Also referred to as camera resolution, the number of pixels represents the maximum size of images which can be displayed or recorded by a camera. The value is displayed using MP (megapixels).

Various types of cameras are available. Cameras intended to be used with computers will use USB, wi-fi, or LAN to connect to the computer, and typically include specialized software. Cameras with HDMI, VGA, or analog video interfaces can be attached directly to a compatible display device such as a monitor or television, and do not require a computer to operate.

Magnification can represent combinations of lenses including objective, ocular, and auxiliary lenses. The magnification ranges described here may include these combinations.

This is a 50mm (2") microscope substage mirror with a 5mm diameter pin and a black disc (41.5mm mounting thread). It is convenience if there is power failure or you are in the field and no power is available. You can get reflected ambient light on either side of the mirror with different angles for best result.

The above formula was derived for diffraction grating, but it can also be used for other purposes. Lord Rayleigh stated that two light sources are regarded as resolved when the principal diffraction maximum of one image coincides with the first minimum of the other.

We can compare this result with the Hubble space telescope, which has a mirror of diameter 2.4 m (it collects light just like the eye pupil). The estimated angular resolution equals θ ≈ 0.000016° – it is 125 times better than our eye!

The smaller the angular resolution is, the more details you can see. It is essential when designing microscopes, telescopes, or cameras. Even the human eye has its angular resolution!

Angular resolution is the capacity of an optical instrument to separate two objects that are located at a small angular distance. In other words, with this physical quantity, you can check if you can:

Angular resolution is sometimes called the Rayleigh criterion. The famous physicist, Lord Rayleigh, has proposed an empirical angular resolution formula:

The diameter of an eye pupil (our natural lens) changes during the day and night, but it is approximately 2 mm on sunny days and 8 mm at night. Let's assume that we will try to resolve points that are green; the wavelength of green light is equal to λ ≈ 550 nm. With the Angular resolution calculator, we compute that the angular resolution during the day is θ ≈ 0.02°.
