BS049 30:70 (R:T) Non-Polarizing Beamsplitter Cube; 10 mm 400-700nm

The BS049 is a high-quality non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is part of Thorlabs' extensive catalog, featuring a robust design and reliable performance. The cube has a side length of 10 mm, making it suitable for a wide range of optical applications.

The beamsplitter cube is designed to operate within the wavelength range of 400-700 nm, with a reflection ratio of 30% and a transmission ratio of 70%. This specific beamsplitter cube is coated with Thorlabs' proprietary coating, referred to as 'tho cbs bbar400-700', on all surfaces, ensuring high-quality performance across the specified wavelength range.

The BS049 is made from n-BK7 Schott glass, a material known for its excellent optical properties and wide transparency range. The beamsplitter cube's shape is a cube, which is a standard in the industry due to its simplicity and robustness.

This beamsplitter cube is a 30:70 (R:T) non-polarizing beamsplitter, meaning it splits incoming light equally between the reflected and transmitted paths, regardless of the polarization state of the light. This makes it a versatile component in many optical systems.
