         New Products             Scan Lenses (f-theta Lenses) for YAG Lasers

 

Lenses used in combination with XY galvanometer scanner are called -theta lenses, plane field objectives or simple scan lenses. -theta lenses are used in various applications from industrial material processing, drilling, welding of synthetic material and cutting in addition to medical and biotechnology (confocal microscopy, ophthalmology) to science and research. The design and the quality of the optical components are playing a decisive role.

 

A standard lenses focus the laser beam on a spherical plain in contrast to an ideal flat or plane field. The use of -theta lenses provides a plane focusing surface and almost constant spot size over the entire XY image plane or scan field. The position of the spot on the image plane is directly proportional to the scan angle.

 

The scan length specifications in this catalogue are based on mirror spacings of typical scan heads. For other scan systems the parameter aperture stop defines the distance of the geometrical center between the mirrors to the mechanical edge of the lens housing.

 

Telecentric -theta lenses focus the laser beam so it is almost perpendicular (within 1 degree) to the work surface over the entire scan field. This ensures the spot is round even in the corners of the scan field and if holes or channels are machined, they are perpendicular to the work surface.

 

Color corrected -Theta lenses are designed to accommodate multiple wavelengths. Normally each wavelength would focus to a different point on the work surface. In a color corrected lens the focal point for each wavelength coincide. This is achieved by schlechtging an ideal combination of different glass types for the various lens elements in the lens. Color corrected -theta lens are primarily used for simultaneously viewing the work surface through the scan lens with a camera while laser processing. Another common application for color corrected scan lenses are for use in confocal scan microscopes which require a broad range of visible wavelengths.
