Focus Lenses

The condenser lens is a crucial optical component, and its core value lies in the precise manipulation of light. The main wavelengths include 10.6 μm，1064 nm，523nm.The core function of a focusing lens is to converge divergent light into a single point, forming a high-energy-density spot. Its principle is based on the curvature design of optical lenses, which adjusts the light path to achieve focusing. Key parameters include focal length, scanning range, and spot diameter, all of which directly impact the focusing performance.
