OPB-150C15-1-5 150 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=15 mm Uncoated

The OPB-150C15-1-5 is a high-quality optical window offered by OptoSigma. This window, with a base shape of a circle, has a diameter of 150 mm and a thickness of 15 mm, making it suitable for a wide range of optical applications.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material, also known as BK7, is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum. The specific type of N-BK7 used here is from Schott, a leading manufacturer of optical glass, ensuring top-notch quality.

The window is designed for use at a wavelength of 588 nm, which falls within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam delivery systems, and more.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired, or where additional coatings might interfere with the system's operation.

The window is classified as a flat window, indicating that its surfaces are parallel to each other. This is crucial in applications where maintaining a straight path for light is essential, such as in interferometry or beam splitting.
