What is the depth of field on a microscope?
Depth of field is the axial depth of the space on both sides of the object plane within which the object can be moved without detectable loss of sharpness in the image, and within which features of the object appear acceptably sharp in the image while the position of the image plane is maintained.
How much does a microscope lens cost?
This microscope is priced at $1305.00 here and does not include a camera. At this price point and the fact that it comes with achromatic objective lenses you are paying a steep price for the brand name, quality and warranty that the brand provides….

What is the depth of focus of optical microscope?
The focal depth refers to the depth of the specimen layer which is in sharp focus at the same time, even if the distance between the objective lens and the specimen plane is changed when observing and shooting the specimen plane by microscope.
What is the field of view of a microscope at 40x?
Stage micrometer at 1000x magnification with Olympus Compound Microscope. The diameter of field of view (fov) is 0.184 millimeters (184 micrometers)….
Objective | Diameter Of Field Of View | Magnification (10x Ocular) |

How to calculate depth of field in a microscope?
Where d is the depth of field, λ is the wavelength of the illuminating light, n is the refractive index of the medium, NA is the numerical aperture of the objective lens, M is the lateral magnification of the lens, and e is the smallest resolvable distance of a detector on the image plane.
What are the dimensions of an Olympus microscope?
Objective lens U-TLU (Single port tube with lens) Image Recommended distance 50-170mm * 40mm 45mm * 84mm 57.6mm 102mm *Basic dimensions when our revolving nosepiece and illuminator are combined. When the position of the illuminator above is changed, illumination performance cannot be maintained.
What is the resolution of a diffraction limited microscope?
Resolution for a diffraction-limited optical microscope can be described as the minimum detectable distance between two closely spaced specimen points: where R is the separation distance, λ is the illumination wavelength, n is the imaging medium refractive index, and θ is one-half of the objective angular aperture.
Which is the least expensive objective for a microscope?
In cases where the light level is a limiting factor, choose an objective with the highest numerical aperture, but having the lowest magnification factor capable of producing adequate resolution. The least expensive (and most common) objectives, employed on a majority of laboratory microscopes, are the achromatic objectives.
