Armasight PVS-14 6x Lens

Beautifully made product, a quality product. Threads on PVS-14 lenses of different manufacture, stays screwed in when adjusting focus. Focus operation remains unchanged. Amazing magnification increase with any standard PVS-14, greatly increasing functionality of the PVS-14. It does suck light though, and there is noticeable vignetting around the edges. Long range observation was aided by my Armasight's IR-XLR 940 IR illuminator with their own doubler attached. This lens doubler screws into the IR light and focuses the beam into a tight round circle that has much greater range, but at the sacrifice of peripheral light. It's simply a 2x magnifier for your IR light.In urban areas with ambient this 6x lens works great, although image is best in the center, and the whole extreme outside of the image is dark, where vignetting completely took over. This is true with or without additional illumination of the IR940. The image is excellent with some ambient light. The lens does not distort the image in the center, but rather offers greater detail than without the additional magnification. I found it too front heavy and a bit comical to wear it on a helmet mounted PVS-14 but if someone finds a reason for this, have fun.Beautiful lens, optically excellent, offers great capabilities increase when used with enough light. Comes with rubber ocular and objective covers and drawstring pouch.
