62-606 75 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm Uncoated

The 62-606 is a 75 mm diameter N-BK7 precision protective flat window with a thickness of 4 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements.

The window is designed as a flat window, which is a type of optical window that does not alter the path of light. It is made of N-BK7, a type of borosilicate glass that is known for its excellent optical properties, including a low coefficient of thermal expansion and a high Abbe number. This makes it an ideal choice for applications that require high precision and durability.

The window has a diameter of 75 mm and a thickness of 4 mm, making it suitable for applications that require a larger window size. Despite its size, the window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be beneficial in certain applications where coatings may interfere with the desired optical properties.

The window is designed for use at a wavelength of 587.6 nm, which is in the yellow-green region of the visible spectrum. This makes it suitable for applications that use light in this region, such as fluorescence microscopy or certain types of laser systems.
