OFB-20S03-4 20 x 20 mm N-BK7 Square Precision Ground Flat Window; t=3 mm Uncoated

OptoSigma offers the OFB-20S03-4, a 20 x 20 mm N-BK7 Square Precision Ground Flat Window with a thickness of 3 mm and no coating. This window is a type of flat optical component designed to provide a clear aperture with minimal optical aberration.

The OFB-20S03-4 is rectangular in base shape, making it suitable for various optical applications. Its geometry is defined by dimensions 'a' and 'b', each measuring 20 mm, and a thickness of 3 mm. This window is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications that use this wavelength. It has a shape described as a thin lens, which implies that it is thin relative to the diameter of the lens. This feature is beneficial in applications where the window's thickness needs to be minimized.

The OFB-20S03-4 is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of optical components, uncoated windows are often chosen for their simplicity, cost-effectiveness, and compatibility with various coatings that users may apply later.

According to the provided item data, this window is in stock and available for purchase, making it an ideal choice for users seeking immediate delivery.
