The retardation optics of type 5WP-4-660Z-L is a quarter-wave plate that transforms linearly polarized radiation with 660 nm into circularly polarized radiation.
- Attachment optics with system mount Ø 8 mm for fiber collimators type 60FC with outer diameter Ø 12 mm
- Zero-order quarter-wave retardation optics with an 1.5° inclined mounting in oder to avoid direct back-reflections
- Center wavelength: 660 nm
- Free rotation for best adjustment with positional locking using radially arranged screws.
- Long-form housing with system mount Ø 8 mm for adding additional attachment optics
- Adjustable using Schäfter+Kirchhoff Polarization Analyzer series SK010PA.
- For collimating focal lengths f > 25 mm Schäfter+Kirchhoff offers fiber collimators of type 60FC-Q with integrated retardation optics.
