Product Description

Polished Magnesium Fluoride (MgF2) optical Window

MgF2 (Magesium Flouride is transparent over a extremely wide range of wavelengths .windows, lenses ,and prisms made of this materials can be used over the entire range of wavelengths from 0.12μm(vacuum ultraviolet ) to 8.0μm (infrared). High quality synthetic VUV grade MgF2 is quite expensive. Low grade MgF2 is sometimes used in the infrared but it is inferior to CaF2. MgF2 is tough and works and polishes well, but it is slightly birefringent and should be cut with the optic axis perpendicular to the plane of the window or lens.

Transmission Range 0.11 - 7.5 µ
Crystal Structure Tin oxide
Cleavage Plane Parellel to A or C axis
Colour colourless
Density 3.1766 (18°)
Melting Point (°) 1255
Reflection Loss 4.8% (visible) for 2 surfaces
Solubility index 0.0076gm/100gm water / 18°C
Hardness (Knoop) 415kg/mm2
Thermal Conductivity (cal/cm sec°C) 0.3W (m K) at (13°C)
Thermal Expansion coefficient (/°C) 18.8x10-6(Parellel to C axis)
1.31x10-6(Vertical to C axis)
