A Φ14 mm germanium blank cut on a conventional coring machine leaves a 5–10 mm kerf ring — that’s often more material wasted than the lens itself weighs.

Getting from a raw germanium ingot to a finished IR lens takes eight distinct manufacturing steps — and every one of them has a way to go wrong.

Choosing ZnSe lens production equipment is a full-line decision, not a single-machine decision. A CVD ZnSe boule enters the factory as an expensive, soft, selenium-bearing block; it leaves

CVD ZnSe blank cutting is the first yield-critical machining step in zinc selenide optics production. Before a CO2 laser lens can be ground, polished, coated, and inspected, the

Cleartran ZnS is a denser, tougher grade of zinc sulfide that requires more disciplined cutting control than standard CVD ZnS. Cut it with standard parameters and you get

Multispectral zinc sulfide processing behaves differently from standard ZnS processing in three specific ways: the grain structure that emerges after hot isostatic pressing tolerates less cutting force, the

Automotive thermal imaging systems require IR lens blanks cut to tighter dimensional tolerances than standard industrial optics — because a lens that passes incoming inspection can still fail

A 200 mm germanium ingot costs $6,000–$10,000 at current spot prices. Traditional core-drilling wastes 5–10 mm of material per blank cut; diamond wire saw cutting reduces that kerf

Every CO₂ laser cutting head contains a set of zinc selenide optics that the laser beam passes through before hitting the workpiece. Those lenses, windows, and output couplers
