39-273 25 mm Dia. Borofloat33 Protective Flat Window; t=1.1 mm Uncoated

The 39-273 is a 25 mm diameter, 1.1 mm thick uncoated Borofloat33 protective flat window, sourced from Edmund Optics. This window is a flat, circular optical component designed for general-purpose use in various applications.

The window is made of Borofloat33, a low-expansion borosilicate glass with excellent optical transmission properties. It is particularly suitable for use in the visible and near-infrared regions of the spectrum, with a specified wavelength of 587.6 nm. The window's thin lens shape further enhances its optical performance.

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 such coatings may not be desired or necessary. However, it's important to note that uncoated surfaces can reflect a small percentage of incident light, which may need to be considered in the overall system design.
