What are Optical Grade Germanium (Ge) Wafers?

Germanium (Ge) is used in optical designs where a high index is required, such as for highly efficient infrared imaging. Germanium has proven to be an ideal material for a wide range of optical applications, from low-energy imaging to high-efficiency spectroscopy. In the range of 2 - 12 Wei m, germanium is one of the most widely used materials for the production of ball lenses and is also used for optical design where high indices are required.

Quantum cascades for the production of ribbons - structural engineering with QC lasers offers a wide range of applications in the field of high-performance materials and materials science and technology. They can be found at the Max Planck Institute of Quantum Optics in Garching as well as at a number of universities and research institutes in Germany and around the world. The Quantum Cascade for the manufacture of strip structures for the technique produced with quantum cascade lasers (QC) offers a wide range of applications for a wide range of applications, such as strip structure and materials science, but also for the development of new materials for use in medical applications.

The transmission curve at the top of the next page shows the transmission curves of a quantum cascade laser beam in a band structure. The largest elements have been produced so far: surfaces 12 and 15 mm long with an optical axis running parallel to the edge 15 mm long, 5 mm of which are in the beam path and which are polished at 20 - 10 s / d. [Sources: 5, 6]

This number refers to the deviation from the ideal plane surface and is measured by measuring the distance between the edge of the beam path and the surface at 20 - 10 s / D. D., London. This number is considered sufficiently accurate to extrapolate up to 40um. The calculations and equations can be evaluated as long as there is no deviation of more than 20um from an ideal surface of 15 mm length and 5 mm width. [Sources: 0, 3]

It is recommended to use antireflective coatings and has minimal chromatic aberration due to low dispersion. Standard Optical Grade Ge has a temperature of 10 - 6 - 25 C and should also be easily accessible for images with a wide wavelength range from 0.5 - 10 mm to 100 - 200 mm. It can also be imaged with high resolution at a resolution of 1,000 - 2,500 pixels. [Sources: 0, 3, 5]

The growing need for data to send and receive drives the need for germanium to be incorporated into more fiber optic cables. [Sources: 1]

UV-transmitting substrates, UV-compatible quartz glass (UVFS) are the most widely used substrates and excimer-compatible FS is used in applications up to 193 nm. In cases where low UV transmission is required, mgf2 is often used because it has the best transmission at shorter UV wavelengths. We offer a wide range of high quality germanium crystal components for use in your products and are available in a variety of shapes, sizes and shapes in various shapes and sizes. [Sources: 2, 8]

The prism can be made of almost any material that can effectively transmit the wavelengths required for certain applications. The polarized optical cube prism insulator consists of a combination of germanium (Ge) and silicon (Si) in the form of a hexagonal prism. [Sources: 6, 7]

The optical component is available in various shapes: electroplating is able to guide N - BK7 silicon lenses in convex and concave formats. [Sources: 4, 7]

Germanium (Ge) is one of the most popular materials in the field of infrared applications. Tydex uses germanium, which has the best transmission in the range of 2 - 15% and is also used in other applications. [Sources: 0, 4]

The fluoride, which is discussed in the UV, VIS and NIR substrate sections, also transmits infrared light (approx. 5%). This means that it has the same IR transmission characteristics as ZnS, but can also transmit the full VIS / Nir spectrum. Ge is a good choice for systems that operate in a wide range of wavelengths, such as infrared, ultraviolet, visual and UV light. [Sources: 5, 8]

This is because it can be embedded in a wide wavelength range such as infrared, ultraviolet, VIS and NIR. [Sources: 4, 5]

Due to their high refractive index, Ge-lenses are ideal for IR imaging systems operating in Huo Yuan's atmospheric windows. Huo Yuan meniscus lenses are made from AMTIR C1 germanium substrates with coating. Due to the higher refractory index, they are suitable for an IR imaging system that works on atmospheric windows from 3.5 to 8 to 12 micrometers. [Sources: 2, 4, 6]
