Focusing Module optimized for Beam Shapers 





 

























For applications requiring an aberration-free image in the
focal plane, with high

precision, HOLO
/OR developed a new optimized focusing module to be used with
our Beam Shapers.

A standard focusing lens (or objective) is normally optimized for
focusing a Gaussian beam, thus, its use with Beam-Shapers often causes
aberrations of the Top-Hat image and requires special design of a focusing
lens or module. These aberrations will normally occur at small focal
lengths, short wavelength, large input beam and large image. To solve
this problem, HOLO
/OR designed a focusing module (with focal length 50
[mm]) adapted to our Beam Shaper working at 355 [nm]. We
also 
offer customization for other wavelengths and focal
length.
