제품설명

회절 한계 성능
다양한 코팅 옵션
Prescription 데이터 전체 이용 가능
저마늄 수급에 차질이 생겨 저마늄 제품의 경우 납기가 지연되거나 가격이 변동될 수 있으니 자세한 내용은 고객 서비스 팀에 문의하시기 바랍니다

TECHSPEC® Germanium Infrared (IR) Aspheric Lenses는 중파 및 장파 적외선 범위 전체에서 회절 한계 포커싱 성능을 제공합니다. Quantum cascade laser와 같은 단색 광원에 적합한 이 렌즈는 standard plano-convex lens를 대체할 수 있는 고성능 제품입니다.

각각의 aspheric lens는 비코팅 상태로 공급되거나 BBAR 코팅 옵션을 적용할 수 있습니다. 비코팅 게르마늄은 투과율이 50% 미만이기 때문에 코팅 처리를 하지 않은 렌즈의 경우 맞춤형 무반사(AR) 코팅을 고려할 수 있습니다. BBAR 코팅 처리된 렌즈는 투과율이 95%가 넘기 때문에 다양한 OEM 용도에 결합해서 사용하기 적합합니다. 맞춤 주문 설계 및 코팅 옵션은 당사 영업부로 문의 바랍니다.

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.
