39-261 50.8 mm Dia. AR Coated Sapphire Protective Flat Window; t=3.15 mm NIR I 600-1050nm

The 39-261 is a high-quality protective flat window, boasting a generous 50.8 mm diameter, making it suitable for a wide range of applications. This window is fabricated from sapphire, a material renowned for its exceptional hardness, durability, and resistance to scratching, making it an ideal choice for demanding environments. The window has a thickness of 3.15 mm, providing a balance between strength and weight.

The 39-261 window features advanced Anti-Reflective (AR) coatings on both the front and back surfaces. These coatings are designed to the NIR-I standard curve, which covers the wavelength range of 600-1050nm. This coating significantly reduces reflective losses, enhancing the transmission of light through the window. The result is improved image quality and system performance, particularly in applications where high light transmission is critical.

This window is classified as a Flat Window, which means it has a simple, planar surface on both sides. This design ensures minimal optical distortion, making it suitable for applications where image fidelity is paramount. The window's Thin Lens shape further contributes to its minimal optical impact.
