OPB-30S03-4-5 30 x 30 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-30S03-4-5 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 in the optical industry due to its excellent optical properties and high damage threshold. This specific window has a thickness of 3 mm, providing a good balance between mechanical strength and light transmission.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural reflectivity of the glass surface is desired or where the cost of additional coatings is a concern. However, it should be noted that uncoated windows can have higher reflectivity, which may affect the performance of some optical systems.
