OPB-50.8C05-10-5 50.8 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-50.8C05-10-5 is a circular optical flat window, sourced from OptoSigma, with a diameter of 50.8 mm and a thickness of 5 mm. This window is made of N-BK7, a type of borosilicate glass known for its excellent optical properties, including low optical dispersion and high homogeneity. The N-BK7 material is sourced from Schott, a renowned manufacturer of high-quality optical glass.

This optical flat window is designed for use in parallel optical systems, where it provides a clear, undistorted view of the optical path. The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where the natural properties of the glass are desired.

The window's geometry is defined by its diameter and thickness. With a diameter of 50.8 mm, it is suitable for a wide range of optical systems. The thickness of 5 mm provides structural rigidity while minimizing optical distortion.

The window's wavelength is 588 nm, which is in 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.
