I just use my regular adjustable red light, it only takes a couple of minutes to

get polar aligned..not worth the hassles of a permanent setup.

Hi, all.



I recently bought an essentially new (Feb. 2011) G-11, from a chap moving up to a Mach1. I've been familiarizing myself with the scope and its components, and ran into an issue with the illuminator for the polar alignment scope (the one with the integrated battery).



When I first tried to use the PAS, the illuminator failed to illuminate the reticle. The illuminator was functional-- I could see the LED light up when activated and not threaded into the PAS-- but the light either didn't make it to the reticle or was not sufficiently bright to illuminate it.



After looking at the PAS and illuminator indoors, I determined that the PAS was fine and that the problem was the illuminator.



The illuminator had some slightly translucent, white, rubbery (silicone?) stuff covering the LED. I had assumed this was to attenuate the light from the LED, and it certainly had that effect-- it attenuated the light so much that it wasn't enough to light up the reticle. After clearing the white stuff away, the reticle was illuminated fine.



So it works now, and that's all well and good, but I'm wondering whether the white stuff was supposed to be there in the first place; is my illuminator not as bright as it should be, possibly because the battery has been run down? I'd like to know, both to assuage my curiosity and so I have an idea what to expect from it in the future.



Thanks,



Justin

That will be the adhesive they use to mount the led (and board) into the

tube, saves it falling out when you change the battery, though seems

that the quality control department was on holiday when yours made it

out the factory.

One data point: On mine there was no 'gunk' on top of the LED.

Thank you, Mark and David.
