Magnesium Fluoride (MgF2)
Magnesium Fluoride (MgF2) bụ tetragonal nti kristal birefringent, ọ bụ ihe siri ike na-eguzogide ọgwụ etching, mmebi laser, igwe na ujo ọkụ. MgF2na-enye ezigbo mgbasa ozi brọdband site na miri-UV ruo etiti infrared, nnyefe DUV na-eme ka ọ dị mma maka ojiji na ahịrị Hydrogen Lyman-alpha yana maka isi mmalite radieshon UV na ndị nnata, yana ngwa laser excimer. MgF2bụ ihe siri ike ma na-adịgide adịgide, na-eme ka ọ baa uru na gburugburu ebe nrụgide dị elu. A na-ejikarị ya n'ọhụụ igwe, microscope, na ngwa ụlọ ọrụ mmepụta ihe.
