Are the lenses water soluble?

A. The injection moulded plastic lens material is not water soluble. The windows employing these lenses are very durable and have an IP65 rating. Some common lens materials, however, such as Calcium Fluoride (CaF2), Magnesium Fluoride (MgF2), and Barium Fluoride (BaF2) are soluble in water and may diminish or lose their ability to transmit infrared radiation in a moist environment. (see our materials pages).
