Each Semrock-brand optical filter shipped by IDEX Health & Science has been inspected and found to pass the relevant cosmetic specifications, using the ANSI or ISO 10110 inspection procedure as appropriate. If the customer wishes to check if a filter meets the cosmetic specification, it is again necessary to follow the applicable cosmetic inspection procedure. To check a limited number of filters for cosmetics, an RMA can be used to return the filters to the IDEX Health & Science production facility for inspection; the results of the inspection will be shared with the customer.
