Introducing the Achromatic Wave Plates, a precision optical component designed to meet the highest standards of performance and reliability. Crafted from high-quality birefringent crystals, these wave plates are engineered to provide exceptional phase retardation accuracy and minimal wavefront distortion. The meticulous construction ensures that each plate maintains a diameter tolerance of +0.0/-0.2mm, making them ideal for applications requiring precise optical alignment.

The Achromatic Wave Plates are available in both quarter-wave (λ/4) and half-wave (λ/2) standard types, catering to a wide range of optical requirements. They are designed to operate efficiently across multiple standard wavelength ranges, including 450-650nm, 550-750nm, 650-1100nm, and 900-2100nm. This versatility makes them suitable for various optical systems, ensuring optimal performance across different spectral regions.

With a phase delay precision of λ/100 and a parallelism of less than 10 arcseconds for the cemented type, these wave plates guarantee superior optical performance. The surface quality is maintained at a 40/20 scratch and dig level, ensuring minimal scattering and high optical clarity. The effective aperture exceeds 90% of the central area, maximizing the usable optical surface for enhanced efficiency.

While the standard wave plates are uncoated, anti-reflective (AR) coatings are available upon request to further enhance performance by reducing surface reflections. Additionally, custom sizes and wavelength specifications can be accommodated to meet specific application needs, providing flexibility and adaptability for specialized optical setups.
