CaF2-W-38.1x3 38.1 mm Dia. CaF2 Flat Window; t=3mm Uncoated

The CaF2-W-38.1x3 is a flat window type optical element with a circular base shape, sourced from Alkor Technologies. This window, designed for use in optical systems, has a diameter of 38.1 mm and a thickness of 3 mm.

The material used in the construction of this window is Calcium Fluoride (CaF2), specifically identified as "caf2 mal-1963" in the Material ID. This material is known for its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum, making it a versatile choice for various optical applications.

The window is uncoated, meaning it does not have any additional layers applied to modify its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired. However, it's important to note that uncoated surfaces can be more susceptible to contamination and damage, so handling and cleaning should be done with care.

The window is designed in the shape of a thin lens, which can be beneficial in applications where a flat, transparent surface is required, but a lens-like element is not needed. This could include uses such as protecting sensitive optical components, providing a flat surface for beam splitting or combining, or serving as a window in an enclosure.

The window is currently in stock and available for purchase, as indicated by the "weblink status" in the item data. For more information, including pricing and availability, users are encouraged to visit the vendor's website via the provided weblink.
