its good so far however I ordered it because it said it was $10.00 a month and it turned out to be $30.00, I guess that's only if you pay for the year it would've been nice had that been made clear before I put in my cc info

I like it but I wish I could just change out a document using the same link to share without having to create a new document.

For pdfFiller’s FAQs

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.

What is diffraction limited resolution?

An optical system with the ability to produce images with angular resolution as good as the instrument's theoretical limit is said to be diffraction limited. The resolution of a given instrument is proportional to the size of its objective, and inversely proportional to the wavelength of the light being observed.

What is meant by the diffraction limited resolution of a telescope?

angular resolution. ability of a telescope to distinguish between adjacent objects in the sky. diffraction-limited resolution. theoretical resolution that a telescope can have due to diffraction of light at the telescope's aperture. depends on the wavelength of radiation and the diameter of the telescope's mirror.

What do we mean by diffraction limit of a telescope?

What is the diffraction limit of a telescope? The minimum angular separation of two sources that can be distinguished by a telescope depends on the wavelength of the light being observed and the diameter of the telescope. This angle is called the DIFFRACTION LIMIT.

What is meant by the resolution of a telescope?

The resolution, or resolving power, of a telescope is defined as being the minimum angular separation between two different objects which can be detected.

How do you find the diffraction limit of a telescope?

The diffraction limit is defined by the equation =1.22 /D, where is the angle you can resolve, is the wavelength of the light, and D is the diameter of your objective mirror (lens). The maximum resolution that can be achieved by any optical system is set by the diffraction limit.

How does diffraction affect resolution?

Diffraction causes points of light which are close together to blur into a single spot: it sets a limit on the resolution with which one can see. if the light passes through a circular aperture.

How does magnification affect resolution?

A simple answer is that resolution of an optical system is its ability to separate two closely spaced objects. Resolution In general as the magnification increases the resolution increases, however, this much more complicated than it seems.

What does resolution depend on?

The limit of resolution (or resolving power) is a measure of the ability of the objective lens to separate in the image adjacent details that are present in the object. The wavelength of light is an important factor in the resolution of a microscope. Shorter wavelengths yield higher resolution.
