The Value of a Coherent Calibration

When you send your meter or sensor back for service, Coherent provides much more than just a calibration.

Many of our meters and sensors service items include both calibration and minor repairs. This means that in addition to calibration we replace damaged components and recertify the product as able to perform to the same specifications as when it was new.  In addition, eligible products receive an extended 12 month warranty following recertification. This is the same 12 month warranty we offer on a brand new product.

A large percentage of our calibrations are performed within five business days, and expedited service is available, to minimize our customer’s downtime.

Calibration of a Coherent power and energy laser measurement product includes:

  • Calibration to original uncertainty levels
  • Minor repairs (see note below)
  • Extended 12 month warranty, on eligible products
  • Fast calibration turn around time.

Minor repairs includes fixing manufacturer’s defects, hardware updates, firmware, software updates, damaged connectors, and other small repairs. Detector element replacement due to laser damage and damage caused by negligent use is not covered – for customer caused damaged an additional repair service charge is applied.

This level of service results in an overall lower cost of ownership for our customers. Those customers who routinely send products in for annual calibration are realizing a lifetime warranty for their products.

By choosing Coherent you are choosing a company you can rely on for fast delivery, low warranty rate, and lower overall cost of ownership.

Recertify Once a Year 

Coherent laser power and energy meters are precision instruments, capable of delivering very accurate measurements as well as providing many years of useful service. To maintain this high level of performance, and to ensure compliance with your quality and ISO certification, it is important to have your measurement system serviced and recertified once per year.

Extended use of laser power and energy meters and sensors, as well as environmental factors, can have an adverse effect on accuracy and also result in wear and/or damage to parts critical to optimum performance.

How long will it take?

After receiving the item to be serviced and following customer approval to proceed with the work, we are typically able to ship your product back within five working days. Some products take longer, and many products are turned around faster than this. Expedited service, including 24-hour service, is available for an additional charge.

RMA - Instructions for Returning Equipment for Repair and Calibration

To prepare your instrument meter or sensor for return to Coherent, make a tag that includes the name and address of the owner, the contact individual, the serial number, and the RMA number you received from Coherent Customer Service. Attach this tag to the unit.

Wrap the product with polyethylene sheeting or equivalent material. If the original packing material and carton are not available, use a corrugated cardboard shipping carton with inside dimensions at least 6 in. (15 cm) taller, wider, and deeper than the product. The shipping carton must be constructed of cardboard with a minimum 375 lbs. (170 kg) test strength. Cushion the instrument unit in the shipping carton with packing material or urethane foam on all sides between the carton and the instrument or probe sensor. Allow 3 in. (7.5 cm) clearance on all sides, top, and bottom. Seal the shipping carton with shipping tape or an industrial stapler.
