CASTECH's Photoelastic Modulators (PEMs) offer advanced capabilities for changing the polarization state of light through dynamic phase retardation. Utilizing isotropic materials that vibrate at their resonant frequency, these modulators leverage the photoelastic effect to periodically alter the refractive index and phase retardation of transmitted light. With features including large acceptance angles, wide wavelength ranges, and high modulation frequencies, CASTECH's PEMs are ideal for a variety of demanding optical applications.

Product Features:

• Dynamic Optical Waveguide: Utilizes periodic vibration of isotropic materials to change the polarization state of light.
• High Precision: Offers precise phase modulation with minimal signal distortion.
• Wide Wavelength Range: Suitable for ultraviolet, visible, and near-infrared bands (one-dimensional) and visible to infrared bands (two-dimensional).
• Large Acceptance Angle and Aperture: Ensures compatibility with various optical systems and applications.
• High Modulation Frequency: Capable of handling high-speed modulation requirements.

Types:

• One-Dimensional PEMs: Feature single vibration dimension, suitable for ultraviolet, visible, and near-infrared applications.
• Two-Dimensional PEMs: Offer dual vibration dimensions for a broader range of phase modulation, ideal for visible and infrared bands.

Applications:

• Polarization Measurement: Accurate detection and analysis of light polarization.
• Quantum Sensing: Enhances precision in quantum measurement technologies.
• Spectrometer: Improves spectral analysis with precise phase control.
