Free-Space Magneto-Optic Isolator
The Faraday rotator is a non-reciprocal magneto-optical device based on the Faraday effect, which can rotate the polarization direction of the incident ray polarized light by a certain angle, generally set to rotate 45°; the rotation direction of light is only related to the direction of the internal magnetic field, when the light beam passes through the Faraday rotator, the polarization state of the light will rotate 45° in the same direction; the Faraday rotator cooperates with the polarizer to block the return light in the optical path and realize the one-way passage of light. The Faraday isolator is mainly composed of a polarizer, Faraday rotator and analyzer. This product is a polarization-dependent isolator, which can effectively block the return light and protect the laser device.

Non-polarizing beamsplitter prism (NPBS) UBPBS032
Polarization Optics
Uni-lens
Dimensions: 3.2 mm × 3.2 mm × 3.2 mm Standard Wavelength [Optional standard wavelengths, not a continuous overall range]: 450-680, 650-850, 900-1200, 1250-1570, 1500-1610 nm Material: N-SF2 grade A optical glass
A non-polarizing beamsplitter (NPBS), also called an NPBS cube beamsplitter, is a more complex type made from two right-angle prisms joined at their hypotenuse faces. Before bonding, the cementing face of one prism receives a metal-dielectric coating with the required reflection characteristics, a specified reflection percentage, and color. Coating absorption loss is minimized, and transmission and reflection ratios can be set to 10%, 20%, 30%, 40%, 50%, and other values.

Glan-Taylor prism
Polarization Optics
100optics
Material: α-BBO，Calcite or YVO4 Wavelength Range [Material=α-BBO]: 200-3500 nm Extinction Ratio [Material=α-BBO]: ＜5×10⁻⁶
Glan Taylor Polarizer is made of two same birefringence material prisms which are separated by an air space. The polarizer with on side escape window is suitable for low to medium power application. Glan Taylor Polarizer will divide an entering unpolarized beam into beam rays, one is the extraordinary that is transmitted through the other side, and another is the ordinary ray that is totally internally reflected absorbed.
