| Any other custom shape, size and focal length MgF2 lenses are available upon request. We do not have online purchasing at present so please contact us by email and order by stock code or if you do not see what you need, contact us and ask. You are assured of a friendly and direct response. |
MgF2 transmits well into the DUV / VUV region at the hydrogen Lyman-alpha line (121nm) and beyond. MgF2 windows and lenses are also used for most UV optics and is excellent for eximer laser application.
MgF2 window transmission, from DUV to IR. Sample thickness 10mm.
Magnesium Fluoride is used for optical elements in the infrared where extreme ruggerness and durability is required. The single MgF2 crystal exhibits slight birefringence through its useful transmission range and its birefringence in the infrared could be useful.
