제품군의 상세 설명

이미징 용도에 안성맞춤
구면 및 코마 수차 등의 광학 수차 최소화
UV Fused Silica DCX Lenses 이용 가능
Anti-Reflection 코팅 옵션: MgF₂, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, YAG-BBAR

TECHSPEC® Uncoated Double-Convex (DCX) Lenses는 bi-convex lenses로도 알려진 제품으로서 양면에 동일한 반경을 가진 2개의 대칭형 볼록 렌즈로 구성됩니다. 이와 같은 렌즈는 일반적으로 0.2에서 5 사이의 conjugate ratio(피사체 거리와 이미지 거리 사이의 비율)를 갖는 finite imaging 용도에 권장됩니다. Conjugate ratio가 1이 될 때, 대칭형 렌즈 디자인이 형성되어 구면 수차, 색 수차, 코마 수차, 왜곡 등과 같은 각종 광학 수차를 최소화하거나 제거할 수 있습니다. TECHSPEC Uncoated Double-Convex Lenses는 가시광선 및 NIR 스펙트럼을 위해 다양한 기판 및 코팅 옵션을 선택할 수 있습니다.
