Radial Polarization Converters (S-Waveplates)
• Converts Linear Polarization to Radial or Azimuthal and Circular Polarization to an Optical
Vortex (Donut-Shaped Beam)
• High Damage Thresholds in the Nano- and Femtosecond Range
• Higher-Order Versions Can Generate Higher-Order Polarization Patterns and Optical Vortices
Radial Polarization Converters (S-Waveplates) are space-variant retarders designed to convert linear polarization
to radial or azimuthal polarization to reduce laser beam spot size. Alternatively, they can be used to convert
circularly polarized light to an optical vortex (donut-shaped beam). Radially polarized beams are highly
effi cient at micro-drilling high aspect-ratio features in metal, while vortex (donut-shaped) beams are ideal for
STED or two-photon excitation fl uorescence microscopy, laser micromachining, and optical tweezer applications
(multiple particle trapping). Higher Order Radial Polarization Converters (S-Waveplates) can generate
higher order polarization patterns, optical vortices with increased topological charge, or vector Bessel beams
when used in combination with axicons. These types of beams are used in micromachining applications, such
as microhole drilling of transparent materials.

Crystalline Quartz Polarization Rotators
• Rotates Polarization by a Fixed Angle Regardless of Incident Polarization Angle
• Convenient Replacement of Half-Waveplate for Narrow Waveband Lasers
• 1064 nm, 532 nm, and 355 nm Anti-Re ection Coatings Available in both 45° and 90° Rotation Angles
Crystalline Quartz Polarization Rotators rotate the polarization plane of an incident beam by a fi xed angle,
regardless of the rotator’s alignment relative to the beam’s polarization. Polarization rotators are a good
alternative to waveplates with regards to rotating polarization by a specifi c angle. They produce a rotation
in polarization caused by the optical activity naturally present in quartz crystals being independent of the
rotator’s orientation around the optical axis. The Crystalline Quartz Polarization Rotators only need to be
aligned perpendicular to the direction of propagation of light. Rotators with fi xed 45° or 90° rotation at
Nd:YAG wavelengths, mounted in a black anodized aluminum mount, are available.

Free-Space Optical Isolators
• Up to 67 dB Isolation for Ultimate Stability
• Up to 92% Transmission for Maximum Power
• 4,7 mm Input Aperture
Free-Space Optical Isolators incorporate a Faraday
Rotator and are specifi cally designed and manufactured
to provide superior performance with high isolation,
transmission, and power densities. Each option
eff ectively reduces feedback in the external cavity of
diode laser systems and blocks refl ections from freespace
fi ber coupling. Free-Space Optical Isolators increase
power stabilization in optical systems and also
eliminate feedback-induced damage to sensitive optical
components. These isolators enable state of the
art protection for the most stable lasers in the world
and are ideal for demanding laser applications.
Clear Aperture (mm): 4,7
Damage Threshold, By Design: 40 W, 4 kW/cm2 @ DWL
Operating Temperature (°C): +15 to +40
