10B20NP.29 25.4 mm Dia. 50:50 (R:T) N-BK7 Laser Line Non-Polarizing Plate Beamsplitter; t=6.1mm 1064nm

This is a 10B20NP.29 Non-Polarizing Plate Beamsplitter from MKS/Newport, designed for use with laser line applications at a wavelength of 1064nm. The beamsplitter features a circular geometry with a diameter of 25.4mm and a thickness of 6.1mm, providing a robust and compact design suitable for various optical systems.

The beamsplitter is made of N-BK7 Schott, a popular material known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior transmittance in the visible and near-infrared regions. This specific beamsplitter has a 50:50 reflection-to-transmission ratio, ensuring an even split of the incoming light beam.

The front surface of the beamsplitter is coated with a New NP.29 coating, which is specifically designed for laser line applications. This coating ensures high damage threshold, low scatter, and minimal absorption, making it ideal for high-power laser systems.
