LBTEK Super Achromatic Quarter-Wave Plate (SAQWP) is composed of three quartz wave plates and three MgF2 wave plates. The retardation and angles of these six plates are strictly designed and controlled to achieve achromatic performance within the intended wavelength range. The phase retardation of the LBTEK Super Achromatic Quarter-Wave Plate is π/2 within the design wavelength range, and it is commonly used to convert linearly polarized light into circularly polarized light. Compared to traditional single-wavelength wave plates, the super achromatic wave plate is not limited to a specific working wavelength and can achieve polarization state conversion for any wavelength within the design range. Compared to traditional achromatic wave plates, the super achromatic wave plate offers a broader achromatic wavelength range, better meeting customer requirements. Standard super achromatic quarter-wave plates are available with design wavelength ranges of 325-1200 nm, 355-1200 nm, 600-2700 nm, and 600-2200 nm, with clear apertures of Ø10 mm, Ø21.5 mm, and Ø45 mm, corresponding to installation in standard SM05, SM1, and SM2 lens tubes. In addition to standard products, LBTEK also offers flexible customization of parameters and specifications. For specific customization requirements, please contact LBTEK Technical Support.

Super Achromatic Quarter Wave Plate, Clear Aperture Ø10 mm

Retardance: λ/4
Clear Aperture: Ø10 mm
Operating Wavelength: 325-1200 nm, 600-2700 nm

LBTEK's super achromatic quarter-wave plate with a clear aperture of Ø10 mm is composed of three quartz wave plates and three MgF2 wave plates bonded together. By controlling their relative angles, it achieves an ultra-broadband achromatic effect. Standard products are available with working wavelengths of 325-1200 nm and 600-2700 nm, both mounted in standard SM05 lens tubes. The surface is engraved with product model, retardation, design wavelength, and fast axis direction for easy identification and use.

Super Achromatic Quarter-Wave Plate, Clear Aperture Ø21.5 mm

Retardation: λ/4
Clear Aperture: Ø21.5 mm
Operating Wavelength: 325-1200 nm, 355-1200 nm, 600-2200 nm

LBTEK's super achromatic quarter-wave plate, with a clear aperture of Ø21.5 mm, is constructed by bonding three quartz wave plates and three MgF2 wave plates. By controlling their relative angles, it achieves an ultra-broadband achromatic effect. Standard products are available with working wavelengths of 325-1200 nm, 355-1200 nm, and 600-2200 nm, all mounted in standard SM1 lens tubes. The surface is engraved with product model, retardation, design wavelength, and fast axis direction for easy identification and use. The Ø21.5 mm super achromatic quarter-wave plate with a working wavelength of 325-1200 nm offers a broader bandwidth, making it more suitable for broadband applications with small spot sizes. The Ø21.5 mm super achromatic quarter-wave plate with a working wavelength of 355-1200 nm provides better wavefront quality, making it more suitable for applications with large spot sizes.
