Glass prisms

Machin­ing of opti­cal glass prisms with extreme angu­lar pre­ci­sion below 2 arc sec­onds, also for large prisms. Rough­ing and fin­ish­ing in one set-up on 5‑axis and respec­tive­ly 3‑axis machine

Since begin­ning of 2012 due to new devel­op­ments in dri­ve and spin­dle tech­nol­o­gy extreme­ly high sur­face qual­i­ties are achiev­able, which are com­pa­ra­ble to such pro­duced on ultra-pre­ci­sion machine tools (UP machines).

Reflectors

Pro­duced with air bear­ing spin­dle on the machine

• Pre­ci­sion +/- 1 µm
• Sur­face qual­i­ty Ra = 0.005 µm
