关于我们

TOPAG Lasertechnik GmbH has been founded in 1993 and is established as major supplier for products in laser technology and laser optics. The product range covers pulsed Nd:YAG lasers for spectroscopy, ablation and marking as well as fast pico- and femtosecond lasers for micromachining. Tunable OPOs with nano- and picosecond pulse length provide wavelengths from deep UV up to IR with customized tuning. Further laser products are diode laser modules, supercontinuum light sources and fiber lasers, completed by analytical devices like autocorrelators and interferometers. Spectrometers for spectral analysis, wavemeters for laser monitoring and monochromators for wavelength separation are completing the spectral product range. TOPAG developed diffractive variable attenuators for high power lasers. Diffractive and refractive laser beam shaping optics, e.g. for TopHat generation and beam splitting are developed for use in laser micromachining and optical measuring technologies.



展示产品

TOPAG Lasertechnik GmbH developed diffractive and refractive laser beam shaping optics. TopHat beam shapers transform a Gaussian input beam into a homogeneous square, rectangular or circular spot shape in working plane. TopHat beam shapers increase the quality and speed of the ablation process. Beam splitters generate 1- or 2-dim. spot arrays. These spot arrays are for example used in optical metrology and for parallel processing. TOPAG also offers customized solutions in beam shaping and splitting. Further products are beam samplers for monitoring as well as diffractive variable laser beam attenuators for high power industrial lasers.

GTH – Gauss-to-Top Hat beam shaper

GTH – Gauss-to-Top Hat beam shaper

These types of beam shapers have a free form surface which redistributes a Gaussian input beam (TEM00) into a Top Hat profile. TOPAG offers three standard modules for square Top Hat shape. Typical Top Hat width are from 100µm up to 2mm using GTH-4-2.2 or GTH-3.6-1.75 or from 500µm up to few cm using GTH-5-250-4. GTH beam shapers operate within a wavelength range from VIS to NIR. Other Top Hat shapes (rectangular or circular) or sizes on request.

FBS – Gauss-to-Top Hat Focus Beam Shaper

FBS – Gauss-to-Top Hat Focus Beam Shaper

By introducing the FBS beam shaper in front of an existing focusing optic, a Gaussian input beam is transformed into a near diffraction limited homogeneous Top Hat profile in focal plane, typically with sizes of several micrometers. The achievable Top Hat size just depends on the used wavelength (lambda) and the numerical aperture (NA) of the focusing system and is approximately given by lambda/NA.

DBS – Diffractive beam splitter

DBS – Diffractive beam splitter

Beam splitters are diffractive optical elements for generation of linear or 2-dimensional spot arrays (n x m). They are suitable for parallel laser material processing, parallel laser scanning, laser perforation and optical measurement to increase throughput. Beam splitters can also be used in combination with beam shapers.

新闻和创新

Micro Lens Arrays 

TOPAG has developed a new range of customized lens arrays produced in molding technology. This allows to offer large quantities at attractive pricing.
Available lens arrays can be with pitch of less than one mm, total active area can be up to 1inch, acceptable wavelengths are from 400nm to NIR. Lens geometries can be rectangular or round, lenses can be cylindrical, spherical or aspherical, singel or double side surface structuring is available.
