Very User Friendly and convenient. Wish there was other nursing cheat sheets available. ( Treatment sheets, Vital assessment sheets, etc) Takes the guess work out of creating your own.

What a life-saving tool. I have saved countless hours of waiting for forms to be returned or having to find forms to complete before sending. One stop service here. Find the form, fill it out online, forward it to its intended. Has been a Godsend with Court Documents.

I had some issues with establishing connections, but when I chatted with Paul, he had the solution for downloading the form in less than 3 minutes! This was a truly a great experience for me!

Some issues with editing documents
Some issues with editing documents. A specific example is that it can be hard to remove checks and X's from document, but overall one of the best document editors i have used.

Hands down the best pdf editor period. I was able to white out and edit my document. No other application has given me this ability and it saved me so much time.

easy to use
easy to use, it would be good if you could copy text and paste it i might not have worked out how to do that yet if its there, and insert signature would be helpful, that might be there already but i couldnt find it otherwise its easy to use and easy to send documents

Very helpful customer service experience
Very helpful customer service experience! Used the chat function on the website and Sam was quick and efficient to respond and my issue was instantly solved. Very refreshing as so many many companies leave you on hold for hours or don't reply at all!

pdf Filler is surprisingly worth the investment
pdf Filler is surprisingly worth the investment. I don't have a PDF application on my computer, so having one online that I can easily use to view, fill, and send documents has been a huge help for work and personal use.

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.
