Plasma-enhanced figuring technology for ultra-precision optics
The SPP-200 introduces a proprietary finishing technology, engineered to achieve the highest levels of uniformity and ultra-precise surface demands in optical manufacturing. At its core is a cutting-edge low-temperature plasma jet operating under atmospheric pressure. This non-contact technology allows chemical material removal without applying mechanical stress to the lens. The result is an unprecedented level of shape accuracy and process reliability across all optical geometries.
- Superior form accuracy: Enables users to execute final corrections for ultra-precision components that require best form accuracy.
- Deterministic material removal rate via controlled dwell time, reducing iterative processing steps.
- Fine error correction: Enables small spot correction of mid-spatial frequency errors, processing an area of just 1–2 mm.
- No mechanical stress on the lens: Contact-free processing, preventing subsurface damage and micro-cracks
- Geometric freedom: Processes all optical surface shapes with virtually no geometric constraints, eliminating the need for complex tooling.
- Economical operation thanks to low consumables consumption and cost
- Clean and dry process that leaves behind no polishing residue and generates minimal waste
- Seamless integration with Satisloh ProACT—the powerful yet easy-to-use Software Suite—unlocks the SPP-200's full potential for calculation, adjustment, and fine correction tasks.
- Effortless setup: Easy and convenient job setup via Satisloh’s guided user interface, BaSyS.
- Non-contact measurement and calibration tools as part of the machine and software equipment.
- Full circle manufacturing: Satisloh’s Hydra-sonic ultrasonic cleaning systems perfectly complement the manufacturing process, for optics clean and ready to coat
