OFB-1015R05-20 10 x 15 mm N-BK7 Rectangular Precision Ground Flat Window; t=5 mm Uncoated

The OFB-1015R05-20 is a 10 x 15 mm N-BK7 Rectangular Precision Ground Flat Window, with a thickness of 5 mm, sourced from OptoSigma. This window is a type of optical element designed to allow light to pass through while minimizing distortion and reflection.

The window's rectangular shape, with dimensions of 10 mm in the a-axis and 15 mm in the b-axis, provides a larger surface area for light to pass through compared to circular windows of similar diameter. This can be beneficial in applications where a larger aperture is required.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a low coefficient of thermal expansion, high homogeneity, and excellent transmission in the visible and near-infrared regions. The wavelength of 588 nm falls within the visible light spectrum, indicating that this window is suitable for use in applications involving visible light.

The window has a thickness of 5 mm, which provides sufficient structural integrity while minimizing the risk of optical distortion caused by the window's own thickness. 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 optical properties of the glass are desired.

The OFB-1015R05-20 is available from OptoSigma and is currently in stock, according to the vendor's website. This window is a versatile optical element that can be used in a wide range of applications, from scientific research and development to industrial manufacturing and beyond.
