Fused quartz Ball lens
PRODUCT CATEGORIES
- Ball lens is used to improve the signal coupling between optical fiber, transmitter and detector and improve the signal quality. It can also be used in endoscopy, bar code scanning, pre-processing materials of aspheric lens, sensors, etc. The rear focal length of the spherical lens is short, which can greatly reduce the distance from the spherical lens to the optical fiber.
