Beamsplitter (BSP1104)
A beamsplitter is an optical element, typically a flat-plate structure with a special coating. Its working principle is to split an incident light beam into two parts: one reflected and one transmitted, thereby achieving precise control of the light path distribution.

Fiber Beamsplitter
Beam Splitters
Bogaolaser
Configure: 1×2 Grade: Class A Central Wavelength [optional (Optional)]: 400-2000 optional (Optional)
Our splitters can be configured with different center wavelengths and fiber types to achieve customer-specified splitting ratios. They use fiber-fusion technology to divide power from one fiber equally or proportionally among outputs, or to combine light from multiple fibers into one fiber in reverse operation, with high transmission efficiency. Available splitting/coupling ratios include 50:50, 10:90, 15:85 and 1:99, with selectable wavelengths from 400-2000nm. Customization includes coupling structures such as 1x2, 1x4 and 2x2, power, wavelength, coupling ratio and connectors.

HPBS-High-Power Polarizing Beamsplitter Cube
Beam Splitters
Sunday-optics
Material: JGS1 Dimensions: 2、3、5、10、12.5、12.7、18、20、25、25.4、38.1、50.8、100mm Tolerance: -0.2 mm
The high-power polarizing beamsplitter cube comprises two precision UV-fused-silica right-angle prisms with special coatings on their hypotenuse faces, bonded together. It splits arbitrary incident light into perpendicular linearly polarized beams: all P polarization transmits along the incident direction, while all S polarization reflects perpendicularly. Custom Tp:Ts ratios greater than 1000:1, 2000:1 or 5000:1 are available. Special bonding replaces conventional optical cementing to meet laser and cutting requirements. Extremely high temperature resistance and strong laser resistance are key features. Typical laser wavelengths are 266, 355, 450, 532, 633, 760, 767, 780, 808, 905, 1064 and 1550 nm. Laser damage threshold reaches 15J/cm2@1064nm, 20ns, 20HZ.
