Welcome to the Vortex Nation podcast brought to you by lovers of hunting, shooting, public lands, the Second Amendment and good food. All right, how's it going everybody? We're here. We got Jimmy and Mark on this side of the table and across from us is optical engineer Christian Benson again

So we're gonna talk today about light transmission now I'm really eager to talk about this topic with Christian and

optical engineer because light transmission is a phrase that I get see I see getting

thrown around all over the internet. Everybody talks about light transmission and I'm not always certain. I'm not always certain that when I'm talking about everybody out there who's talking about it. A lot of people might not know exactly what

light transmission actually means. I think they have an idea in their head of something

that they see and they equate that in their head as light transmission. I'm also not even

certain I'll throw this out that I know exactly what light transmission

is and means and everything that goes along with that.

So that's what we brought through optical engineering.

So Christian, I don't actually even know where to start so to speak with light transmission because it's again like I said people throw it out there all the time I think a lot of times what people are trying to get at with light transmission is image brightness and how well an optic can do in low light scenarios particularly you know a lot of

hunters want to know this kind of thing so they'll ask you know I want the one with

the best light transmission I've seen percentages put on light transmission number.

So I've seen where someone will say,

this scope has 90 whatever percent light transmission.

And then it's kind of a race

to see who can find the biggest percentage of light transmission.

I've seen scopes that list lower light transmission percentages actually look better

than scopes it lists higher ones and you know there's there's I've heard it's kind of the

Wild West in terms of that there's no real standard and I don't know why don't you go

and do it all. People are measuring different things to come up with that number.

When an optical engineer hears light transmission, what goes through your head?

You kind of mentioned some scopes having numbers and maybe you compare two percentage numbers and it doesn't really
