G390043525 31.5 mm Dia. N-BK7 Optical Flat Window; t=3mm 725-1050nm

The G390043525 is a high-quality optical flat window, boasting a diameter of 31.5 mm and a thickness of 3 mm. This window is fabricated from N-BK7, a popular borosilicate crown glass known for its excellent optical properties, making it an ideal choice for a wide range of applications.

This optical window features a circular base shape, which is a common choice due to its uniform distribution of stress and ease of mounting. The window is coated with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating enhances transmission and reduces reflection across the visible spectrum and into the near-infrared, covering the wavelength range of 725-1050nm.

The window's shape is defined as thin lens, indicating its minimal curvature and negligible optical power. This makes it suitable for use as a protective window or a mounting interface in various optical systems without significantly altering the optical path.
