OPCF-40C03-P 40 mm Dia. CaF2 Round Flat Window; t=3 mm Uncoated

The OPCF-40C03-P is a 40 mm diameter Calcium Fluoride (CaF2) round flat window, featuring a thickness of 3 mm and uncoated. This optical window is sourced from OptoSigma, a reputable vendor known for its extensive catalog of high-quality optical components.

This window is categorized as a flat window, designed with a base shape of a circle. The geometry of this item includes a diameter of 40 mm and a thickness of 3 mm, making it suitable for various applications that require a transparent and robust optical barrier.

The material of this window is identified as "caf2 mal-1963", which is a specific type of Calcium Fluoride. This material is widely used in optical systems due to its excellent transparency in both ultraviolet and infrared regions of the spectrum. The uncoated nature of this window means it does not have any additional layers applied to its surface, which can affect its optical properties.

The wavelength specified for this window is 588 nm, which falls within the visible light spectrum. However, due to the wide transparency range of CaF2, this window can be used in systems operating at other wavelengths, including ultraviolet and infrared.

The window is shaped as a thin lens, indicating that it has been precisely manufactured to maintain optical quality. This makes it suitable for use in imaging systems, laser applications, and other optical setups where maintaining high optical quality is crucial.
