STATE OF THE ART INDUSTRY EQUIPMENT

At Steele we hold our manufacturing quality above all else. With industry standard process and procedures combined with industry leading equipment to manufacture and service a wide variety of devices.

Hoffman ANV-126A

The Hoffman ANV-126A test set is critical during the assembly process of all night vision products. These processes include:

• Eyepiece diopter focus: All monocular and binocular devices which utilize AN/PVS-14 type eyepieces require that the diopter focus range be set properly in order for them to be able to achieve the proper diopter focus range of +2 to -6. Units built without this calibration procedure most often will not meet the +2 or -6 requirements and will only achieve a partial or skewed focus range.
• Collimation: All dual tube goggles require that each channel of the bino/goggle be collimated. This can only be achieved using a collimation bridge. If a dual tube goggle is not collimated correctly, the end user may experience headaches during use. This is caused by the slightest of misalignments of each image intensified channel in respect to each other. Collimation must be done utilizing a collimation bridge on the ANV-126 Hoffman test set.
• Infinity Set: The Infinity Set is a crucial procedure in ensuring the night vision system’s alignment to infinity. It verifies that the optical system is properly calibrated for distant focus, allowing the user to view objects at long distances clearly. This step is essential for ensuring that all components of the night vision device, such as lenses and optics, function correctly and are aligned for maximum performance in the field.
• Spot Check: Spot checking ensures that all spots inside the image intensifier including, but not limited to, peppering and dark spots meet the minimum quality requirements set by the manufacturer. During this process, we verify that the tube adheres to the manufacturer’s minimum spot allowance, ensuring that even slight variances, such as those exceeding the limit by just 0.001″, are still within acceptable standards. This ensures that the tube performs at its optimal level, providing the highest possible image quality for the end user.

Quality Control

Steele Industries Inc. maintains a robust quality management system and standard operating procedures, all in compliance with our ISO 9001:2015 certification. This ensures that we consistently meet the highest standards across every device we manufacture, service, or repair.

Proper Tools

At Steele Industries, we use only the specialized tools necessary for the manufacture, service, and repair of night vision systems, including models like the AN/PVS-7B/D, AN/PVS-14, AN/PVS-31, RNVG, DTNVS, and various PVS-14 variants. To ensure the highest level of precision, all of our equipment, including torque wrenches which are regularly calibrated to meet the rigorous ISO standards we uphold. This guarantees that each device is assembled to exact specifications and performs reliably. Additionally, we utilize proper Hoffman plates for devices such as the L3Harris GPNVG, BNVD-1531, PVS-31A, PVS-14, and others, ensuring accurate alignment and collimation for optimal functionality.

FULLY TRAINED SPECIALISTS

All Steele Industries employees involved in manufacturing are fully trained to properly service and maintain a wide range of night vision systems. Our team undergoes in-depth training, supported by written documentation and procedures from Hoffman Engineering, as well as our internal standards. We are also certified to build and repair L3Harris PVS-14s, BNVD-1531, and PVS-31A models.
