63-208 30 mm Dia. Calcium Fluoride Protective Flat Window; t=3 mm Uncoated

The 63-208 is a 30 mm diameter Calcium Fluoride (CaF2) protective flat window, with a thickness of 3 mm and no coating. This window is sourced from the reputable vendor, Edmund Optics.

As a window, this optical component is designed to protect other optical elements from environmental hazards, while minimally affecting the light path. The flat design ensures a uniform, distortion-free view of the light source.

The window is made of Calcium Fluoride, a material with a high transparency in the ultraviolet, visible, and infrared spectra, making it suitable for a wide range of applications. The specific wavelength of 587.6 nm indicates its optimal performance in the green light region.

The window has a thin lens shape, which contributes to its minimal impact on the light path. The uncoated surface means it does not have any additional layers to enhance its properties or protect it from environmental factors. However, this could be beneficial depending on the specific application, as it reduces the risk of internal reflections and allows for custom coatings to be applied if necessary.

The window is currently in stock, according to the vendor's website link provided: https://www.edmundoptics.com/p/30mm-diameter-uncoated-calcium-fluoride-window/17822/. This information is subject to change, so it's recommended to check the vendor's website for the most up-to-date status.
