how big a difference does glass really make?

I think it was like 18-22% less power with the glass as its coated for red or ar.

I think they found that if the lens is coated correctly... it greatly increases the power. But there is a noticeable drop in power if they are coated incorrectly

> +12mw Thermal Output! Compared to acrylic at same current.

Thermal output...yeah. : Last time I checked, thermal output is undesired.Maybe it's someone from here? If it is, shame on you for those devious marketing tricks. ;D

It is always possible that the seller is using either an uncoated or correctly coated lens for BR......

I tried looking at my glass lenses at various angles and can always see it is coated.... I see no sign of that on the photo's in the listing.....

Though if he is using something special I think he would have mentioned it.... :-/

[edit]I have asked him this....."Is the lens coated? and if so is it the standard coating for red lasers or a coating designed for 405nm?

Regards rog8811", I await the answer[/edit]

But still no excuse about the "thermal output" bs :

 

[rog8811]

I have my answer......

Hello sir, The glass lenses are not coated for any specific wavelength

I am not sure what that means, either they are not coated or they are coated for some wavelength or other, you decide

Yea, they're either not coated or standard coated for "white", but I'm gonna go with no coatings at all since I don't really see the point in a collimation lens coated for white. :-/ So is that better than acrylic or what? :-?
