Laboratory where we can have parts checked for Thickness with a Laser Micrometer

Does anyone know of a laboratory where we can have parts checked for thickness with a laser micrometer or some other instrument that more accurate than a digital micrometer? Thanks in advance.

What "accuracy" do you need/require? Why do you determine that a laser micrometer is more accurate?

Because the micrometer we are using reads to an accuracy of 5 decimal places, with the fifth decimal place as a round up or down. So it is reading accurately only to 4 decimal places. Would like to find a lab that checks material with a laser micrometer.

Where in the US are you located, and how much are you prepared to pay for this inspection?
Are the micrometers you are using ACCURATE to 4 decimal places (0.0001" assuming you are using Imperial measurements)?
Why do you need to have a 3rd party inspection? If this has the potential of becoming a long-term issue, you would be much further ahead to investigate the purchase (or lease) of your own laser micrometer. There are a number of suppliers available which you can google search.

We are an ISO/IEC 17025:2005 accredited laboratory. When we are asked to measure a part, we normally would advise the customer which method/instrument we would reccomend to measure the requested feature.
Laser Micrometers are very good for measuring diameters. Possibly to approx. 20 µinches depending on the size of the part and brand of laser mic.

If you have a flat part, we would most likely check with a supermicrometer. We can read to 1µinch with an accuracy of 5-10µinches.
