N-BK7 Diameter 45 Machined Meniscus Lens 588nm Anti Reflection
N-BK7 Diameter 45 Machined Meniscus Lens
The shape of the lens can be changed by cutting to effectively save space. For example, the meniscus lens processed by us can effectively reduce the lens area through the edge grinding process, and our edge collapse can also be effectively controlled during cutting.
The machined meniscus can effectively improve its transmittance and reduce laser damage by coating.
