详细介绍

Features

  • High Energy Air Spaced Design
  • Quarter and Half Waveplates Available
  • Operates as a Quarter Wave for One Wavelength and a Half Wave for Second Wavelength

Thorlabs dual wavelength, multi order waveplates are made from high quality crystalline quartz and are available at quarter-wave or half-wave retardance. The waveplates are designed to be used in dual wavelength setups (1064nm and 532nm) and operate as a quarter wave waveplate in one wavelength and as a half wave waveplate in the second wavelength. Two models are available: λ/[email protected]; λ/[email protected] and a λ/[email protected]; λ/[email protected]

The term "multi-order" refers to the fact that the retardance of a light path will undergo a certain number of full wavelength shifts (also referred to as the order, or m) in addition to the fractional design retardance. Compared to their zero-order counterparts, the retardance of multicolor waveplates is more sensitive to wavelength and temperature changes, however, they are less expensive and find use in many applications where the increased sensitivities is not an issue.

Our waveplates are mounted in a 1" housing with the principal plane of the waveplate clearly marked with a straight line on the housing's front panel. Available as either λ/2, for rotating the polarization or λ/4, for converting linearly polarized light into circular polarization and vice versa. For further information on using and selecting a waveplate please visit our Selection Guide tab. In addition to the multi-order Waveplates Thorlabs also offers Achromatic Waveplates, Telecom Zero Order Waveplates, Zero Order Waveplates, and a complete line of Polarization Optics.
