OPB-25C05-20-2 25 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-25C05-20-2 is a high-quality optical window from OptoSigma, designed with precision and durability in mind. This window features a base shape of a circle with a diameter of 25 mm, making it suitable for a wide range of optical applications. The window has a thickness of 5 mm, providing excellent structural integrity and rigidity.

The material used for this window is N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is sourced from Schott, a leading manufacturer in the optical industry, ensuring high quality and reliability. The N-BK7 material is particularly suitable for applications that require high transmission in the visible spectrum, with a wavelength of 588 nm.

The window is designed in the shape of a thin lens, which is a simple lens that has a very small thickness compared to its diameter. This design ensures minimal optical aberrations and distortions, providing clear and accurate optical transmission.

The window is uncoated, meaning it does not have any additional layers or coatings applied to its surface. This can be beneficial in applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it's important to note that uncoated windows may have higher reflectivity and may not perform as well in extreme environmental conditions.
