OPB-40C06-4-5 40 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=6 mm Uncoated

The OPB-40C06-4-5 is a high-quality optical window from OptoSigma, designed with precision and durability in mind. This window boasts a 40 mm diameter and a thickness of 6 mm, making it suitable for a wide range of optical applications.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 Schott variant used in this window ensures superior optical performance.

The window is designed for use at a wavelength of 588 nm, making it ideal for applications that require high transmittance at this wavelength. The window's flat shape and thin lens design further enhance its optical performance, ensuring minimal distortion and high light transmission.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance certain optical properties, an uncoated window can be advantageous in certain applications, such as where broadband anti-reflection is not required.

The window's vendor, OptoSigma, is a reputable manufacturer of optical components, ensuring reliable and consistent quality. The current status of this item is 'In Stock', indicating its availability for immediate purchase and use.
