Mica lens thermometers such as the ETI RayTemp 38 are the most common type used in industrial settings. They have more rigid mineral-based ground lenses. This allows them to...
Mica lens thermometers often come with one or two lasers to help guide both the aiming of the thermometer and the estimation of the field of view being measured. Mica lens thermometers are the most fragile of the infrared technologies, however. They often come with carrying cases as they are more likely to crack or break when dropped. They are typically the most expensive and still need to acclimate to extreme ambient temperatures for 10 minutes or more before giving accurate readings.
