For the Airy disk radius, the formula is (1.22 * wavelength * F/#). For the same parameters, this gives 19,73µm, which is also what I get from Zemax. This means the Airy diameter is 39,46µm, which is about twice the size of the focal spot size calculated with the generally used formula to calculate the focal spot size.

Conversely, the ocular lens, also known as the eyepiece, is situated near the observer's eye. Its primary function is to further magnify the image produced by the objective lens. Ocular lenses are often interchangeable, allowing users to customize their viewing experience based on desired magnification. The most common magnification for a microscope ocular lens is 10x. Additional magnifications of microscope ocular lenses include 12.5x, 15x, and 20x.

When it comes to optical instruments like microscopes and telescopes, the objective lens and ocular lens play distinct roles in shaping our viewing experience. Understanding the differences between these crucial components is fundamental to unlocking the full potential of these devices.

Thank you for your reply. I also was thinking that the first formula should be applied on the beam waist radius, but in a lot of sources (not from zemax but elsewhere) they are using it as diameter. So that’s why I was somewhat confused about it.

This guide will break down the differences between various digital camera sensor types and sizes, and explain how they affect your photography.

Understanding the numerical aperture of the objective lens is crucial, as it determines factors such as resolution and depth of field. The ocular lens complements this by providing additional magnification, allowing for intricate examination and analysis.

For this there is a standard, generally used formula: (M² * focal length * wavelength) / (pi * aperture). For parameters 980nm wavelength, 330mm focal length and aperture 20mm, this gives 20,6µm.

Objective lensmagnification

The objective lens is the primary magnifying element in optical instruments. Positioned closer to the object being observed, it captures and magnifies the incoming light, bringing the specimen into focus. The objective lens is characterized by its varying magnification levels and includes the numerical aperture of the objective.

To achieve optimal magnification and clarity, the objective lens and ocular lens must work in harmony. The process begins with the objective lens capturing light from the specimen, forming an intermediate image. This image is then further magnified by the ocular lens, delivering a detailed and enlarged view to the observer.

The objective lens and ocular lens are indispensable components in optical instruments, each contributing uniquely to the observation process. Recognizing their differences and understanding how they collaborate enhances our ability to explore the microscopic world with precision and clarity.

I think the first formula you referred to should be applied on the beam waist radii and not on the full aperture diameters, please see this reference below:The beginner's guide on spot size of laser beam (gentec-eo.com)
