The LuphoScan 260/420 HD platform ushers in a new era of high precision metrology of optical surfaces. The new generation devices provide for the first time an absolute measurement accuracy of better than ±50 nm (3σ) up to 90° object slope. This comes along with ultra-high reproducibility of measurement results and a low noise floor.
The new instrument is ideal for applications where the highest accuracy is required and essential to the manufacturing process. This is most beneficial for surfaces with steep slopes, with varying pitch directions, and small surfaces, such as moulds for smartphone lenses.
