PJLA-ILAC

All calibration orders are subject to the following Terms and Conditions

All precision light measurement instruments and their detectors, such as our ILT1400 and ILT1700 Light Meters, require periodic recalibration to ensure proper operation. That is why International Light Technologies has expanded our NIST traceable calibration lab and invested in new equipment.

ILT has also extended our calibration service offering to include calibration of non-ILT light measurement meters and systems (see part numbers beginning with "C" below).

Calibration Lab

As our customer base has grown over the past 40+ years, and as our customers have adopted quality manufacturing standards such as ISO17025 and ISO9001, we have seen a dramatic increase in the demand for annual NIST traceable recalibration. In response to this increase in demand for calibration services we have expanded our calibration lab, invested in new equipment, and are planning to extend our standard calibration service offering.

Annual Re-calibration

All instrumentation requires periodic re-calibration to ensure proper operation. In addition, extreme operating conditions (UV, heat, and dirt) can degrade optical performance potentially requiring an increase in re-calibration frequency. Annual re-calibration provides a relatively inexpensive guarantee of accuracy. Accurate readings translate into more efficient production processes, more reliable research and safer medical procedures.

NIST Traceable

International Light Technologies obtains fully characterized Primary Standard Detectors directly from the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Through the transfer of standards technique, we compare the output of a customer's detector to a standard under tightly controlled laboratory conditions.

ILT Calibration Lab

The list below describes the basic types of optical calibrations that we perform in our metrology lab. All instrumentation requires periodic recalibration to ensure proper operation. The PIR and YIS calibrations are our most commonly requested calibrations for radiometers and photometers, respectively. Our flexible laboratory setup allows us to perform a wide range of different calibrations at a reasonable cost.

All calibrations are performed under controlled environmental conditions.
 

All calibration and repair service orders MUST have a Return Authorization (RA) number referenced on the packaging and/or the packing list PRIOR to return shipment to ILT for service. Equipment received without a RA number will be placed on hold upon arrival pending approval for service charges. To obtain an RA number, please fill out our Return Authorization form - you will automatically receive an RA# once the form is submitted.

Please note: All calibrations are performed in the order they are received into service. Express Service orders are given priority over standard calibration orders where possible but in the event that multiple Express Service orders are in-house at the same time - Express Service orders are done in the order they were received into service. Express Service orders are subject to availability and exclude repairs and scanned calibrations. Express Service order delivery times are not guaranteed. All orders are subject to a $65 min evaluation fee. Cancelled/changed orders will be billed for any completed calibration at the time of cancellation/change, and a minimum evaluation fee of $65 if no calibrations have been performed.
