OPB-30S05-4-5 30 x 30 mm N-BK7 Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPB-30S05-4-5 is a high-quality optical window from OptoSigma, designed for use in a wide range of optical systems. This particular model features a square base shape with dimensions of 30 x 30 mm, making it suitable for applications that require a larger aperture. The window has a thickness of 5 mm, providing a good balance between strength and light transmission.

The window is made from N-BK7, a popular optical glass due to its excellent optical properties. It has a refractive index of 1.5168 at a wavelength of 588 nm, which is within the visible light spectrum. This makes it an ideal choice for applications that require high light transmission and clarity.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in some reflective loss, it also means that the window is less susceptible to damage from environmental factors, making it a good choice for applications in challenging environments.
