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

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.
