What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
The service works well and is very convenient, however I was disappointed by the way I was able to complete an entire form but was not advised it was not free until the form was completed after spending a couple hours working on it. Since this is a pay service, the consumer should be advised immediately upon accessing any forms on an internet search. In order to preserve my work, I had no choice but to subscribe. Perhaps you should market a new service that charges by the document. I would have gladly paid for that up front. The service itself works very well.

Easy to use, but seems like a lot of steps to go through to get to the documents and to save them to my computer. I have to save it to my computer to print it because printing from the program doesn't get it all printed on the 8.5x11" paper so leaves information off.

I'm impressed with PDFfiller but I think there could be more options of background colours of the textbox, including different shades within each color.

Great tool in a pinch!
The google chrome extension worked really well since you can't just click on something in drive and easily open it - and I've had issues with Adobe for some time. This software did what I needed it to do multiple times.
This is typically slow to open, and saving & retrieving files is a bit clunky.

Great Customer Service
I was checking out pdfFiller to help with a project I was working on. I must have started a free trial and forgot to cancel. I received a charge for an annual subscription via paypal. Customer service was quick to give me a refund for the mistake. The agent was amazing. Helped me right away, issued a refund. Wow! Best CS I have ever received. Thanks so much.

What is the resolution of a confocal microscope?
When optimally used, confocal microscopes may reach resolutions of 180 nm laterally and 500 nm axially, however, axial resolution in depth is often impaired by spherical aberration that may occur due to refractive index mismatches.
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 maximum resolution in micrometers of a light microscope?
That's right, when using visible light through a light microscope, the limit of resolution is about 0.2 m.
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 magnification of a confocal microscope?
This first-generation instrument images corneal structures at ×400 magnification and has a field of view of 400 A 400 Am when used with a Ã63 objective lens that has a numerical aperture of 0.9. It uses a 670 nm red wavelength Helium-Neon diode laser as its illumination source.
Why would you use a confocal microscope?
Most confocal microscopes used in industrial applications are reflection-type. They provide a high-resolution image with all areas in focus throughout the field of view, even for a sample having dents and protrusions on the surface. They enable the non-contact non-destructive measurement of three-dimensional shapes.
What can be seen with a confocal microscope?
Commercial spinning-disk confocal microscopes achieve frame rates of over 50 per second a desirable feature for dynamic observations such as live cell imaging. In practice, Nikon and PAM allow multiple pinholes scanning the same area in parallel as long as the pinholes are sufficiently far apart.
