Also they are typically used in aerospace industries such as in satellite imagery sensors and in life and medical sciences for healthcare diagnostics.
Our spherical plano-concave germanium lenses are largely accustomed to diverge a beam from a collimated mild source, or to increase the focal size of an optical procedure.
We can manufacture aspheres in rotationally symmetrical, ellipsoid and off-axis styles to fulfill your precise demands. In this process, we're one of several number of organizations around the world to utilize a variety of optical resources, for example glass, glass ceramics, quartz glass, crystals like calcium fluoride, magnesium fluoride, germanium and silicon and metals. The antireflection coatings around the aspherical components include a spectral range from DUV to IR.
Send us your specific requirements, and our technical revenue representatives will review what is necessary to deliver Prepared-to-use elements inside your lead time.

Welcome to UQG Optics! It looks like that you are viewing from your US. Choose your desired currency beneath to determine suitable pricing. Make contact with us for additional help or to discuss specific requirements.
It’s also a good selection for those who’re scanning overhead vents or duct perform, superior-power transmission towers which are a length get more info away. The telephoto lens permits you to do the job safely and securely from the ground.
Germanium lenses are optical lenses made of polished germanium. Germanium Optics are rugged and proof against corrosion, and are perfect for harsh environments and applications in which You can find consistent exposure to The weather.
When this material is protected by a appropriately engineered anti-reflective coating, it will become an very successful product to transmit Electricity into a thermal digicam detector and make higher-high-quality thermal illustrations or photos. The coating can be designed with ruggedness in mind which enhances scratch resistance.
There are several specialized troubles in producing germanium factors for infrared optical techniques, for instance maintaining higher optical good quality over a wide range of temperatures, minimizing undesirable radial resistivity gradients, and decreasing the absorption of infrared radiation.
We may make tailor made specs to non-conventional sizes of optical crystals. Novotech can offer the material fabricated to most customer’s technical specs. With an intensive fabrication potential, we could generate normal generated lens blanks inside of a one-to two-week time frame.
The sharp transmission Slice-off ahead of twoµm also permits germanium for use as a protracted pass filter, only transmitting wavelengths in excessive of 2µm and totally blocking every little thing prior to it.
As an alternative to needing many different cameras to accomplish these responsibilities, you can save a lot of cash with “clever” include-on lenses that may be utilized between many suitable cameras without having Exclusive recalibration for each digicam and be capable to rapidly swap out lenses on The task.
Uncooked germanium material is quite tricky but can nevertheless correctly be machined and polished into optical elements:
