What is the purpose of the objective lens in a lightmicroscope

Optical glass starts as an ingot (shown on right) which is formed by blending rare earth elements and repeated melting, shaping and slow cooling to achieve a target refractive index. The glass ingots are precision-cut, polished and coated to produce lens elements for the objective.

Produced to exacting standards, Nikon’s objectives provide exceptional detail and clarity. The highest level of image quality can be achieved whether it be for routine tasks or cutting-edge research.

The UV range extends from 200 400nm, below human vision and in the responsivity of UV-optimized silicon detectors. Many applications have valuable spectral signatures in the UV region that can be evaluated using precisely positioned bandpass filters.

With over 100 years of experience in developing optical technology, Nikon offers a wide range of components that can fulfill almost any optical requirement.

What does the objective lens do on amicroscope

Each Nikon microscope objective is precision-crafted to provide the highest level of clarity and overall optical performance. World-class Nikon objectives, including renowned CFI60 infinity optics, deliver brilliant images of breathtaking sharpness and clarity, from macro- to nano-scale.

PIXELTEQs ultraviolet (UV) optical bandpass filters deliver precise transmission of specific UV spectral bands while blocking out-of-band signals at higher and lower wavelengths. The multi-edge bandpass filters transmit wavelengths defined by a nominal center wavelength (CWL) and bandwidth (FWHM – Full Width Half Max) while reflecting both shorter and longer wavelengths. Also known as thin film or interference filters, PIXELTEQs bandpass filters use multi-layer hard coatings that provide durable performance without fading or aging in high output luminaires.

Nikon's online Objective Selector tool enables you to quickly and easily find the right objective for your application. Refine your search based on application, technique, objective class, immersion type, etc. Specifications for multiple objectives can be displayed in a single window for easy comparison.

Bandpass filters are commonly matched or combined with other types of filters to optimize performance in your specific application. In many cases, an optimized OEM design combines multiple coatings onto the same optic to enhance performance, size, and weight of the device. Some of these complementary filter types include:

Nikon offers a broad portfolio of objectives to meet your individual application needs. Explore some of the different objective series in the following pages.

Unlike absorptive colored glass or polymer gels, these thin film interference filters are virtually absorption free providing superior transmission, high-contrast spectral bands, and true lifetime performance. Dichroic bandpass filters can be designed for narrow bandwidths (5 and 10nm typical) or wide bandwidths (50 and 100nm typical). They also have steep edge transitions between the high transmission bandpass and shorter and longer wavelength reflection bands much steeper than colored glass or polymer gels.

Confocal microscopy

The front lens of high-performance objectives is hand-polished by Nikon's most highly skilled experts (shown on right), a technique requiring more than a decade to master. By controlling the entire manufacturing process from glass formulation to assembly and alignment of lens elements, Nikon ensures the highest quality and performance of its objectives.

Nikon develops products to the highest standards, from design to manufacture, to ensure we meet the needs of a wide variety of customers.

Objective lenses are arguably the most important element in the microscope. Nikon has been developing optical technologies since 1917 with the establishment of Nippon Kogaku KK (Japan Optics). The JOICO microscope with interchangeable objectives and revolving nosepiece was first introduced in 1925. With over 100 years of dedication to the development of optics, Nikon continues to innovate and produce breakthrough optical technologies to help accelerate scientific research.

Nikon has been developing optical glass since its inception in 1917, and to this day, wholly owns and formulates all of its glass.

Custom spectral bands are available to match specific bandwidths and cut-on & cut-off wavelengths engineered for your specific application to deliver the targeted spectral output. These bandpass filters can be patterned on glass optics and wafer-level devices for integrated spectral sensing and imaging. Multiple bandpass filters can also be micro-patterned for multispectral sensing and imaging applications with potential combinations including UV and visible bands on a common Si sensor. In addition to customized coatings, the optics are delivered in the form to fit your application in specific substrates, shapes, and sizes.
