This is so much easier to fill out applications instead of printing them and faxing.. I am happy I can fill out all my applications online and send them without worrying about if they were received or not.

wasn't aware i was paying for it until i saw the charge on my bank statement. that should have been clearer. will know more about how much i like it when i print the documents i have entered. i also would like a tech support number as i am very bad with computers.

It's incredibly easy to use! I *love* that I don't have to print this stuff out and fill it in by hand anymore. And making edits to what I do is super easy too! I'm so glad I found this website!

I was skeptical at first, but eventually got the hang of it. Now, I pleased to say, this is valuable website for filing documents and important papers. Thank you.

Even Adobe editor couldn't help
I needed to change one document and even adobe software couldn't help. The only possible way was to sign up for a free trial. I forgot to end the trial and when I was charged, I contacted the support centre and they return me my money straight away. Very happy with the product and their support service. Would be happy for an option to pay for a single-use, as I'm editing pdf files only a few times per year.

Could be worse for this price
I was expecting that it will be worse because I have seen a lot of weird and bad reviews. Especially in their Google extension market. But it works not bad, actually. I can recommend it.

I needed to create a document and sign it in a hurry. I already own Turbo PDF, but, its confusing to use.
I did a quick Google search and down loaded Pdf filler and had my doc printed in less than 10 min!
It works for me.

I filled out forms before purchasing app and thought it was saved. After I purchased the app I could not find my document. I texed with a customer service rep, he was no help and quit the communication.

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 is the 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. In this equation, the computed angle is in radians.
What is meant by resolution of a telescope?
The angular resolving power (or resolution) of a telescope is the smallest angle between close objects that can be seen clearly to be separate. Resolution is limited by the wave nature of light.
What does diffraction limited mean?
Diffraction limit means that an imaging lens could not resolve two adjacent objects located closer than /2NA, where is the wavelength of light and NA is the numerical aperture of the lens. E.g. the resolution of optical imaging instruments, is fundamentally limited by the diffraction of light.
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.
Why do you think this limit of resolution is described as diffraction limited?
There are many situations in which diffraction limits the resolution. The acuity of our vision is limited because light passes through the pupil, the circular aperture of our eye. Be aware that the diffraction-like spreading of light is due to the limited diameter of a light beam, not the interaction with an aperture.
What does it mean to be diffraction limited?
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.
