Product Description

Magnesium Fluoride (MgF2) Infrared Optics

Product Overview

Magnesium Fluoride (MgF2) optical components offer exceptional transmission performance from UV to infrared wavelengths. With high transmittance from 200nm to 700nm, these windows and lenses provide superior water resistance compared to similar fluoride materials, making them ideal for demanding optical systems where durability is critical.
