Germanium Optics Handling and Cleaning Guidelines

Germanium optics require special handling and cleaning procedures. Always wear gloves during handling to prevent contamination, and wash hands afterward. Avoid contact between Germanium dust and the eyes, skin, or clothing. When not in use, store optics sealed and covered at temperatures between 20°C and 25°C. Do not expose them to temperatures exceeding 100°C when in use.

Handling Guidelines

Always wear gloves to prevent damage from skin oils.
If Germanium dust is present, take the following precautions:
- Wear safety glasses to protect eyes.
- Use a dust mask or face mask to avoid inhalation.
- Wear gloves to prevent skin contact.
Maintain storage temperature between 20°C and 25°C with humidity below 30%.
Wrap Germanium optics in a lens cloth or pouch and seal in a container when not in use.
Germanium is brittle and heavy — always place it on soft surfaces and avoid dropping it.
