Qualifying Optical Tooling
Single-point diamond turning is heavily utilized when manufacturing contact and intraocular lenses (IOL) either directly or in the successive processes of producing tools, molds, and lenses. This application note describes the autoROC motorized instrument for measurement of spherical, toric, and aspheric surfaces.
This is a comparison laser diode analysis between conventional camera-based method (ISO 11146) and an Optocraft SHSLab Shack-Hartmann wavefront sensor. This application note describes the beam parameter calculations for beam diameter and M-squared beam propagation factor.
Optical vortex beams are light waves with an orbital angular momentum (OAM). This application notes describes the measurement of several spiral phase plates with topographical charge of one, two, and three respectively. Standard wavefront sensors are available for the UV, visible-NIR and infrared spectrum.
