and location
These capabilities ensure that each piece of equipment is not only operational but performing at optimal levels—especially important before deployment on critical missions.
