OPB-30C05-P 30 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-30C05-P is a 30 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, uncoated and sourced from OptoSigma. This window is designed for use in optical systems where a flat, transparent surface is required to maintain the optical path without introducing aberrations or distortions.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This makes it an ideal choice for applications that require high precision and stability over a wide temperature range.

The window's flat shape ensures that it does not alter the direction of light passing through it, making it suitable for use in various optical systems such as beam expanders, laser systems, and imaging systems. The uncoated surface allows for maximum light transmission but may require additional coatings depending on the specific application.

The item data indicates a wavelength of 588 nm, suggesting that this window is designed for use in visible light applications. However, the window's high-quality N-BK7 material and flat shape make it suitable for use across a wide range of wavelengths and applications.
