Optical Components

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

Entire surface produced with Ra < 0.01 µm on the HSC machine

Surface quality after milling

with a 4 mm ball nose cutter, surface quality Ra < 10 nm, machining with small step over from tool path to tool path
