Polymer True Zero-Order Half-Wave Plate — HWP13-405A-M

Polymer True Zero-Order Half-Wave Plate — Model HWP13-405A-M

Polymer λ/2 waveplate at 405 nm, wide-AOI tolerance, mounted or unmounted.

Overview

LBTek's Polymer True Zero-Order Half-Wave Plates use a Liquid Crystal Polymer film sandwiched between N-BK7 windows to deliver λ/2 retardance at the design wavelength. The polymer construction provides exceptional angular tolerance (±15° AOI), broad operating temperature range, and polarization stability across the full clear aperture. Available in 39 discrete design wavelengths from 405 nm to 1550 nm with optional SM05 or SM1 mechanical housing.

Key Features

• Liquid Crystal Polymer / N-BK7 sandwich construction for λ/2 retardance
• True zero-order single-element design — superior thermal/spectral stability
• Wide angular tolerance: ±15° angle of incidence
• Operating temperature: -20 to 80 °C
• Anti-reflection coating optimized for the design wavelength band
• Available unmounted (bare) or pre-mounted in standard SM05/SM1 housing
• Standard wavelengths: 405 nm to 1550 nm (39 discrete design points)

Applications

• Polarization state conversion (linear ↔ circular / elliptical)
• Imaging polarimetry, ellipsometry, isolator-free laser trains
• Quantum optics and photonic research
• Display panel polarization management
