Lenses with metal holders for fiber coupling/collimation

There are many kinds of lenses with metal holders. The lens and the metal bracket can be tightly combined by glass molding. With the help of the metal bracket, the lens can be easily fixed to the product by laser welding. . This design is widely used in optical communication and laser optical products.
