Drum lens
PRODUCT CATEGORIES
- Drum lens is a lens whose two ends are spherical and provide positioning surface along the optical axis direction. It is formed by grinding the outer circle on the basis of the spherical lens to facilitate card loading. It is more suitable for the propagation of light in optical communication.
- We provide uncoated drum lenses based on K9 optical glass and UV fused quartz. Fused quartz is suitable for UV applications.
