II-VI introduces aspheric sapphire optics for high-power industrial lasers

Share this on social media:

II‐VI has introduced what it says is the industry’s first aspheric sapphire optics for next-generation laser systems that extend far beyond the 10kW range.

With industrial lasers for cutting and welding increasingly achieving output powers in excess of 10 kW, laser optics requirements are being driven to higher levels of performance and durability. 

The new aspheric sapphhire lenses have been manufactured to sub-micron optical tolerances, enabling the same advanced single-element optical designs more commonly available in fused silica, but with 20 times better heat conductivity. This greatly reduces the focal shift associated with high-power laser heating. 

The new sapphire optics will last much longer than fused silica optics at very high laser power, reducing the total cost of ownership of laser systems during their service life.

The sapphire optics are available in a wide variety of lens designs and over a broad wavelength range spanning from ultraviolet to mid-infrared.
