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.

Purge Device: All night vision devices require nitrogen purging after assembly to keep them from internally fogging during temperature changes. We also recommend sending the unit in annually to maintain the purge of the 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, it will result in actual headaches to occur with the end user 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.
