Kaleido Technology product story

On-axis, off-axis and freeform mirrors up to 700mm diameter can be produced with a surface roughness of less than 3nm RMS and a slope accuracy of better than 70urad.
Kaleido Technology has upgraded its proprietary diamond machining capabilities enabling it to produce on-axis, off-axis and freeform mirrors (up to 700mm diameter) with a surface roughness of less than 3nm RMS and a slope accuracy of better than 70urad.
In addition to large and complex ultrasmooth mirrors the geometrical freedom inherent in Kaleido's machining setup enables it to produce off-axis parts with very long working distances that cannot be done by on-axis turning.
Commenting on the advance, Dr Palle Gelzer Dinesen, Chief Sales Officer and cofounder, said: "We are seeing an immediate advantage from the two-fold improvement in achievable surface roughness for our automotive, aerospace and military customers".
"We have also seen early interest from researchers involved with X-ray and short wavelength applications where the ultrasmooth surfaces could give significant advantage".
"We are very pleased with our machining system performance after the upgrade".
"It pushes the capabilities of our cutting-edge diamond-machining capabilities even further enabling us to pursue new applications with extreme requirements", said Senior Technical Expert and cofounder Dr Christian Holme of Kaleido Technology.
"Along with our proprietary environment feedback system for extended accuracy and our proprietary machine control system including direct processing of CAD files, this accuracy upgrade really gives a technological edge in the ultraprecision optics area".
Using its ultraprecision machining centre, Kaleido Technology is able to take a CAD file directly from a customer to produce prototype and production quantity mirrors to the highest degree of accuracy and surface finish.
