Product Details
Description
Calcium Fluoride(CaF2) optical Crystal is widespread used in
applications of Ultraviolet(UV),Infrared(IR) and visible light,
like optical windows, optical lens and thermal imagining, it has
wide transmissive range from 0.13um(UV) to 10um(IR) and low
refractive index. Calcium Fluoride’s combination of low absorption
with a high damage threshold makes it an excellent material for use
with Excimer lasers.

Crylink
——growing crystals, linking values
We are seller of crystals. At same time, we are producer of
crystals.
It is a long and arduous process from seed crystal to the desired
single crystal, the composition of the crystal changes through
three states and eventually grows into beautiful crystals. We
witness the growth process of each crystal and clearly know
technologies of each step in the crystal growth process, which
means that we can directly provide customers with crystals that
satisfied customer requirements.
We create value. At same time, we link value.
From company to individual, we all pursue the word "value".
Individual is valuable in society, enterprise is valuable in the
industry. We cherish the existence of value. We hope to set the
enterprise’ value as start pointing, expand to the surrounding,
extend the value from the customer to the supplier. Linking
enterprise and the industry more closer, to create more value.
