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.

Optogama offers a wide range of precision-engineered waveplates, including crystalline quartz, achromatic (broadband), and mid-infrared options to meet diverse application requirements.

Crystalline quartz zero-order waveplates—available as air-spaced half-wave and quarter-wave designs—are optimized for specific wavelengths within the 257–1550 nm range. The zero-order configuration ensures reduced sensitivity to temperature and wavelength fluctuations compared to multiple-order alternatives.

Achromatic (broadband) waveplates are designed for stable performance across wider spectral ranges, covering bands from 460 nm to 1700 nm, and are available in both half-wave and quarter-wave versions.

For mid-infrared applications, Optogama supplies monolithic, zero-order waveplates covering 2800–10600 nm (MWIR and LWIR). These are available with standard or custom retardance values and are well-suited for demanding IR systems.

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.

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.

Lasers, Optics, Electronics. Made in Germany.

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.

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.
