BS042 10:90 (R:T) Non-Polarizing Beamsplitter Cube; 0.5 inch 1100-1600nm

The BS042 is a Non-Polarizing Beamsplitter Cube, designed for use in optical systems where the polarization of light is not a concern. This beamsplitter features a 0.5-inch cube side, making it compatible with a wide range of optical components.

The beamsplitter has a reflection rate of 0.1 and a transmission rate of 0.9 at the specified wavelength of 633nm. This means that approximately 10% of the incident light will be reflected, while 90% will be transmitted. The beamsplitter is designed to operate within the wavelength range of 1100-1600nm, making it suitable for near-infrared applications.

The BS042 is made from n-bk7 Schott glass, a material known for its excellent optical properties and high damage threshold. The beamsplitter features a coating on all surfaces (front, back, left, right, hypotenuse 1, and hypotenuse 2) with the code tho cbsbbar1100-1600. This coating is designed to optimize the beamsplitter's performance within the specified wavelength range.

The BS042 is available from Thorlabs, a leading vendor in the field of optical components. According to the vendor's website, the beamsplitter is currently in stock, ensuring quick delivery times. The beamsplitter's catalog number is BS042, and more information can be found on Thorlabs' website using this number.
