The core measurement technology is based on focused laser reflection (see LAS Technology). A single-mode optical fiber couples the external Laser Generation Module (LGM) to the on-tool vertically-mounted Optical Module (OM) which houses the focusing optics and large-format array camera(s). Software control of the LGM permits fast switching of wavelengths and optimization of the beam power, resulting in superior imaging of the reflected beam with sub-micron measurement precision. The design of the LGM permits up to two of three visible wavelengths (blue, green & red). 

The user friendly CalcuLens™ Assembly software is standard to all LAS™ models and enables computer automated measurement of the alignment errors of a single lens for rapid bottom-up assembly. Extending the measurement to multi-element lens assemblies requires the optional CalcuLens™ Inspection software thereby adding powerful inspection capability for the quality assurance of finished lens assemblies. The recent addition of CalcuSurf-1D™ USB lever probe and profiling software to the LAS™ family of products significantly aids the ease and precision of initial setup, resulting in improved utilization during frequent lens assembly changes.
