PW4037UV 4 in Dia. UVFS Round Plane Optical Window; t=0.375 in Uncoated

The PW4037UV is a 4-inch diameter UVFS round plane optical window, uncoated, with a thickness of 0.375 inches. This window is sourced from Laser Components, a reputable vendor in the optical industry.

The window is designed for use in flat optical systems, offering a clear aperture for the transmission of light. The circular shape, with a diameter of 101.6 millimeters, is a common choice for applications requiring a wide field of view. The thickness of the window, at 9.525 millimeters, provides structural integrity while minimizing optical distortion.

The UVFS material, identified as UVFS Mal-1965, is specifically designed for use in the ultraviolet spectrum, making this window ideal for applications in UV photonics, spectroscopy, and other UV-based technologies. The window is uncoated, offering bare substrate transmission characteristics. However, coatings can be applied to enhance the window's performance, such as anti-reflective coatings to increase transmission or AR/HR coatings to manage reflection and heat.

The window's wavelength is specified at 632.8 nanometers, a common reference wavelength in the visible spectrum. However, its UVFS material makes it suitable for use in the ultraviolet spectrum, typically below 400 nanometers.
