Magnesium Fluoride Lenses

  • Introduction

Magnesium Fluoride Lenses

CVD magnesium fluoride (MgF2-CVD) has good mechanical properties, chemical stability, impact resistance, great anti thermal fluctuations and radiation. While it has excellent transmission from 0.11 to 9 um, suitable for optical lenses, wedge, and window manufacturing. MgF2 is also considered as durable material in deep UV and LWIR applications.

Hyperion Optics offers custom parameter MgF2 lenses; we strictly control the alignment of C-Axis to avoid birefringence effects during usage. Please talk to our technicians of further information.
