Your lens should say what distance it is accross the lens (diameter) or you can measure it.

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

The brass ring is one inch wide, the actual lens is 3/4 inch. Works well, the only negative is IF the door will get rained on, then the lens will get moisture in it.

I believe the measurements are listed in specs in the ad but I measured mine and the lens surface is 2.25 wide by 6.5 inches long.

I measure from lens edge to lens edge as mounted in loupe. It's 3/4 of an inch. Or right around 19.4 mm. Actual useable 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.

If you mean the 'Eye Relief', distance from the exit lense to the eye, it is 19.7mm. If you mean the 'Interpupillary distance adjustment', the distance between the eyes, it is 56 to 72mm.

i have no way to measure currently but it is very thin aluminum, so approx. 50mm(lens) + .032"ish sheet metal = a few hairs+/- wider than 50mm.51mm?

They stick out about 5-6 inches. The lens itself is about 2" in diameter. The threaded part is only perhaps 3/4 an inch, so the metal it's going into should be thin or they will have to be modified. I had to and it was a bit of a nightmare on mine, but sure beats all the old oem ones rubber cracking and falling off. Mine have been on for a year without issue.

Diameter of the lens is about 3-1/2". Lamp is battery operated, turned out to be terrific to have in a power outage.

The lens visor is threaded so a filter can be attached. As far as the size goes, there is a reference to 83mm on the lens but I have no idea what it refers to.

The exact length of the lens is TEN and ONE SIXTEENTH of a inch (w/o the housing) I can't tell you the distance but it shines a very long way you will not be disappointed this is a awesome light. Hope this helps you
