From Lincoln`s Reference: Glare is said to reduce the ability to see,
and hastens fatigue. Glare is wasted since it lowers the effectiveness
of useful light. Glare is high light energy over a measurable period of
time from above normal angles of vision (30 to 90-degrees above the
vertical). I think this means you don`t want a bright light shining in
your eyes. It`s glaring and impairs vision for awhile.

Hi Richard,

Your continued research into the topic that the originator could not
identify reveals the problems of Glare being a subjective response and
not a technical specification.

However, I have already provided technical clues to answer:
"What is the wavelength of Glare?"
that has so far evaded absolutely any response from our binary
engineer.

So far the suggestions have been that it matters to a WHO, and there
is a practical WHY to reveal the WHEREFORE. The differences in
Photopic and Scotopic vision narrow down the wavelength, but there is
a vast gulf between them. Even being a binary choice, there is still
the chance of being wrong that puts the gag on his stepping forward
with an answer. In the end I will be alone in completing this I
suppose. It will cap off my full mathematical treatment and the
exposure of this full cancellation that is TEN TIMES BRIGHTER THAN THE
SUN ;-)

This topic of Glare, being his alone, has subsequently been identified
by him as being inconsequential detail, or better yet, wholly from my
distorted imagination (but only when I examine this point).

There is still much to mine here. With errors so abundant, it is
difficult to choose any one aspect and not have to correct three
aspects of its distortions.

EXACTLY!!! When the glare is exactly the same frequency as the
forward laser beam, and when refraction has been eliminated,
as it is in a transmission line, your postings become completely
irrelevant, but I am not surprised since you seem to be protecting
some cow you consider to be sacred.

That's OK, I will bide my time and reveal this TOO, later.

The solution to this week's puzzler:
2(bad) you can('t) solve this.

Since, in my example, glare has been completely
eliminated, you are asking: "What is the wavelength
of nothing?" My guess is that it would be the same
as the wavelength of the sound of one hand clapping.

In my example, if we increase the thickness of the thin
film to 1/2WL, it will maximize the glare to 2% of the
incident laser power. In that case, the glare would be
the same wavelength as the single-frequency coherent
laser. In the mental example, the wavelength doesn't
matter so 632.8 nm might be a logical popular choice.
I have a collimated laser of that wavelength.

WRONG

This isn't even within the range of the two wavelength clues offered.



Dear Readers,

Let's examine why this answer is so wholly lacking:

1. The wavelength described, as already noted, is a wild foul out of
the ballpark;

2. a popular choice? This conjecture is broadly announced with the
characteristic couching of terms "might be" to hedge the answer. My
later discussion will reveal why no one would choose this at all;

3. logical choice? Absolutely no logic is offered - hence it is
exactly what it appears to be - a wild guess, My later discussion
will point out why this has no basis in logic whatever;

4. the wavelength doesn't matter? Given this is application driven,
the topic of Glare being just that, Glare is highly specific to
wavelength and is very intimately associated with perception. These
are two areas of discussion that exhibit considerable errors.

Naturally I will tie this all together in later discussion in a new
thread. And I will show:
"What is the wavelength of Glare?"
the answer of which has already been posted by me (see above) ;-)

Glare occurs entirely internally to the eye, and there are two main types of
glare effects. The first is the corona, which forms the fuzzy glow you see
around a light at night, or the rays which seem to shoot out from the light
of the sun. The second is the lenticular halo, which is only seen when the
pupils are dilated enough and is a color banded halo which is usually
visible surrounding the corona.

Hi Fred,

Yes, this is another reason why using physiological characteristics to
explain otherwise dry, technical issues is so fraught with error.
That error is because not everyone perceives the "problem" (being
"Glare" here) in the same way. Further, within the population of
readers here, cataracts and "Glare" are a very common issue that is
wholly unrelated to the treatment of thin film interference and
"Glare."

I have spent a number of years in designing optical system to reduce
what is called "Glare" in this technical sense. In other words, the
suffering component was an artificial eye, so to speak, a
Photomultiplier Tube (PMT) within a fluorescence detection system that
achieved accuracies in the hundredths of percent. The abysmal math
performed in relation to this topic is amateurish in the extreme,
especially considering that so little more work was needed to offer
vastly better results.

It has been quite obvious that this poor math was necessary to support
a faulty premise: complete cancellation. There is no such thing,
especially within the context of "Glare."

Is that what I am missing? Richard Clark has cataracts?

Actually, I got that wavelength from _Optics_, by Hecht.
Hecht says: "The He-Ne laser is still among the most popular
devices of it kind, ... (632.8 nm)." So your argument is with
Hecht, not with me. Good luck on that one.

Luck is unnecessary when the quote is so obviously disassociated from
the context of Glare or its wavelength. Such a struggle you put on,
like an old wife wriggling into a girdle. Such exhibitionism would be
pornographic if it weren't so comic. :-)
