Germanium Lens


FEATURES OF GERMANIUM LENS 

Germanium lens are made using germanium material which is a relatively hard, of high density, IR transmitting material. This material can block UV and VIS wavelengths. On the side it can allow IR from 2 µm.

Germanium material is very suitable for designing lens since its refractive index with the ability to support impossible specifications to be created. Common applications of germanium lens include thermal imaging where the Germanium material can be used as a front optic while its index of refraction helps the lens to support wide-angle lenses.

Germanium lens are best in mid-infrared applications. They work very well in harsh environments . Shanghai optics offers the most known sizes having Anti-Reflection Coatings. The lens is likely to be affected by thermal runaway in that, when the temperature goes high the transmission goes down.

Specifications 

The Germanium lens are specified to be used at temperatures not exceeding 100 degrees Celsius. 5.33 g/Cm3, which is the Germanium’s highest density is put into consideration when making designs for weight-sensitive systems. Germanium lens are very good in IR applications requiring rugged optics.

This is attributed by the Knoop Hardness which is 780. In summary, Germanium lens have high Index of Refraction, minimal Chromatic Aberration due to low dispersion, ideal for Rugged IR applications as well as having popular sizes containing AR coating from 3-12 µm.

GERMANIUM CUSTOM SPECIFICATIONS 

Germanium lens can have various manufacturing limits which include; Anti-reflection coating of 3-12 µm, clear aperture having more than 85% of central dimension, surface figure of a quarter length each 633 nm, surface quality after coating of 20-10, Focal length of positive or negative one percent and lens of diameter 5 mm-350 mm. Additionally, Germanium lens can be manufactured containing different shapes like spherical plano-concave, P-Convex, Concave-Convex and Aspheric.

TESTING 

Germanium lens are tested with Zygo interferometer and spectrophotometer. This is the standard testing items which ensures the lens is of high quality.

Professional Fields that Require the use of a Germanium Lens


When it comes to optical lenses, most people are aware of the lenses used to correct a person's vision and those used in cameras. There are actually a large number of devices that require the use of precision lenses. Even the lenses found in cameras need to be manufactured to exact specifications in order to work properly.

A germanium lens is made using a material that allows for the passing of infrared light rays. Since most lenses have a silica base, these light rays are not able to pass. This means any type of device used for thermal imaging needs to be made with a germanium lens.

Quality Lens Manufacturers 

Thermal imaging is widely used in the medical profession. For this reason it is extremely important for the manufacturers of devices using germanium lenses to use a superior lens manufacturing company. The cameras designed to detect the heat or radiation emanating from a specific source, need to have lenses built that conform to the range of the space they will be able to detect the infrared rays. They also need to fit whatever type of mount or aperture they will be placed in.

Custom Designed Optics 

In addition to being widely used in the field of medicine, a germanium lens could also used for scientific research and is commonly found in cameras created for security systems. The military also uses infrared technology. Many of the devices found in these fields are created on an as needed basis, which means the lenses they use might have to be custom designed.

A lens manufacturing company such as Shanghai Optics, could offer these lenses as factory standards or custom creations. Some of the standard shapes for these lenses include variations of both concave and convex surfaces. They are also available with an anti-reflection coating.
