All branches of biology use Microscopes especially in Molecular Biology and Histology (the study of cells). Microscopes are the backbone of studying biology. The biologists use them to view the details that cannot be seen by the naked eye such as the small parasites and small organisms which is important for the disease control research.

The use of a diffractive lens as a flat optical element can be beneficial in order to limit the volume of a conventional optical system and correct chromatic aberration.

The simplest DOE profile is binary: two profile planes produce the required phase shift of the light. Multi-stage profiles with a single grating period allow for more precise phase control.

Electron microscopes help prepare the small surfaces for sectioning into small slices. Microscopes enlarge the images of silicon chips to help the engineers create more efficient electronic devices. When more circuits are fitted onto a small chip, the computational power of silicon microchips increases.

Microscopic examination confirms the laboratory tests that may be positive for the disease. Technicians count the number of red blood cells infected with the virus or parasite to give the doctors an idea of how advanced the disease is in a patient.

The combination of writing process, development process and etching process at ZEISS delivers precise results with very low roughness. These low-scatter, diffractive, optical elements with sub-nanometer roughness baseline are beneficial in certain applications.

Our gratings have various application possibilities. They are used for spatial splitting of spectral light components or find application as imaging, beam shaping and beam splitting.

Generation of arbitrary far-field profiles with a well-defined angular distribution for partial incoherent light. Corresponding diffractive diffusers are used in laser lighting applications, among others.

Scanning electron microscopes have magnifications up to several million times to view the molecules, the viruses and the nano-particles. They use the corrective software to increase the magnification and the resolution of images. The computers help the nano-technologists use high-powered electron microscopes to view the objects.

When it comes to biology, Microscopes are important because biology mainly deals with the study of cells (and their contents), genes and all organisms. Some organisms are so small that they can only be seen by using magnifications of 40x-1000x, which can only be achieved with the use of a microscope. Cells are too small to be seen with the naked eye.

Apart from biological research use and industrial use, Microscopes are also used in the field of genetics. Genetics is the study of variations in an organism generation after generation. Genetic engineering requires the mixing of genes. Genes are even smaller than cells, which is why microscopes are essential in this field.

Microscopes are not just used to observe cells and their structure but are also used in many industries. For example, electron microscopes help create and observe extremely tiny electrical circuits found on Silicon microchips. Scanning microscopes are much more sophisticated and they have higher magnifications than light-refracting microscopes.

Microscopes use the simple visible light refracting lenses. Electrons, x-rays and infrared rays Scanning electron microscopes are able to resolve the viruses which are far smaller than any cell. They enlarge the view of tiny viruses, which allows scientists to develop the vaccines and cures for infectious diseases in the humans and the animals.

Diffractive optical elements (DOE) diffract light at the microstructured surface. Thanks to their high level of functionality, several optical functions can be integrated simultaneously in a single element. DOEs thus enable very compact, lightweight and elegant practical solutions, which with purely refractive macro optics, are only possible at a very high cost.

Microscopes are also used to diagnose illness in hospitals and clinics all over the world. Microscopes magnify the blood samples, so the doctors or the pathologist can see the viruses and the parasites attacking the red blood cells and take the necessary steps to cure it.

Diffractive optical elements (DOEs) are optical components that deflect light into multiple orders at precise angles. Periodicity and their spatial frequencies, rather than the surface topography profile, determine the optical performance.

From regular periodic micro-lens arrays to randomized continuous phase profiles, Advanced Optical Technologies, Band 4, Heft 1, Seiten 47–61, eISSN 2192-8584, ISSN 2192-8576, DOI: https://doi.org/10.1515/aot-2014-0062

Microscopes have opened up many doors in science. By using Microscopes scientists, researchers and students were able to discover the existence of microorganisms, study the structure of cells and see the smallest parts of plants, animals and fungi.
