Cleaning IR Lenses

Sponsored by:

Always be sure to follow manufacturers instructions when cleaning infrared lenses and optics.

Lenses and optics are an integral part of any infrared imaging system. Most infrared optics are coated with special anti-reflective coatings to maximize the transmission of infrared energy to the system’s infrared detector. For imaging radiometers, each lens is individually calibrated to the imager.

Improperly cleaning a lens or coated optical element can cause the anti-reflective coating to be damaged thereby changing the transmittance of the lens and the measurement accuracy of the system. If the coating is sufficiently damaged, a costly lens replacement and system recalibration may be required. This recalibration would require sending your imager back to the manufacturer incurring up to several weeks of downtime for your imager.

Imager operation is one of the many topics covered in all Infraspection Level I training courses. For more information on our Distance Learning Program or our open enrollment classes, visit us online at Infraspection.com or call us at 609-239-4788.
