Optical system

This is a focusing unit of transmitted beam by fiber. Transmitted beam by fiber have a dispersion and to focus this beam is more difficult than pallael light. This unit can focus transmitted beam(for N.A=0.2, 0.16). This unit is composed of two parts. One is collimate lens part, and other is focus lens part.

• This unit is of use to focus constant magnification despite core diameter of fiber.
• This unit is of use to focus constant magnification despite core diameter of fiber.
• To change focus lens part, diameter of beam spot is change.
• This lenses were coated YAG AR.
• Focus lens part can be used for pallael light.

• We can custemize and remodel laser head for water-cooled system or air-cooled system,
• We have an experience to make laser head for homogenize beam unit, focus lens unit etc.

• When high power laser beam radiate mirror in continuity, thermal energy occur in the area irradiated. As a result, digradation of laser mode occur by thermal effect increased. In some cases, mirror is damaged by laser. Water-cooled folder solve thermal problem by cooling efficiently.

• Usually, transverse mode of laser beam have nearly a gaussian profile. If gaussian beam used for laser machining, processed surface is inequable form between center and edge. Beam homogenizer transfer laser beam and make a top-hat beam. Top-hat beam have a homogeneous radiation. homogenizer is used for beam sharping device too(e.g. square beam, and line beam).
• We can design for many homogenizer which are fly-eye lens unit, kaleidoscope(rod integrator), trapezoidal prism, DOE etc.
• Every homogenizer have transmission loss is average 3-20%.
• We can supply only homogenizer or homogenizer unit contained focus lenses and laser head.
