If you have a knife edge (dual sided at 45°, 1/8" thick, and you want as little deformation as possible under a 50 lb. load, what would be the ideal alloy?
Harden steel?
Tungsten?
High carbon steel?
Application: two point guitar tremolo, total tension being around 100 lbs.

Hubble uses long exposure too.
Here is the basic idea:
1. Limit viewing area to a small hole before the image is magnified.
2. This shouldn't effect how the lens works, it would simply lengthen the area between the focal point.
3. Use higher illumination to improve detail of resolution...
So could the pinhole method allow for a dramatically brighter light used to view a specimen?
Also, I found the name for "my" theory that already exists and has been proven "practical":

Take a look at the secondary mirror baffle on the Hubble telescope:

Notice the small hole being the focal point:
Tell me again why having a small aperture like a pin hole would not be helpful at all? How would that effect resolution when...
I thought there might be more theoretical physicists here, you guys as asking me to prove that outside light effects how much you can see when you have a telescope in your avatar? The pinhole would gather more information for the same reasons they build telescopes on Mauna Kea.
You do know...
What is the correct method of how the ""pinhole technique"" works?
And I disagree with your statement that the pinhole method is not all that useful for seeing without glasses.
I am getting my information from "my understanding" which I listed in my post. So you disagree that if limits the...
Some of you may have see the pinhole method of seeing without having to use glasses.
My question is this, could this same pinhole application of viewing clearly be useful in optical microscopes? And if so, can it be used in series?
By my understanding the pinhole technique works by...
