Copper mirror

Copper mirrors are made from OFHC copper, an electrolytically refined metal

Our copper mirrors are made from OFHC copper, an electrolytically refined metal. This is particularly pure due to its production process and has an oxygen content of less than 0.001%. A copper mirror is therefore more ductile and has a higher conductivity. Optical mirrors made from this material are typically diamond-machined and are flat, spherical or toric in shape. You can therefore choose from a wide range of product variants. Of course, we also offer high-quality optical mirrors as customized individual products. However, large and small series production is also part of our wide range of services. Copper mirrors are used as total reflectors for laser cutting and offer maximum reflection with excellent cooling options with active or passive water cooling.

General

OFHC/OFE copper is a metal with a high heat capacity and is ideally suited for high-power laser applications.

OFHC = Oxygen-Free High Conductivity.

OFE = Oxygen-Free Electrical.
