CSMH-25-550 25 x 25 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter; t=25mm 400-700nm

The CSMH-25-550 is a high-quality beamsplitter cube designed for use in optical systems that require a 50:50 split of incident light. Manufactured by OptoSigma, this beamsplitter features a 25 x 25 mm aperture and a 25 mm thickness, making it suitable for a wide range of applications.

The beamsplitter is made from N-BK7 Schott glass, a popular choice for its excellent optical properties and high damage threshold. The front, back, left, and right surfaces are coated with ideal broadband anti-reflective (AR) coatings, ensuring minimal loss of light due to reflection.

The hypotenuse faces of the beamsplitter cube are coated differently. The first hypotenuse surface is coated with an Opt CSMH-550 coating, specifically designed for this type of beamsplitter. The second hypotenuse surface is coated with an ideal broadband AR coating, similar to the other surfaces.

The beamsplitter has a reflection ratio of 50:50 (R:T), meaning it reflects 50% of the incident light and transmits the remaining 50%. This makes it ideal for applications where equal distribution of light is required.

The CSMH-25-550 operates within a wavelength range of 400-700 nm, covering a broad spectrum of visible light. It is available for purchase directly from the OptoSigma website, where you can find more detailed specifications and purchasing information.
