OPB-20C05-4-5 20 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-20C05-4-5 is a 20 mm diameter N-BK7 round optical parallel flat window with a thickness of 5 mm, sourced from OptoSigma. This window is a type of flat window, designed with a base shape of a circle, which is a common geometry in optical systems due to its symmetry and ease of alignment.

The window is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and wide transmission range. This specific N-BK7 is from Schott, a renowned glass manufacturer, ensuring high quality and reliability. The window is designed for a wavelength of 588 nm, making it suitable for applications that operate in this region of the spectrum.

The window is shaped as a thin lens, which is a lens of negligible thickness. This shape is often used in optical systems where the thickness of the lens does not significantly affect the optical path. The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable.

According to the vendor's website, this item is currently in stock, making it readily available for immediate use or integration into optical systems. The window's specifications and properties make it a versatile component for various applications in the field of optics and photonics.
