S-OPB-30C05-10-5 30 mm Dia. N-BK7 Reasonable Round Optical Flat Window; t=5 mm Uncoated

The S-OPB-30C05-10-5 is a high-quality optical flat window offered by OptoSigma. This window, designed for general use, features a 30 mm diameter and a thickness of 5 mm, making it a versatile and robust option for various optical applications.

The window is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material, often used in high-precision optical systems, ensures minimal optical distortion and maintains consistent performance across a wide range of wavelengths, with a center wavelength of 588 nm specified for this particular window.

The window's geometry is defined as a thin lens, indicating its suitability for use in systems where minimal thickness is required or preferred. Despite its thin profile, the window's 5 mm thickness provides sufficient structural integrity for most applications.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other surface coatings. While coatings can enhance performance in specific applications, an uncoated window can be advantageous in situations where broadband transmission is required, or where the introduction of a coating might compromise the system's performance.
