What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Very happy. Makes my documents look so much nicer and since I have neuropathy in my hands, it decreases my pain on a regular basis (way easier to type than hold a pen or pencil). Thanks SO much.

It was really easy to use the very first time I used it. It is also cloud based so if I need to use it on a different computer, all I have to do is log in on that computer.

PDFfiller came in very handy, especially with the ability to fax. Recently, I had to complete documents on behalf of my mother after my father passed away. I was limited because she had no internet, so I purchased a portable MIFI and once I realized that I could fax with PDFfiller, this eliminated the need to spend money on faxing & postage.

I'd rather pay per document. I don't need the subscription and will likely cancel after this transaction. Consider offering a cheap per-page service in the future.
2016-01-05
I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

How to send a fillable document that can be returned in a completed state
I am new to using the pdf filler application in my business. When I sent my first document out, my client had a problem returning the filled out document. I used the chat feature to resolve my problem and received excellent help from Sam, who answered my questions and provided me with great resources.

How do you increase the resolution of a microscope?
One way of increasing the optical resolving power of the microscope is to use immersion liquids between the front lens of the objective and the cover slip. Most objectives in the magnification range between 60x and 100x (and higher) are designed for use with immersion oil.
What is the resolution of a light microscope?
The maximum magnification of light microscopes is usually ×1500, and their maximum resolution is 200 nm, due to the wavelength of light. An advantage of the light microscope is that it can be used to view a variety of samples, including whole living organisms or sections of larger plants and animals.
What is the resolution limit of a light microscope?
The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. When we can see green light (0.5 Am), the objects which are, at most, about 0.2 Am.
What is the resolution or resolving power of a microscope?
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. It is the distance between two points in the object that are just resolved in the image.
What factors affect resolution of a microscope?
The primary factor in determining resolution is the objective numerical aperture, but resolution is also dependent upon the type of specimen, coherence of illumination, degree of aberration correction, and other factors such as contrast-enhancing methodology either in the optical system of the microscope or in the
How can the resolution of a light microscope be improved?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
Why is the resolution of the microscope more important than magnification?
While bigger is often better, magnification can be meaningless if the necessary resolution is lacking as Jackson once again demonstrates. So, resolution is the ability of a system to define detail, and this becomes increasingly important the more you magnify something.
What's the difference between magnification and resolution on a microscope?
Magnification is the ability to make small objects seem larger, such as making a microscopic organism visible. Resolution is the ability to distinguish two objects from each other. Light microscopy has limits to both its resolution and its magnification.
