OPB-30S03-1-5 30 x 30 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-30S03-1-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This window is rectangular in shape, with dimensions of 30 x 30 mm, making it suitable for use in applications where a larger aperture is required.

The window is made from N-BK7 glass, a popular material for optical components due to its excellent optical properties. This type of glass, also known as Schott glass, has a refractive index of approximately 1.5168 at a wavelength of 588 nm, which is ideal for use in visible light applications.

The window has a thickness of 3 mm, which provides a good balance between mechanical strength and optical performance. It is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where a high level of transmittance is required, as coatings can sometimes introduce unwanted reflections or absorption.

According to the vendor, this item is currently in stock and can be purchased directly from the OptoSigma website. The website also provides additional technical specifications and details about the window, which can be useful for those looking to integrate it into their optical systems.
