Product Description

l Design wavelength: 405 nm, 532 nm, 633 nm, 780 nm, 808 nm, 830 nm, 850 nm, 1030 nm, 1064 nm, and 1550 nm

l Extinction ratio (Tp:Ts): >3000:1

l Application: separating P-polarized light and S-polarized light

     The Tuniu Laser Line Polarizing Beamsplitter Cube consists of two UV fused silica right-angle prisms, with a dielectric beamsplitter coating that reflects S-polarized light and transmits P-polarized light. All four sides of the cube can serve as incident surfaces to separate P-polarized and S-polarized light. For optimal polarization performance, it is recommended that the incident light enters from the right-angle side of the prism coated with the polarizing beamsplitter film (the prism marked with a black dot on top indicates that its hypotenuse is coated with the dielectric polarizing beamsplitter film). The extinction ratio of the laser line polarizing beamsplitter cube is Tp:Ts > 3000:1, and all four light-transmitting surfaces are coated with V-type anti-reflection coatings designed for the single wavelength. The reflectance of the anti-reflection coating is less than 0.25% at the design wavelength. Tuniu offers 10 design wavelength options of 405 nm, 532 nm, 633 nm, 780 nm, 808 nm, 830 nm, 850 nm, 1030 nm, 1064 nm, and 1550 nm. Custom services for other design wavelengths and special sizes are available. For customization needs, please contact the technical support.

Attributes

Laser Line Polarizing Beamsplitter Cubes

l M3 threaded holes on the side, compatible with the 30 mm coaxial systems

l Four SM1 internal threads on the side, compatible with SM1 lens tubes for installation

l Four light-transmitting surfaces with V-type anti-reflection coatings Rabs<0.25%@design wavelength

     Tuniu integrates the 25.4 mm laser line polarizing beamsplitter cube in a cube housing compatible with the 30 mm coaxial systems, with a top scribed line indicating the optical path direction. The housing features M3 threaded holes on the sides for compatibility with the 30 mm coaxial systems. Additionally, the housing provides four SM1 internal threaded ports on the sides, allowing simultaneous compatibility with 25.4 mm lens tubes. Moreover, the coaxial cube is equipped with M4 threaded holes at the bottom for mounting posts.

Laser Line Polarizing Beamsplitter Cubes, Unmounted

l Four light-transmitting surfaces with V-type anti-reflection coatings Rabs<0.25%@design wavelength

     Tuniu offers 10 design wavelength options of 405 nm, 532 nm, 633 nm, 780 nm, 808 nm, 830 nm, 850 nm, 1030 nm, 1064 nm, and 1550 nm. The prism marked with a black dot on top indicates that its hypotenuse face is coated with a dielectric polarizing beamsplitter coating, which reflects S-polarized light and transmits P-polarized light. Any of the four sides can serve as the incident surface to separate P-polarized and S-polarized light. For optimal polarization performance, it is recommended that the incident light enters from the right-angle side of the prism coated with the polarizing beamsplitter coating.
