Product Family Description

  • Up To λ/250 Retardance Tolerances Out to 30° AOI
  • Near Zero-Order Laminated Polymer Construction
  • Ideal for Applications with Wide Acceptance Angles

Wide Angle Waveplates are designed to accept a large range of input angles, up to 30° AOI, with minimal retardance shift at non-zero angles of incidence. These waveplates are available with visible or NIR designed wavelengths of 532, 633, 1064 or 1550nm and with λ/2 or λ/4 retardance values. Featuring ≤λ/250 quarter-wave and ≤λ/100 half-wave retardance accuracies at the center, these waveplates are ideal for applications that require low sensitivity to AOI. Wide Field Waveplates are mounted and constructed with birefringent polymer on a N-BK7 substrate and coated with BBAR coatings.

Note: The fast axis is marked with a line.
