Germaniumlens for thermal camera

Germanium or Ge has high transmission in the range of 2-16μm and is best used in mid-IR and long wave IR applications. Due to its low dispersion, it is a common choice for use in low power CO2 laser applications. Germanium also is opaque throughout the entire visible spectrum, making it ideal for applications where only IR transmission is desired.

UV formulations are liquid monomers and oligomers mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the formulation - inks, coatings or adhesives instantly “harden” or cure, ready for the next processing step.

Optical windows come in many shapes and sizes but a major factor is their material. The types of materials that an optical window is constructed from dictate the wavelengths (measured in nm) that they can view. In IR It is extremely important that selecting the right material is done to avoid many a headache and a waste of money and time.

Ultraviolet curing (commonly known as UV curing) is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” inks, coatings or adhesives.

UV curable chemistries must be cured completely, consistently and efficiently. This yields improved surface properties, aesthetic appeal, durability and function to components and products.

In various fields, optical windows serve many purposes. They act as protective barriers, shielding sensitive optical components from environmental factors such as dust, moisture, and contaminants. Additionally, they enable the transmission of light while minimizing distortion, reflection, and absorption, thus maintaining the integrity of the optical system.

Optical windows are employed in a wide range of applications, including scientific research, industrial manufacturing, aerospace, defense, and telecommunications. They are utilized in optical instruments like cameras, microscopes, telescopes, lasers, and sensors. By providing a stable optical interface, optical windows facilitate accurate measurements, imaging, and analysis of light, enabling advancements in numerous fields.

UV curable inks and coatings were first used as a better alternative to solvent-based products. Conventional heat- and air-drying works by solvent evaporation which shrinks the initial coating application by more than 50% and creates environmental pollutants.

Firebird provides these in several uncoated stock configurations in circular and rectangular shapes but can provide them customized and coated to your specifications.

Optical windows are transparent components made of materials like glass or crystal that are used to protect and control the flow of light in optical systems. IR windows and optics for use in FTIR Spectroscopy and CO2 lasers. This includes discs, rectangular plates and various other geometries.
