Establish Formula Resolution For Free

Lateral resolution is approximated by the ? 6 dB full-width half-maximum beam profile, given by LR = 0.4 × ? × F/L, where LR is the lateral resolution, ? is the ultrasound wavelength, F is the focal depth, and L is the active aperture length [20]. So, the greater the aperture, the better the LR.

Resolving power of a microscope is a function of refractive index. The resolution limit of a microscope is the shortest distance between two nearby objects when the images formed by the microscope are properly differentiated. The resolving power of the microscope is Xmin = 1.22?/ numerical aperture.

Low Power Objective (10x) The total magnification of a low power objective lens combined with a 10x eyepiece lens is 100x magnification, giving you a closer view of the slide than a scanning objective lens without getting too close for general viewing purposes.

The resolution of a microscope objective is defined as the smallest distance between two points on a specimen that can still be distinguished as two separate entities.

In our lab a 10x objective has a resolution of 0.7 microns and a 100x objective has a resolution of 0.2 microns. One other tradeoff to consider: higher magnification lenses look at smaller fields of view, in proportion to their magnification.

The 10x objective provides 0.92um resolution. The 40x objective provides 0.37um resolution. The 100x objective provides 0.21um resolution.

In order to increase the resolution, d = ?/(2NA), the specimen must be viewed using either a shorter wavelength (?) of light or through an imaging medium with a relatively high refractive index or with optical components which have a high NA (or, indeed, a combination of all of these factors).

In the case of a monitor with an industry-standard Full HD 1080p resolution, this display has a resolution of 1920 x 1080. This means that the screen will have a width of 1,920 pixels while the height of the screen will be 1,080 pixels.

? = 1.22?/ D where is the wavelength of light (or other electromagnetic radiation) and D is the diameter of the aperture, lens, mirror, etc., with which the two objects are observed.

The resolution of an optical microscope is defined as the smallest distance between two points on a specimen that can still be distinguished as two separate entities.
