BS058 70:30 (R:T) Non-Polarizing Beamsplitter Cube; 10 mm 400-700nm

The BS058 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is part of Thorlabs' extensive catalog, boasting a 70:30 (R:T) split ratio, making it ideal for applications requiring a higher reflection than transmission.

The cube features a 10 mm side, ensuring a substantial optical path length while maintaining a compact form factor. The beamsplitter's coating, tho cbs bbar400-700, is applied to all surfaces, including the front, back, left, right, hypotenuse 1, and hypotenuse 2, ensuring consistent performance across all reflected and transmitted beams.

This beamsplitter cube is designed to operate within the wavelength range of 400-700nm, with a center wavelength of 633nm. The material used for the cube is n-bk7 schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence.

The BS058 is currently in stock and available for immediate purchase through the Thorlabs website. For more information, including technical specifications and purchasing options, please refer to the provided weblink.
