OPSH-25C02-P 25 mm Dia. Sapphire Round Flat Window; t=2 mm Uncoated

The OPSH-25C02-P is a 25 mm diameter Sapphire Round Flat Window, with a thickness of 2 mm, sourced from the reputable vendor OptoSigma. This window is a type of optical component designed for use in various applications, primarily functioning to provide protection for the optical system while minimally affecting the beam.

The window's base shape is circular, which is a common choice due to its ease of integration and uniform distribution of stress. The geometry, defined by a diameter of 25 mm and a thickness of 2 mm, ensures a robust and compact design, suitable for a wide range of applications.

The material of this window is sapphire, specifically identified as "sapphire ow mal-1972". Sapphire is a highly desirable material in optical applications due to its excellent properties, such as its high transparency across a broad spectrum, including the visible and infrared regions, and its exceptional hardness, which provides superior durability and resistance to scratching.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where the natural properties of sapphire are desired, or where cost or simplicity are considerations.

The window is designed to operate at a wavelength of 588 nm, which is in the yellow-orange region of the visible spectrum. However, due to sapphire's broad transparency, it can be used in applications outside this wavelength.
