Wire grid polarizerComposed of parallel metal lines arranged precisely according to rules, with spacing much smaller than the wavelength of light. When natural light passes through a wire grid polarizer, according to electromagnetic theory, light with a polarization direction parallel to the metal wire will be absorbed and reflected, while light with a polarization direction perpendicular to the metal wire can pass through, making the transmitted light polarized.

Features:

1. Wide wavelength range: The wire grid polarizer using nanowire grid technology can cover wavelengths from ultraviolet to infrared, meeting the requirements of different application scenarios for light wavelengths.

2. Extinction ratio: Some wire grid polarizers have an extinction ratio of over 800:1 within a specific wavelength range, which can effectively distinguish different polarization states of light and output high-purity polarized light.

3. Large incident angle: Some wire grid polarizers can achieve spectral flatness performance at incident angles up to 45 °, which has certain advantages when used as polarizing beam splitters.

4. Good heat resistance: If the square wire grid polarizer is not installed, the working temperature can reach -40 ℃ to 200 ℃, and it can work stably in a wide temperature range.

　　Wire grid polarizerSuggestions for operation and maintenance:

1. Operating standards:

Do not directly touch the surface of the metal wire grid with your hands. It is recommended to use a vacuum suction pen or optical tweezers for operation.

When adjusting the direction of the polarization axis, it is preferable to choose a rotating frame design to avoid offset errors caused by manual rotation.

2. Storage conditions:

Store in a dry and dust-free environment (humidity<30%) with a temperature range of -20 ℃ to 40 ℃, avoiding contact with corrosive gases.

Can be paired with optical grade protective film for protection, reducing the risk of scratches.

3. Cleaning method:

Gently wipe with high-purity nitrogen or isopropanol to avoid corrosion of metal lines caused by the use of organic solvents.
