Achromatic Half-Wave Plate, λ/2, 700–900 nm (Ø25.4 mount)
O-AHWP-25.4-BL272Design Tools
Complete Your Setup
Overview
This achromatic waveplate uses a compound birefringent design to hold a near-constant retardance across a broad wavelength band, suppressing the chromatic dispersion that limits conventional single-material waveplates and keeping polarization performance consistent for multi-wavelength sources. A half-wave (λ/2) plate rotates the plane of linearly polarized light.
Applications
- Broadband / multi-wavelength polarization control
- Fiber-optic communication
- Laser modulation
- Microscopy & imaging systems
Construction & Performance
- Substrate: Crystalline Quartz
- Retardance: λ/2
