Hi,
this looks like a coated lens, so no polishing! Otherwise you get a "cloudy" surface....
You can only try to find the same lens with a scratched front lens, and then change the element.
Have done that with a Inon UFL-165AD with the rear element.
Regards,
Wolfgang

Hi,

Sorry to see that.
Is this the UWL-H100 67MM. type 1?

The scratch is really close to the edge of the lens. If you manage to align the scratch with the top center or lower center position of the lens into the housing most probably you can get the scratch out of the field of view of the sensor and if so it does not mess with the pictures

Thanks for the input I will give that a try I was trying to find it on some photos but will try again once I'm home from my dive trip

You might be able to get the scratch out of field of view (see scheme)

To do what the previous poster says check that you dont see it in the fov

if you do undo the plastic LD part with an allen key and rotate one or two positions then reset

Have you actually even seen the scratch in the image? My guess is you'll never notice it. See the following for an extreme example.

Repairs can be quite pricey. I probably wouldn't bother unless it really stands out in your images, if it's noticeable  at all.

Thank I haven't noticed it as mentioned earlier I dont think it is in front of the sensor. Thanks for the info!
