Product Description

l Various design wavelengths available within the range of 405 nm-1600 nm

l Composed of a half-wave plate and a polarizing beamsplitter cube

l Commonly used for continuously adjusting the transmission intensity of linearly polarized light beams

     The Tuniu Tunable Polarizing Beamsplitter consists of a half-wave plate mounted in an RM05 rotation mount and a polarizing beamsplitter cube installed in a 30 mm coaxial cube mount. The combination of the half-wave plate and polarizing beamsplitter cube enables continuous variation of the transmission intensity of linearly polarized incident light. It can also be used individually to meet specific beam splitting requirements. Tuniu offers two types (single-point and broadband) with a total of 13 optional design wavelengths , along with a high-power laser line version. Tuniu provides various customization services, including specific design wavelength, size, and etc. For any customization needs, please contact Tuniu Technical Support.

Laser Line Tunable Polarizing Beamsplitters·

l Design wavelength: 9 options available within the range of 405 nm-1550 nm range

l Extinction ratio (Tp:Ts): >2000:1

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

     Tuniu assembles a quartz air-spaced half-wave plate mounted in the RM05 rotation mount with a laser line polarizing beamsplitter cube installed in a 30 mm coaxial cube mount to form a laser line tunable polarizing beamsplitter. The top scribed line indicates the optical path direction, with the fast axis of the waveplate aligned to the 0° scribed line on the rotation mount. The initial position is preset and locked, ensuring the waveplate does not alter the polarization direction of the incident light. The included wrench can be used to loosen and rotate the half-wave plate for continuous adjustment of the transmission intensity of the linearly polarized light.

High-Power Laser Line Tunable Polarizing Beamsplitters

l Design Wavelength: 13 options available within the range of 266 nm-1550 nm

l Extinction Ratio (Tp:Ts): >2000:1

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

l Suitable for high-power applications

     Tuniu assembles a quartz air-spaced half-wave plate installed in the RM05 rotation mount with a high-power laser line polarizing beamsplitter cube mounted in a 30 mm coaxial beamsplitter cube mount to create a high-power laser line tunable polarizing beamsplitter. The top scribed line indicates the optical path direction, with the fast axis of the waveplate aligned to the 0° scribed line on the rotation mount. The initial position is preset and locked, ensuring the waveplate does not alter the polarization direction of the incident light. The included wrench can be used to loosen and rotate the half-wave plate for continuous adjustment of the transmission intensity of the linearly polarized light.

Broadband Tunable Polarizing Beamsplitters

l Design Wavelength: 420-680 nm, 700-1000 nm, 900-1100 nm, 1200-1600 nm

l Extinction Ratio (Tp:Ts): >1000:1

l Four light-transmitting surfaces with anti-reflection coatings Rabs<0.5%@design wavelength

     Tuniu mounts the achromatic half-wave plate in an RM05 rotation mount and assembles it with a broadband linear polarizing beamsplitter cube installed in a 30 mm coaxial cube mount to form a broadband tunable polarizing beamsplitter. The top scribed line indicates the optical path direction, with the fast axis of the waveplate aligned to the 0° scribed line on the rotation mount. The initial position is preset and locked, in which case the waveplate does not alter the polarization direction of the incident light. The included wrench can be used to loosen and rotate the half-wave plate to achieve continuous adjustment of the transmission intensity of the linearly polarized light.
