Cam wrote "EDIT: The answer that I was really hoping for would have been "Nothing other than possibly a slightly different tint to the lens and a slightly lower power output is different between the two lenses."

I replied... Cam, it was answered right away, you just don't know what "AR Coating" is.... it stands for Anti Reflective Coating!!

You stated that the optical design of this lens is well-known already. I thought it was aspheric on the output side and slightly convex, but weird convex, on the "flat" side. Is there a standard name for this type of lens? Or is it just a standard design for collimating a point source?

It is an aspheric lens...

But there are many design shapes of aspheric lenses. It is the quality of the glass, and more importantly the shape of the lens. Plus the AR coating...

Here are the lens specs:

Default Re: New Blu-ray Lens: 405-G-2

The beam will be plenty clean with it opened. In fact, the latest AixiZ acrylic lenses already have the back opened...

If you don't open the back, the black will start to melt unless your laser is of low power...
