What do you like best?
PDF Filler is super simple to use. I love that you can just click where you need to put information (whether it’s a checkbox, words, etc) and it’s done. If you have a form that you use often you can even save it as a template so you don’t have to go back in and create new boxes each time.
What do you dislike?
I’ve had a few issues with the site being down but this only lasted for short periods of time. Otherwise, the product itself is fantastic.
What problems are you solving with the product? What benefits have you realized?
Instead of needing to print forms out, we are able to fill them out online, at a cost effective price. Saving us paper, ink and time.

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in ****** and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund.I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.

My printing is horrible. This allow me to fill out legal forms without having to do them over and over. I will say getting the cursor right where you needed it was difficult.

JUST AS GOOD OR BETTER THAN ADOBE PDF AND CHEAPER
Used for filling out electronic documents, easier than filling out documents manually and then having to scan them in order to email them.
Easier to use than adobe PDF, at a better price.
No complaints about this software as the time of me reviewing it, so far very content with it.

What is meant by limit of resolution?
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. ... Thus, an optical system cannot form a perfect image of a point.
What is the limit of resolution of a microscope?
Lateral resolution in an ideal light microscope is limited to around 200 nm, whereas axial resolution is around 500 nm (for examples of resolution limits, please see below).
What is meant by limit of resolution of a microscope?
Resolution and Imaging. 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 is the resolution of a microscope?
The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
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 ...
What is limit of resolution of telescope?
It is defined as the inverse of the distance or angular separation between two objects which can be just resolved when viewed through the optical instrument. Thus, higher the diameter d, better the resolution. The best astronomical optical telescopes have mirror diameters as large as 10 m to achieve the best resolution.
What is the definition of resolution in microscope?
The resolution of an optical microscope is defined as the shortest distance between two points on a specimen that can still be distinguished by the observer or camera system as separate entities.
What is resolution in a microscope?
In microscopy, the term 'resolution' is used to describe the ability of a microscope to distinguish detail. In other words, this is the minimum distance at which two distinct points of a specimen can still be seen — either by the observer or the microscope camera — as separate entities.
What is magnification and resolution of a microscope?
Key Points. 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.
Which light gives the best resolution in a microscope?
The greatest resolving power in optical microscopy requires near-ultraviolet light, the shortest effective visible imaging wavelength. If a red light is replaced by a blue light illuminating an object in a microscope, then will the resolving power of the microscope be increased or decreased?
