Coupling laser focusing mirror Dia:30mm FL=40mm Quartz material for laser machine

Laser cutting and engraving machines use a laser beam with a diameter around one-quarter of an inch (240 thousandths). In order to achieve high-quality engraving and precise cutting, the laser beam uses a system of mirrors and focus lens that redirect the laser.

Laser systems use plano-convex lenses to focus laser light. Laser light enters a convex lens and begins to converge to a focal point, upon crossing the focal point, the light then diverges out again.

This focus converts the laser beam into a very small and precise spot with extremely accurate results for a wide variety of applications. As the laser beam leaves the focus lens, being positioned in the ideal focal distance, it starts to make the cut or engrave.

Description of laser focusing lens:

Focusing lens is one of the important parts of laser marking machine, which aims to focus the laser on the whole marking plane.

The focusing lens is the last optical device in the laser path. The anti-reflective coating on the focusing lens surface is made of Quartz JGS1, and the focusing lens is usually a plano-convex lens or a curved lunar surface lens. To ensure efficient laser operation, the choice of lens is critical. The type used for each machine is usually indicated in the machine manual. It could bear the 3000W power

Specification of focusing lens:

Advantages of laser focusing lens:

1.High transmittance, fast cutting speed

The transmittance of laser focusing lens could reach to 99.8%,Effectively enhance cutting speed,There are Anti-reflective coatings with high damage threshold on both sides of the focus lens,which can effectively reduce the loss caused by reflection.

2.Double sides coating, Strong durability

Long service life, more durable, double-sided coating can effectively protect the focus lens from splashes and other hazards, thus increasing the service life.

3.Excellent optical properties and good stability

The focusing lens has good thermal stability, high temperature resistance and excellent laser resistance.

What is the focus lens?

Laser Lenses are used to focus collimated light from laser beams in a variety of laser applications. Laser Lenses include a range of lens types including PCX Lenses, Aspheric Lenses, Cylinder Lenses, or Laser Generator Lenses. Laser Lenses are designed to focus light in several different ways depending on the lens type, such as focusing down to a point, a line, or a ring. Many different lens types are available in a range of wavelengths.
