WebThe highest angular aperture obtainable with a standard microscope objective would theoretically be 180 degrees, resulting in a value of 90 degrees for the half-angle used in … Web12 de jul. de 2024 · Numerical aperture (abbreviated as ‘NA’) is an important consideration when trying to distinguish detail in a specimen viewed down the microscope. NA is a …
WebObjective lenses of higher numerical aperture are capable of producing smaller Airy discs, and therefore can distinguish finer detail in the specimen. The limit at which two Airy discs can be resolved into separate entities is often called the Rayleigh criterion. Web11 de abr. de 2024 · Operating at a numerical aperture of 0.7 with 193 nm illumination from an ArF excimer laser, we have demonstrated lithographic optics with the highest nominal resolution to date.
Web19 de jan. de 2024 · The maximum angular aperture of an objective is around 144º. The sine of half of this angle is 0.95. If using an immersion objective with oil which has a refractive index of 1.52, the maximum NA of the objective will be 1.45.
