OPB-25.4C05-4-5 25.4 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-25.4C05-4-5 is a 25.4 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, uncoated. This component is sourced from OptoSigma, a reputable vendor in the optical industry.

This optical window is designed for use in various applications where transparency and minimal optical distortion are required. The N-BK7 material, also known as BK7, is a popular choice due to its excellent optical properties, including a high refractive index and low dispersion. This makes it an ideal material for a wide range of optical components.

The window's flat design ensures that it does not introduce any curvature-induced aberrations, making it suitable for use in systems where precise optical path control is necessary. The 5 mm thickness provides sufficient mechanical strength while maintaining minimal optical thickness, thereby minimizing unwanted reflections and phase shifts.

The uncoated nature of this window means it does not have any anti-reflective or other surface coatings. This may be desirable in applications where such coatings are not required or could introduce unwanted effects. However, it should be noted that uncoated surfaces can reflect up to 4% of incident light, which may need to be considered in system design.
