What Makes Steiner Refocus Lens Night Vision Accessory – – 1 out of 2 models Stand Out?
The Steiner Refocus Lens Night Vision Accessory – – 1 out of 2 models promises to solve a frustrating problem for night vision users: the inability to quickly transition between viewing distant objects and performing tasks at close range. Steiner, a name synonymous with high-quality optics, aims to deliver a simple, effective solution. This accessory has the potential to drastically improve the usability of night vision devices in dynamic environments.
I often found myself fumbling with my PVS-14, constantly adjusting the focus ring when switching from scanning the perimeter to reading a map or manipulating gear. It was slow, cumbersome, and potentially dangerous in tactical scenarios. The promise of a flip-down lens that instantly provides close-range focus was incredibly appealing.
Upon unboxing, the Steiner Refocus Lens felt solid and well-made. The polymer construction seemed durable enough to withstand the rigors of field use, and the clamp mechanism appeared robust. It wasn’t overly heavy, which is crucial when adding anything to a head-mounted night vision device.
Several competing products exist, like DIY solutions using magnifying lenses or modified adapters. However, I chose the Steiner option due to the brand’s reputation for optical clarity and ruggedness. I believed a purpose-built solution from a trusted manufacturer would offer better performance and reliability than a makeshift alternative.
My initial reaction was cautiously optimistic. The design seemed clever, but I was eager to see if the Steiner Refocus Lens would live up to its promise of rapid, clear close-range focus without compromising the overall night vision experience.
Real-World Testing: Putting Steiner Refocus Lens Night Vision Accessory – – 1 out of 2 models to the Test
First Use Experience
I first tested the Steiner Refocus Lens during a night navigation exercise in a wooded area. This involved navigating a course using a map and compass under simulated low-light conditions, requiring frequent transitions between long-distance observation and close-up map reading. The fog rolled in that night making the test even more extreme.
The lens performed well in the damp conditions, with no noticeable fogging or condensation. The ease of use was immediately apparent: flipping the lens down for map reading was quick and intuitive, and flipping it back up for distance viewing was equally seamless. The focus was indeed sharp at the specified 20-24 inch range.
The only minor issue was that the added lens slightly reduced the overall field of view. This wasn’t a deal-breaker, but it was something to be aware of.
Extended Use & Reliability
After several months of regular use, the Steiner Refocus Lens has proven to be a valuable addition to my night vision setup. It has held up well to bumps and scrapes, with no signs of cracking or deformation. The clamp mechanism remains secure, and the lens continues to flip smoothly.
Cleaning is straightforward; a simple wipe with a lens cloth is usually sufficient to remove dust or fingerprints. It outperforms my previous attempts to manage close-range tasks with standard night vision focus adjustments. The speed and convenience it offers are significant advantages.
Breaking Down the Features of Steiner Refocus Lens Night Vision Accessory – – 1 out of 2 models
Specifications
The Steiner Refocus Lens Night Vision Accessory – – 1 out of 2 models comes in two versions: one universal model and one specifically designed for the AN/PVS-21.

- Angular Field of View: 30º – This specification refers to the angle of view that the lens provides, and a smaller FOV is expected as a trade off for the close-range focus ability.
- Focus Range: ~20in to 24in – This is the optimal distance for clear focus when the lens is engaged.
- Universal Model Dimensions: 41mm (1.6in) x 54mm (2.1in) x19mm (0.75in) – These compact dimensions ensure that the lens doesn’t add excessive bulk to the NVG.
- Universal Model Weight: 10.5g (0.4 ounces) – The lightweight design minimizes strain and discomfort during extended use.
- AN/PVS-21 Model Dimensions: 48mm (1.7in) x 45mm (1.7in) x 30mm (1.2in)
- AN/PVS-21 Model Weight: (approximate) 12g (0.5 ounces)
- Mounting: Simple finger clamp – Easy and quick attachment to the objective lens.
These specifications are crucial because they directly impact the lens’s usability and compatibility with different NVG systems. The lightweight design and compact dimensions ensure minimal interference with the user’s mobility and comfort.
