High precision laser galvanometer mirror reflector

Cambridge Technology, a subsidiary of Novanta, UKThere are two main categories of high-precision laser galvanometer mirrors: silicon based mirrors and more expensive beryllium based mirrors

Silicon based reflector mirror：

The outstanding advantages of silicon based mirrors are maintaining excellent optical performance, lens rigidity, good thermal conductivity, and dynamic performance close to beryllium mirrors at low cost. Can adapt to most customer applications and accept OEM customized orders.

Beryllium based reflector:

Beryllium is ranked fourth on the periodic table (hydrogen helium lithium beryllium), with the first two hydrogen and helium only existing in a gaseous state at room temperature, and the third lithium or lithium alloy spontaneously igniting in air due to its high activity. In this way, beryllium, ranked fourth, has become the lightest known practical metal material with high stiffness and stability. This outstanding feature determines that beryllium based mirrors are the choice for lightweight and ultra high speed laser galvanometer mirrors.

It is precisely for this reason that,Cambridge TechnologyThe CRS series of ultra high speed resonant scanning laser galvanometers uses beryllium based mirrors throughout the entire line.

For OEM customers who pursue scanning speed,Cambridge TechnologyAcceptable customized orders for beryllium mirrors.

Note: Pure beryllium metal has certain biological toxicity,Cambridge TechnologyThe company has the ability to process and handle beryllium metal through ISO14001 certification, ensuring that the beryllium metal reflector does not pose any health risks to the operator during use. If you need to scrap the scanner with built-in beryllium substrate reflector for any reason, please do not dispose of it at will and contact the manufacturer for advice on disposal methods.

Beryllium based reflective mirrors with slotted or honeycomb structures ensure high mechanical rigidity while being lightweight
