Ball Lens Unit
Lens components for cost-effective modules
The Ball Lens Unit consists of an ultra-high precision ball lens (microball) or microdrum, sealed directly into a module holder or receptacle using low-melting-point glass. This sealing method enhances reliability, reduces the number of components in the optical system assembly, and simplifies the overall process.
