OPB-150C15-10-5 150 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=15 mm Uncoated

The OPB-150C15-10-5 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 that is 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 in this window is sourced from Schott, a leading manufacturer of optical glass.

The window is designed for use at a wavelength of 588 nm, which falls within the yellow-green region of the visible light spectrum. This makes it suitable for applications that involve yellow-green light, such as certain types of fluorescence microscopy.

The window has a shape described as a thin lens, which means it has a very small curvature. This makes it ideal for use as a flat window, where it can be used to seal off an optical system while minimally affecting the path of light.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to it. This can be beneficial in certain applications where a natural surface is desired, or where the cost of additional coatings is a concern. However, it should be noted that uncoated windows can have higher reflectivity than coated windows, which could impact the performance of some optical systems.

The window is currently in stock and available for purchase through the OptoSigma website.
