Practical guides to optical cutting, grinding, polishing and inspection—from material selection to process troubleshooting.

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

Can high precision cutting machines be accurate above cutting speed? Are things continually breaking? Users of high-precision cutting machines in hectic workplaces have requested this. Faster running is

The wire loop can snap during cutting. This is a serious setback. It can be a safety issue too. A high tension wire has a lot of energy

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

An expensive slab can be rendered scrap by an incorrect setting. It only takes seconds. If you’ve ever watched a clean cut turn into a jagged edge then

Look up a CNC glass cutting machine and prices can skyrocket by tens of thousands of dollars. Two machines can look almost identical on paper. So what’s all

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
