Applications & Technical Guides

Optical coatings are used in industrial laser processing, machine vision, optical measurement, medical and life science instruments, and automotive optical sensing. Their functions include reducing unwanted reflections, controlling transmission, reflecting selected wavelengths, and filtering or separating spectral bands. The same clear-looking window can therefore serve very different purposes: transmitting a processing laser beam, protecting a …

Replacing a protective lens exposes an optical surface at the moment it needs careful handling. Dust from the workshop, fibers from wiping materials or a fingerprint introduced during installation can leave a replacement optic in a different condition from the one supplied. Clean handling for laser cutting head optics helps preserve that surface condition between …

A physical sample can be a useful starting point for a custom optical component inquiry when a complete drawing is unavailable. Manufacturing may be possible after the requirements and feasibility are confirmed. The sample alone does not guarantee that every original dimension, material, coating or optical requirement can be recovered. Likai Laser evaluates custom optical …
