What size is the exit pupil?

I don't know what size the exit pupil is. I do know that for the price you are getting some damn good glass. The quality of these binos are amazing. So don't let the size of the exit pupil keep you from buying these.

Sorry I could not get an accurate measurement of the eye piece. I could measure the male end on the scope. It measured 1.614 inches and there was another that measured 1.364. Hope this helps you.

basically, the same size as the reading lens in a pair of bifocals. you can trim them if necessary

The exit at it's widest point measures 3/8 inch. Remember, this is a flash suppressor and is is common for the width of the exit hole be greater that the barrel diameter in order to not impede the bullet trajectory and speed leaving the barrel. I hope this helps.

What I did was, using a set of metric vernier calipers measure the outside diameter of bothe the Ocular lens (eyepiece) and the objective lens. Then using the Butler creek measurement table, chose the size as close too or slightly smaller than that measurement. I too had issues with finding what I needed and I did have to surf about a bit, but I finally found a table that had all of scope cap sizes and measurements. Hope this helps

The viewing area encompassed by the lens is a complex shape. Left, top, and right sides are convex (frame bows outward) and the bottom side is concave (frame bows inward). Left side lens dimension=2 inches; right side lens dimension=2.25 inches; top side lens dimension=3.9inches; bottom side lens dimension=3.4inches. To use the illumination feature, the device must be held so that its handle is on the right as the LED lights only point downward in that orientation.

Not sure how to answer as I'm inexperienced with scopes so far. But here are some dimensions from the manual:Eye relief: 3.8inobjective tube diameter: 1.67ineyepiece outside diameter: 1.73 inlength: 11.5inMounted with good clearance using medium profile rings on #12 weaver mounts. Not too close to existing folding rear iron sight. I hope that helps.

The physical size is about 4 1/2 from eye piece to end of lens and 4 1/4 from side to side.

If I measured correctly it's 1.5 inches. Like I said I'm still trying to learn how to use it. I haven't had much experience with optics

About six inches. Probably a little less. One of the huge benefits of this wonderful little lens!

Just measure the outside diameter (OD) of the bottom of the eyepiece barrel. Less than 1" it has a 0.965" (24.5 mm) OD; otherwise, it is an 1.25" (31.75 mm) eyepiece.

2 5/8 inches. It works very well so far. I wish I could us it on other tele lenses I own.

The first number is the power of the lens, that is how much it will magnify the image. The second number represents the diameter of the lens in mm. They work together to calculate a number called the "exit pupil" or "exit ratio". Take the lens size and divide it by the power to get this number. The higher the number, the brighter the image. For example, 10x50 will give an exit ratio of 5.0, 8x42 would be 5.25, 10x42 would be 4.2. In my opinion, the exit ratio is more important than the power. My favorite binoculars are 8x50 (6.25) but I also just bought 10x50 as a gift who is delighted with that configuration. Stay away from high-power binoculars. They, for me, are too hard to keep steady due to the high magnification. I hope this helps. -Norm

lens diameter is 1.125", outside diameter of front bezel is 1.25", diameter of main body is 1.0625", length of main body is 3.1875" with (0.5" extension), length of head (front bezel) is 1.375", overall length 4.625", fully zoomed the main body is extended by .375". The extension is used for the rechargeable 18650 lithium ion batteries. These measurement were just made with a tape measure, and my eye. So there may be inaccuracies.

The veiwing portal measures 2" x4", plenty of sight capability, good veiwing area, and darkness adjustable for different heat settings. Hope this helps, I personally love this helmet, it works great for me.

It is 4.5 inches long when collapsed and6.5 inches when extended. The lense end is 2inches diameter and the handle end is almost 1.5 inches diameter.
