Description
Overview
Applications
Handling and identification
Technical specifications
- Polymer retarder film designed to modify the polarization state of transmitted light. Available in quarter-wave (λ/4, WP140HE), half-wave (λ/2, WP280) and one-wave (1λ, WP560) retardation types.
- WP140HE (λ/4) and WP280 (λ/2) are single-layer modified polycarbonate achromatic retarders; WP560 (1λ) is manufactured by laminating two λ/2 films to achieve approximately 560 nm retardation.
- Optical performance maintained up to 90°C; mechanical integrity up to 80°C.
Applications
- Circular polarizers and display modules (LCDs).
- Fiber-optic components, polarization control in coherent optical systems, machine vision and laser instrumentation.
- Industrial and laboratory polarization assemblies requiring specified retardation values.
Handling and identification
- Main appearance: thin polymer sheet supplied with a removable protective film.
- Protective film includes a black stripe marking the fast axis for alignment during assembly.
- Manufacturers should observe recommended operating temperatures and avoid exposure above specified thermal limits.
Technical specifications
- Material: modified polycarbonate (single-layer for λ/4 and λ/2; laminated construction for 1λ).
- Part identifiers: WP140HE (λ/4), WP280 (λ/2), WP560 (1λ).
- Transmission: WP140HE achieves >90% transmission across 450–700 nm.
- Construction: WP560 produced by laminating two WP280 (λ/2) films to reach ~560 nm retardation.
- Thermal limits: optically sound up to 90°C; mechanically sound up to 80°C.
- Form factors: round, square or rectangular sheets can be manufactured to a wide range of sizes.
