Advanced digital microscopy for fast, accurate imaging and measurement. 

Evident Olympus LEXT OLS5500 

3D optical profilometers use noncontact measurement to capture high-precision surface data, making them ideal for delicate or complex parts in materials science, R&D, and manufacturing QA/QC. Evident 3D optical profilometers set a new standard in precision surface measurement, providing measurement confidence with precise surface detail, traceable accuracy, and smart automation. 

Uniting laser scanning microscopy (LSM), white light interferometry (WLI), and focus variation micro- scopy (FVM), the award-winning 3D optical profilometers offer true-to-form surface details across complex geometries. Identify subtle features and surface variations with unparalleled clarity—use LSM, WLI, and FVM to detect defects, confirm designs, and make confident decisions that help improve product quality and yield. 

Laser confocal optics acquire LSM images using a 405 nm laser diode light source and a high-sensitivity photomultiplier. In WLI, height information is obtained from interference fringes generated when light from a white light source is split by a beam splitter within the objective lens and refle cted from both the sample surface and a reference surface. FVM determines height information by identifying the Z-position at which the image contrast reaches its maximum.
