Our spherical plano-concave germanium lenses are generally used to diverge a beam from a collimated gentle supply, or to improve the focal size of an optical procedure.
Something over a hundredºC isn't advised. By the time it reaches 200ºC it is sort of opaque in any respect wavelengths. If you need a high temperature window, you’re much better suited to stay with a material like MgF2, YAG or our outdated Pal sapphire.
Ahead your materials requirements and We are going to answer by using a quotation. For some other inquiries or questions you should Get in touch with our proficient product sales team.
Thickness of Germanium window demanded to withstand tension differential at opposite sides can be calculated by the following equation:
You may electronic mail the internet site operator to let them know you have been blocked. Be sure to consist of That which you were being carrying out when this site arrived up and the Cloudflare Ray ID identified at the bottom of this webpage.
Both equally monocrystalline and polycrystalline Ge may be utilized for producing of optical factors. We create Germanium lenses and windows for infrared thermal imaging apps and pyrometry (see our webpage Germanium Home windows and lenses for thermography).
The quantity of holes present can be lessened by raising the amount of electrons from the addition of team V atoms (donors) for the Ge. This lowers resistivity. Excessive addition of donors brings about extreme electron focus and improved absorption.
We acquire and manufacture optical parts in the highest high-quality you can use in a number of fields of application, from laser product processing to biotechnology, health care engineering, protection and safety and the semiconductor current market.
A large-angle lens expands your thermal camera lens’ area of check out. If you need to see additional of what’s encompassing an asset, or are Doing work in a good Area, They're mission crucial to get the shot.
These significant-top quality cylinder optics are perfect for use in laser scanning, laser projection, beam homogenization and PCB fabrication. They're also a wonderful Resolution in fault analysis.
Developing a solitary crystal of germanium would be the starting point for producing substantial-high quality factors. The crystal framework and defect density can substantially impact its optical and electrical Attributes.
Content Variety: Higher-quality germanium substrate is important for making large-overall performance lenses, as any defects or impurities in the germanium crystals could impression the optical Qualities of the completed lens. Rely on Lattice to offer higher-quality customized-grown germanium to make sure high-quality lenses.
Optical Home windows : main utilization of germanium with Superb transmission in the IR and no transmission while in the obvious. Frequently, germanium windows are strengthened with DLC coating more info on a single face.
