NA is the Numerical Aperture. In most cases the material between the objective and sample is air, and “n” equals 1.00. For water, it’s refractive index is 1.33, and specialized immersion oil for microscopy is 1.52. For a low magnification objective such as a 4X or even a 10X, the typical depth of field is plus or minus 3 to 5 microns.

CFI Apo 40xWI λS has an NA of 1.25, the world's highest for a 40x water immersion objective. Ideal objectives for confocal imaging. CFI Apochromat λS Series. 7. 6.

There might be a macro-objective out there with wide FOV while still retaining a decent NA. I know Nikon made a system called the AZC2+ which was a large area confocal. I'm sure other vendors have similar. NA is the Numerical Aperture. In most cases the material between the objective and sample is air, and “n” equals 1.00. For water, it’s refractive index is 1.33, and specialized immersion oil for microscopy is 1.52.

Scanning Objective Lens (4x) Combined with the eyepiece lens, this lens will provide the lowest magnification power. Numerical Aperture. Numerical aperture (NA) is defined as being equal to n sin θ, where n is the refractive index of the medium between the objective lens and the object (n≅1 for air) and θ is half the angular aperture (or acceptance angle of image-forming rays) of the objective lens (Jenkins and White 1957).

A Objective é feita de pessoas. Se hela listan på microscopyu.com Consequently, the high-NA objectives are those which use an immersion medium in place of air, such as oil or water. In reality, an NA of one with air between the specimen and the objective front lens is unachievable and therefore the highest NA of a ‘dry lens’ (i.e. a non-immersion objective) and is closer to 0.95.

Obviously, a high-NA objective can collect more light than one with a low numerical aperture. The NA of an objective is an important aspect and relates to the image resolution. In brief, the resolution is the ability of the objective to distinguish details in your specimen.

The optimized NA of 0.8 provides improved light gathering, with a working distance of 0.7 mm. White Light Interferometry Objective. Lens Type: Objective Lens Magnification: 100 X; Numerical Aperture: 0.8000 NA Microscope objective with the highest numerical aperture, broadest chromatic correction, and a temperature calibrated correction collar to eliminate spherical aberration. Nikon's CFI Apochromat TIRF Series Objective Lenses have the highest NA available using standard immersion oil and glass coverslips. The NA of such an objective lens is determined in accordance with a data density of a recording medium. For example, the NA of an objective lens of an optical pick-up for a CD (compact disc) is approximately 0.45. The NA of the objective lens for a DVD (digital versatile disc) is approximately 0.6.
