BS028 90:10 (R:T) Non-Polarizing Beamsplitter Cube; 1 inch 400-700nm

The BS028 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is part of the extensive catalog of optical elements offered by 3DOptix, a leading developer of advanced optical simulation software.

The BS028 features a 1-inch cube side, making it compatible with a wide range of optical systems. It is designed to operate within the wavelength range of 400-700nm, making it suitable for a broad spectrum of applications.

The beamsplitter has a reflection ratio of 90:10 (R:T), meaning it reflects 90% of the incident light and transmits 10%. This ratio is consistent across the entire wavelength range, ensuring predictable and reliable performance.

The BS028 is coated with Thorlabs' proprietary coating, identified as 'tho cbs bbar400-700'. This coating is applied to all surfaces of the cube, including the front, back, left, right, and both hypotenuses. This ensures consistent performance across all surfaces and in all orientations.

The BS028 is made from n-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. This makes the beamsplitter cube suitable for high-power applications.
