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.

Abbe described a microscope system by defining resolution in terms of wavelength, where d, or the smallest measurable object, is a function of wavelength and objective NA. The numerical aperture of an objective depends on the half-angle of the aperture.

Types of Objective Lenses. The majority of compound microscopes come with interchangeable objective lenses, which have different magnification powers. This commonly includes 4x, 10x, 40x, and 100x objective lenses. Scanning Objective Lens (4x) Combined with the eyepiece lens, this lens will provide the lowest magnification power.

Immersion medium is used to alter the refractive index of the space between the objective and glass coverslip so that it is closer to the refractive index of the glass coverslip itself. 2018-09-11 Olympus na objective Na Objective, supplied by Olympus, used in various techniques. Bioz Stars score: 90/100, based on 23 PubMed citations.

A high numerical aperture (NA) is important for TIRF microscopy. As a pioneer in TIRF microscopy, we advanced our lens polishing technology to create the world’s first plan-corrected apochromat objectives with an NA of 1.5. Objective Manager builds performance management and strategic planning software to align behaviours with firm-wide goals. OKR for law firms and professional services. Where d(tot) represents the depth of field, λ is the wavelength of illuminating light, n is the refractive index of the medium (usually air (1.000) or immersion oil (1.515)) between the coverslip and the objective front lens element, and NA equals the objective numerical aperture.

The oil is applied to the specimen (conventional microscope), and the stage is raised, immersing the objective … The shortest objective length is 10.8mm for 2X magnification, while the longest objective length will be roughly 180mm for 20X magnification. TECHSPEC Ultra Compact Objective Assemblies base optics utilize two different numerical apertures and two different focal lengths for four objectives, with two different working distances of 9.9mm and 11.4mm respectively.

Consideration of the vectorial nature of light in the simulation of the focusing is therefore fundamental. VirtualLab Fusion supports both ray and field tracing analysis of such lenses with great ease.

The main objective of this study was to quantify the amounts of major elements, such as Ca, Mg, Na, S and Cl carried by process water and by magnetite grain

This forms a coarse structure that lowers the reflectance index, facilitating the passage of light through the lens rather than reflecting it, and thus providing superior light transmission.

The Zeiss 40X (0.75NA) Plan-Neofluar objective lens for the Thermo Scientific ArrayScan HCA Readers is made by the world renowned optics company, Zeiss. The Zeiss 40X (0.75NA) Plan-Neofluar lens represents the finest in optical with a magnification power suited for subcellular imaging, and a numeric

A high-NA objective typically contains a more complicated combination of various types of lenses of hemispherical, meniscus, achromatic doublet and triplet type. There are also reflective objectives, containing curved mirrors and no lenses. 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). High-NA metrology architecture.
