PW1619C 40 mm Dia. N-BK7 Round Plane Optical Window; t=5 mm Uncoated

The PW1619C is a 40 mm diameter N-BK7 round plane optical window with a thickness of 5 mm, uncoated and sourced from Laser Components. This window is designed to provide a clear, unobstructed view of the optical path while minimizing optical losses.

The window is made of N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is widely used in the optical industry for its superior performance and reliability.

The window features a flat, plane surface on both sides, ensuring a clear, undistorted view of the optical path. The 40 mm diameter provides a wide field of view, making it suitable for a variety of applications. The 5 mm thickness offers a good balance between strength and weight, ensuring durability without adding unnecessary bulk.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where coatings may interfere with the optical path or are not necessary. However, it's important to note that uncoated windows can have higher reflective losses than coated ones.

The window is in stock and available for immediate purchase. For more detailed specifications and performance data, please refer to the vendor's datasheet.
