Custom Optical Lenses
1064nm Fused Silica Laser Lenses
CLZ Precision Optics provides 1064nm laser lenses, which absorbs less laser energy and greatly improves the performance of laser. Because optical lenses are used in the the special environment of laser, when producing laser lenses, we select optical materials and control the tolerance range strictly according to custom dimensions. We use sophisticated instruments and rich experience to ensure the quality of optical lenses. Through the production process, optical lenses are minimized the wavefront distortion and reduced effects of aberration and scattering.
As a manufacturer of optical components, the high-performance coating of custom optical lenses provided by our company maximizes the transmittance. The laser lenses have high laser damage threshold, resist thermal damages, withstand high current, and are suitable for high power and high energy Laser.
Plano-convex lenses focus parallel light to a single point, which is always used to focus, collect and collimate rays.
The surfaces of the biconvex lenses are all convex spherical surfaces with equal radius of curvature. The spherical aberration of biconvex lenses is minimized. The coma and distortion of biconvex lenses are eliminated.

The functions of optical lenses in the laser:
There are three functions of optical lenses in the laser, that is focusing, coupling and collimation.
1. Focusing lens: Focusing lens is widely used in laser processing, such as laser marking machine, laser cutting machine, laser welding machine, etc.
2. Coupling lens: When the fiber laser transmits laser light, the laser beam needs to be collimated through the lens and focused into the fiber.
3. Collimating lens: In the beam delivery system, it maintains the collimation of the beam between the laser resonator cavity and the focusing optical elements. It is widely used in laser machines, such as laser marking machines, optical fiber cutting machines, and handheld welding machines.
