A Great Source for Reference
As soon as I came across PDFFiller I immediately subscribed. Any time I need to make a fake document for a Movie or TV show I go right to the site and look up what I'm trying to mimic. 9 times out of 10 I find what I need.
I love PDFfiller because it provides me with a wealth of real life uploaded document references for any design I may be trying to mimic.
The search feature could be a little better.

Basic PDF Editor
I use it for PDFs for our Escrow files. We have clients sign docs and we can make changes to anything that they send us and then send to them to sign off on it
It is easy and very good for a basic PDF editor. You can make simple changes and save it so it looks exactly like a PDF should. You can add and edit text, highlight, adjust sizing, etc.
It is too basic but i understand that it is not Adobe. I wish I could edit the text that is in the PDF more easily to make it match and all look seamless

How can you increase the resolution of a light microscope?
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.
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.
How do you improve eye resolution?
In order to increase the resolution (d=/2 NA), the specimen must be viewed using either shorter wavelength () light or through an imaging medium with a relatively high refractive index or with optical components which have a high NA (or, indeed, a combination of all of these factors).
What is the resolution of the human eye in pixels?
According to scientist and photographer Dr. Roger Clark, the resolution of the human eye is 576 megapixels. That's huge when you compare it to the 12 megapixels of an iPhone 7's camera. But what does this mean, really?
