Mirrorless camera is the current popular type of camera in the market. The mirrorless camera will not have an optical viewfinder. Instead, it will have an electronic viewfinder. This removes some amount of weight from the camera body.

It's important to note that the working distance can vary depending on the specific microscope model and the magnification being used. Higher magnifications often result in shorter working distances.

This feature makes smartphone cameras more attractive to people who are looking for DSLR camera features in a compact size.

The refractive index of the medium is the index of refraction of the material between the objective lens and the cover glass, typically air or immersion oil. The thickness of the cover glass and specimen are the physical dimensions of these components.

The numerical aperture is a measure of the lens's ability to gather and resolve light. Higher numerical aperture lenses generally have shorter working distances. Therefore, as the magnification and numerical aperture increase, the working distance tends to decrease.

They are a little heavy and bulky when compared to the DSLR/ Mirrorless cameras. The bulkiness is mainly due to the large camera sensor.

DSLR gives you the ability to record images in RAW format. You can later post-process images in Adobe Photoshop or Lightroom.

Rugged cameras are shockproof and waterproof cameras. Specification wise, it is similar to a point and shoot digital camera.

In conclusion, to calculate the working distance of a microscope, one needs to know the tube length and the objective lens length. By subtracting the objective lens length from the tube length, the working distance can be determined. However, it is important to consider other factors such as magnification, numerical aperture, and any additional accessories that may affect the working distance.
