PS908L-A N-BK7 Right Angle Prism; 20 mm ARC 350-700nm Legs

The PS908L-A is a right-angle prism made from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and wide transparency range. This prism, sourced from Thorlabs, is designed with a 20 mm arc and features anti-reflection coatings (AR) on both the front and right faces, optimized for the 350-700 nm wavelength range.

The prism's geometry is defined by its 28.3 mm width (x) and 20 mm length (l), making it suitable for various applications that require a compact, high-performance prism. Its right-angle design allows for efficient light reflection, making it an ideal component in systems requiring precise light direction and control.

The PS908L-A's coating is a broadband anti-reflection type, denoted as 'tho a bbar'. This coating significantly reduces surface reflections, thereby enhancing the prism's transmission efficiency and overall system performance. The coating's durability ensures the prism maintains its high-performance characteristics even under demanding conditions.
