OPB-30S03-10-5 30 x 30 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-30S03-10-5 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, a popular optical glass known for its excellent optical properties. This material, also known as BK7, is renowned for its low dispersion and high transmission in the visible spectrum, making it an ideal choice for a wide range of optical applications. The window has a thickness of 3 mm, providing a good balance between strength and weight.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable, as it can simplify the design and reduce the cost of the optical system. However, it should be noted that uncoated windows can exhibit higher levels of reflection, which may need to be taken into account in the system design.

The window is flat, meaning its surfaces are parallel to each other. This is important in applications where maintaining the integrity of the optical path is critical, such as in beam delivery systems or interferometry.

According to the vendor's website, this window is in stock, indicating that it is readily available for purchase and delivery. This can be a significant advantage in situations where time is of the essence or where rapid prototyping or replacement of components is needed.
