Introduction In the specialized field of astronomical optics, manufacturing large-diameter lenses for telescopes demands unparalleled precision to avoid defects like edge chipping, distortion, and surface irregularities. This case study revolves around a customer’s ambitious request: a custom diamond wire loop cutting machine capable of handling 3-meter diameter optical glass blanks for telescope lenses. The challenges […]

Introduction In the demanding world of infrared (IR) optics, cutting germanium—a brittle semiconductor material prized for its high refractive index and IR transparency—presents significant challenges, including edge chipping and achieving precise rounded (R) corners. This case study highlights a customer’s requirement to cut a complex shape from germanium for AR (Augmented Reality) lens applications, as

Introduction In the realm of optical manufacturing, cutting irregular shapes poses unique challenges, requiring precision to maintain optical integrity while achieving complex geometries. This case study arises from a customer’s need to cut two optical lenses from a raw material into irregular shapes, suitable for advanced optical applications such as custom prisms or aspherical elements.
