OFB-12.7C05-10 12.7 mm Dia. N-BK7 Round Precision Ground Flat Window; t=5 mm Uncoated

The OFB-12.7C05-10 is a high-precision flat window offered by OptoSigma, a leading global provider of optical components. This window is designed with a base shape of a circle, making it suitable for a wide range of applications where uniformity and consistency are key.

The window has a diameter of 12.7 mm, providing a substantial surface area while maintaining a manageable size. The thickness of the window is 5 mm, striking a balance between durability and light transmission. The N-BK7 material, a high-quality borosilicate glass, ensures excellent optical performance and chemical resistance. This material is specifically identified as "n-bk7 schott" in the item data, indicating its compliance with the rigorous standards set by Schott, a renowned glass manufacturer.

The OFB-12.7C05-10 is designed for use at a wavelength of 588 nm, making it suitable for applications in the visible light spectrum. Its shape is defined as a "Thin Lens," suggesting that it may have some light-focusing capabilities, although this is not its primary function.

Notably, this window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may be desirable in certain applications where a bare glass surface is required, or where additional coatings could introduce unwanted complexities or costs.
