Surface Preparation Laboratory
Surface Preparation Laboratory - SPL - is specialized in creating well prepared and well characterized single crystal surfaces. Our primary specialization is in single crystals of elemental metals, metal alloys and of oxides. We select the highest quality materials and provide high-precision crystallographic orientation combined with the best surface finish. For the precision orientation and polishing of oxide single crystals, we also work in close cooperation with Surfacenet, who are the best we know in the world of oxides. SPL and Surfacenet share the same philosophy about quality and service.


We have worked in the field of crystal and surface preparation since 1984 and are very aware of the needs and wants of this scientific community. On April 1, 1999, René Koper set up SPL as an independent company that provides the scientific community with the high-quality crystal and alloy surfaces it requires.

Surface Preparation Laboratory offers no "standard" products. All SPL's products are tailor made. SPL makes every effort to ensure its clients get precisely what they want. So, René Koper encourages his customers to formulate their demands as explicitly as possible, via the "request quotation form". This enables René Koper to produce the best product, provide optimal service, and give the professional advice that you have every right to expect.
