Precision-Optical Engineering (P-OE) has published the latest in its series of technical datasheets on diamond turning in the technical library section of its website
The new data sheet, DM006, is entitled Measuring Diamond Turned Aspheric and Diffractive Surfaces.
The measurement of diamond turned aspheric and diffractive surfaces requires a high degree of accuracy.
Diamond turned surfaces are typically measured for surface roughness (Ra) in nanometres; form error (or PV) in microns and step height for diffractive surfaces in microns.
Surface measurement methods include contact and non-contact techniques and this data sheet looks at both measurement methods.
This is the sixth datasheet in the diamond turning category and the 17th in total, which also includes optical systems engineering and infrared interferometry.
