Your service is amazing and I spoke with the kindest gentleman who so graciously helped in my time of need. Ray I believe was the representatives name. I am unemployed single mother of 2 boys going through a nightmare of a custody battle with my x husband. I was confused and distraught and having trouble finding fillable forms online. Ray was my angel. Promote him! Exlnt.customer service skills. Thank You Ray, Kristi Waters

PDF filler seems to be very useful. Is/was slightly difficult to figure out but once understood is fairly easy to use. Unfortunately the price is too high for those of us on fixed income. Is there anything lower cost for disabled seniors? Please?

just started using the product and it works very well. The only thing is that I will use it for the forms I need to fill out and then will cancel since I won't need to use the product after 30 days. You should have a one time fee.

I feel that it was inappropriate and a bit shady to let a customer edit the PDF and then hit them with the credit card ask. Maybe let them do a test for 15m or something.

I probably would have continued if I was given a reasonable monthly option. I do have a few subscriptions that I keep on a monthly option. So, keep that on mind when you are working with teachers.

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.
Equation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 (where is the standard deviation) and the peak FHM is W0. 5h = 2.354.
NA= n x sin Where n is the refractive index of the imaging medium and is half of the angular aperture of the objective. D= /2 NA. Where is the wavelength of light used to image a specimen. D= 2 /NA2 R= 1.22 /Naomi+Second.
Abbé's equation. This is the diffraction-limited resolution of an optical system. If all aberrations and distortions are eliminated from the optical system, this will be the limit to resolution. If aberrations and distortions are present, they will determine the practical limit to resolution.
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
The resolution limit of light microscopes is about 200 nm, the maximum useful magnification a light microscope can provide is about 1,000x. The resolution limit of electron microscopes is about 0.2 nm, the maximum useful magnification an electron microscope can provide is about 1,000,000x.
A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×.
The wavelength of electrons is thousands of times shorter than visible light, Hence electron microscopes would be able to resolve objects that are thousands of times smaller. The electron microscope has a high-resolution power. This is due to the very low wavelength of the electron beam.
