Aluminum Reflectors

Metal or glass substrate with aluminum metallization for broadband reflection of UV, VIS and IR radiation.

Reflectors with aluminum coating represent the simplest variant of UV mirrors.
Since pure aluminum loses its excellent reflective properties in a very short time due to oxidation with atmospheric oxygen, the application of aluminum and subsequent passivation with SiO2 in a vacuum is essential.This can be applied to metals such as stainless steel or aluminum as well as to all common types of glass.

In addition to protection against atmospheric oxygen, the quartz glass layer also serves as protection against scratches and other mechanical and chemical environmental influences.
