Aspheric lenses and aberration free lens doublets are high performance alternatives to our short focal length ZLF series meniscus lenses. Both options give diffraction limited performance by correcting the spherical aberration that is present in a “best form” meniscus lens.
The aspheric surface is most effective in lenses of short focal length. See below for a selection of the aspheric lenses we can offer.
The alternative solution to eliminating spherical aberrations is through our TF series of aberration corrected double element lenses.

Beam Expanders for 1μm lasers
ULO Optics are excited to introduce our new range of beamexpanders. Designed for low power (500w) lasers such as Nd:YAG and Yb doped fibre lasers operating near the 1μm wavelength. The beamexpanders are of Galillean design and use Multi-spectral Zinc Sulphide for the optics which has an absorption at 1μm of 0.0005cm−1 (Similar to ZnSe at 10.6μm).
Diversification into 1 micron optics
ULO Collaborate on the LaserSnake2 project, developing laser cutting optics for safe, remote cutting in air and in water, focused on nuclear decommissioning.
ULO Optics develops CO2 Brewster plate beamcombiner
In our new beamcombiner – C-BC-2, pairs of enhanced Brewster Windows are used to attenuate a linearly polarised CO2 laser beam. The Brewster plate acts like a polarising beamsplitter. The difference in reflectance also allows two perpendicular polarised beams to be combined into a single beam.
