We offer a wide choice of zero-order, multiple-order and low-order waveplates made from crystalline quartz. Also, we have dual-wavelength waveplates for Ti:sapphire, Yb:KGW/KYW and Nd:YAG lasers, and achromatic waveplates for tunable lasers.

Optogama provides crystalline quartz waveplates, achromatic (broadband) waveplates, and mid-infrared waveplates:

• Mounted crystalline quartz zero-order compensated, air-spaced half-wave and quarter-wave retardance waveplates are designed for a particular wavelength in the range of 257 – 1550 nm. Zero-order design features lower temperature and wavelength dependence compared to low and multiple order waveplates.
• Mounted achromatic (broadband) half-wave and quarter-wave retardance waveplates are intended for several bands in the wavelength range of 460 nm – 1700 nm.
• Unique zero-order, monolithic design mid-infrared (MWIR and LWIR) waveplates for the spectral range of 2800 nm – 10600 nm are available with quarter-wave, half-wave or any other custom retardance.

Hangzhou shalom EO offers an extensive range of off-the-shelf and custom waveplates and retarders including zero-order waveplates, true zero-order waveplates, achromatic waveplates, super achromatic waveplates, dual wavelength zero-order waveplates, low-order waveplates. These waveplates composed of quartz or MgF₂ crystal plates enable unrestrained control of polarization states with the additional advantage of high damage threshold. While we also provide polymer true zero order waveplates that are less sensitive to the angles of incidence. The structures of the waveplates can be varied for different requirements, such air spaced, cemented, or optically contacted designs. Retardation values like quarter waveplates, half waveplates, λ/8, or other custom retardance are accessible. Different coatings, standard diameter 1/2”, 1” and 2” mounts, including manual rotation mounts are available.

Fresnel rhombs that create uniform λ/4 or λ/2 retardance over a wider range of wavelengths than possible with birefringent waveplates are also procurable.

ALPHALAS offers unique tunable and standard phase retardation plates (waveplates). A single UVIR type quarter-wave or half-wave plate can be adjusted to the desired phase retardation for an arbitrary wavelength from 150 nm (vacuum-UV) to 6500 nm (far infrared) and the FIR type waveplate from 1 μm to 21 μm. The bandwidth is up-to 200 nm. They replace hundreds of ordinary phase retardation plates required to cover these ultrawide spectral ranges. The tunable waveplates are by design zero-order and can be used for polarization control of broad-spectrum laser sources like femtosecond lasers and OPOs.

Conventional zero-order, low-order and high-order waveplates for all standard wavelengths as well as customized designs and Fresnel rhombs are also available.

Applications span from polarization measurement and control, polarimetry, laser research, spectroscopy up to nonlinear optics.

Avantier produces microwaveplates with extremely small dimensions, as small as 0.35 mm × 0.35 mm, with a tolerance of ±0.05 mm and a thickness of about 0.19 mm. For more information on our manufacturing limits or to request custom specifications, please contact us.

The Future Depends on Optics

Edmund Optics offers a variety of waveplates with crystalline or polymer materials, including multiple order, zero order, or achromatic waveplates. Polymer waveplates offer superior performance over a wider range of incidence angles. Multiple order waveplates are ideal for use with monochromatic light that deviates less than 1% of the waveplate’s design wavelength. Zero order retarders offer high performance over wider wavelength or temperature ranges. Achromatic waveplates offer the most constant performance over the widest wavelength or temperature ranges.

WOP offers polarization converters which are exceptional for their ultra-high damage threshold, suitable even for high-power lasers.

S-Waveplate converts linear polarization to radial or azimuthal polarization and circular polarization to an optical vortex.

Main features:

• converts linear polarization to radial or azimuthal polarization
• converts circular polarization to an optical vortex
• high 94% transmission at 1030 nm (no AR coating)
• stand-alone – no additional optical elements needed
• high damage threshold: 63,4 J/cm² at 1064 nm, 10 ns and 2,2 J/cm² at 1030 nm, 212 fs
• suitable for high LIDT applications and high-power lasers
• reliable and resistant surface – the structure is inside the bulk

Additional waveplate assortment:

• higher order S-Waveplate: converts linear polarization to higher-order polarization patterns

Bringing quality into focus

Knight Optical offers a range of stock and custom waveplates. Our stock catalogue consists of zero and low order quartz waveplates, achromatic waveplates, mica retarders, and plastic retarders. With our custom capabilities we are able to offer a wider variety including multiple order waveplates.

YOUR KEY to innovation and success

AURORA, by UltraFast Innovations (UFI®), is a phase retarder (quarter waveplate) with a four-mirror grazing incidence reflection geometry for the extreme ultraviolet (XUV). It covers the range from 10 to 35 eV or 40 to 85 eV photon energy and reaches >25% transmittivity around 66 eV. A clear aperture of 3 mm allows the low divergent XUV from a high-harmonic-generation HHG cell to pass through without clipping.

Your problem is our challenge – flexibility is our standard!

Artifex Engineering offers a wide range of custom waveplates for many applications. Waveplates, also known as retardation plates, are birefringent optical elements. Our portfolio covers achromatic, low order, zero and true zero order and MID-IR waveplates. Mounts are available for our waveplates on request. For example, we can provide true zero order plates mounted on an annular glass frame. In this manner, a robust optic is available with the full optical properties of a true zero order waveplate. In addition to single components, we will gladly provide functional subunits according to your needs. For example, we can supply isolators comprising a quarter-waveplate and polarizing beamsplitter cube mounted together in a single drop-in unit. Visit our product page for more information on each waveplate. We look forward to your inquiry.
