The alignment, purity, crystallinity and surface roughness of SPL's products have all been monitored or analyzed prior to shipment and are guaranteed to be within the tolerances specified on the quotations we issue. In cases where a dispute arises over defects or inconsistencies, one of our core strengths is that we will always work with our end-customers to positively resolve the problem that is experienced, beit through a simple repolishing and realignment, or ultimately a complete replacement of the product.
