The MF-W-25.4x4 is a flat window type optical element, sourced from Alkor Technologies, with a diameter of 25.4 mm and a thickness of 4 mm. This window is designed in a circular base shape, following the 'Thin Lens' shape concept.
The material used in this window is Magnesium Fluoride (MgF2), identified as 'magnes dod-1984-n-o' in the material database. This material is well-known for its excellent optical properties, including a high transmission rate and resistance to environmental factors.
The window is uncoated, meaning it does not have any additional layers of material applied to enhance or alter its optical properties. This can be beneficial in certain applications where a natural optical path is desired.
