LBTEK Narrowband Polarizing Beamsplitter Cube Kit is composed of two Right-Angle Prisms, one of which has a dielectric polarizing Beamsplitter Coating on its hypotenuse. The dielectric Beamsplitter Coating can reflect S-polarized light and transmit P-polarized light, achieving separation of P-polarized light and S-polarized light along the transmission direction and the 90° reflection direction. Compared with broadband Polarizing Beamsplitter Cubes, the Beamsplitter Coating and Antireflection Coating (AR Coating) of narrowband products are optimized for a defined wavelength range, enabling a higher Extinction Ratio (ER) (Tp:Ts > 2000:1) and better beamsplitting performance within the wavelength range. The Narrowband Polarizing Beamsplitter Cube Kit consists of 10 Polarizing Beamsplitter Cubes with the same wavelength range and 12.7×12.7×12.7 mm dimensions, and the wavelength range covers five commonly used wavelength ranges in the field of Quantum Technologies precision measurement: 420-495 nm, 505-680 nm, 620-795 nm, 800-950 nm, and 975-1100 nm. In addition to the standard Narrowband Polarizing Beamsplitter Cube Kit, LBTEK also provides a variety of custom solutions, including custom special sizes, wavelength ranges, Extinction Ratio (ER), and other specifications. For specific custom requirements, please contact LBTEK technical support.

LBTEK Narrowband Polarizing Beamsplitter Cube Kit separates the P-Polarization and S-Polarization in the Incident Beam through a dielectric polarizing Beamsplitter Coating. The P-Polarization is transmitted along the original direction (transmission efficiency Tp,avg > 90%), while the S-Polarization is reflected in the perpendicular direction (reflection efficiency Rs,avg > 95%). The Extinction Ratio (ER) can reach Tp:Ts > 2000:1. All four sides of the cube can serve as the Incident Surface. To achieve the best polarization performance, it is recommended that the Incident Beam enter through the right-angle face of the Prism coated with the polarizing Beamsplitter Coating. The narrowband Coating design enables the Beamsplitter Coating and AR Coating to achieve better polarization performance within the Wavelength Range, making it suitable for laser systems with a fixed Wavelength Range and high Extinction Ratio requirements, as well as polarization Optical Experiments. The Narrowband Polarizing Beamsplitter Cube has a compact size. It can be clamped by an LBTEK cube adapter mount (such as the CM-3 cube mount) and is compatible with a 30 mm Cage System for installation and use. It can also be used with a cage system to build a stable polarization Optical Path.

LBTEK narrowband Polarizing Beamsplitter Cube, together with a beamsplitter cube adapter, is mounted on a coaxial cube mount
