G390138000 30 x 50 mm N-BK7 Optical Flat Window; t=4mm Uncoated

The G390138000 is a rectangular optical flat window, measuring 30 x 50 mm, with a thickness of 4mm. This window is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and high transparency in the visible spectrum. The window is sourced from Qioptiq Photonics, a reputable vendor in the field of precision optics.

The window's geometry is defined by its base shape, which is rectangular, and its thin lens shape. The thin lens shape is characterized by a small thickness compared to its other dimensions, which is beneficial for applications where minimal optical path difference is required.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where broadband transparency is required, or where specific coatings might interfere with the system's performance. However, it's important to note that uncoated windows can have higher reflectivity at optical interfaces, which might need to be considered in the system design.

The window is designed to operate at a wavelength of 633nm, making it suitable for a wide range of applications in the visible spectrum. The item data indicates that this window is in stock and available for purchase, making it a readily available option for users seeking an N-BK7 optical flat window with these specifications.
