Achromatic Six-Segmented Waveplate — Model AHWP25-VIS-A-6P-M
Broadband six-segmented λ/2 waveplate for 400-700 nm, SM1 mounted.
Overview
LBTek's Achromatic Six-Segmented Waveplate features a Liquid Crystal Polymer (LCP) layer sandwiched between two N-BK7 windows. The clear aperture is divided into six 60° angular segments, each with a uniformly aligned LCP fast-axis. The orientations alternate to produce spatially-varying half-wave retardance across the broadband VIS range (400-700 nm). Mounted in a standard SM1 housing (SMI-8A-SP with D-step) marked with segment orientation.
Key Features
- Achromatic broadband design: λ/2 retardance across 400-700 nm
- Six 60° angular segments with alternating fast-axis orientations
- Liquid Crystal Polymer between two N-BK7 windows
- Delay accuracy: ±λ/25 (band edges) to ±λ/50 (center band)
- Adjacent segment gap: < 150 μm
- Transmission > 70% (400-430 nm), > 96% (520-700 nm)
- Mounted in SMI-8A-SP housing with D-step, SM1 thread
Applications
- Structured-illumination microscopy
- Vector beam and structured light generation
- Region-resolved polarization modulation
- Polarization optics research and instrumentation
