2. General Description

Waveplates, also known as retarder plates, are optical components that introduce a delay between two orthogonal polarization components of light, creating a change in the polarization state of the transmitted light. These devices are made from high-quality materials such as quartz, sapphire, or fused silica to ensure minimal optical distortion and high transmission efficiency. Waveplates are essential in applications requiring fine control over polarization, such as in the manipulation of laser beams, optical testing, microscopy, and spectroscopy.

A waveplate operates based on the principle of birefringence, where the speed of light varies depending on the polarization direction. By controlling the thickness and material properties of the waveplate, the amount of phase shift introduced between the orthogonal components of the light can be precisely adjusted. This phase shift enables the conversion of linearly polarized light into circular or elliptical polarization, or vice versa, depending on the application.

Waveplates can be tailored to specific wavelengths, with the most common types being the half-wave and quarter-wave plates, which introduce phase shifts of 180° and 90° respectively. These are crucial in applications such as polarization switching, polarization analysis, and laser alignment.

• Humidity Test: No peeling, scratches, or defects are observed after the test in a 49°C environment with 95%-100% humidity for 24 hours.
• Solvent and Cleaning Testing: No peeling or scratches are observed after exposure to acetone and alcohol for 10 minutes, followed by air drying and cleaning.
• Salt Spray Test: The film shows no damage after being subjected to 100 hours in a 35°C environment with 5% saltwater concentration.
