Precision non-contact infrared thermometer uses fiber optics.

The Opticon/Argosy Series is available with a special attachment for aiming light for precise sighting and a refocusing attachment for small spot sizes.

The Opticon/Argosy Series is said to provide the user with a low cost and reliable way to read temperature by non-contact means. This precision non-contact infrared thermometer Infrared thermometers measure temperature using blackbody radiation (generally infrared) emitted from objects. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers  is said to offer the latest advances in fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber  technology with ease of set-up and performance.

Fiber optics cable is available either as single strand, flexible bundles or rigid rods, transmitting infrared energy from the measured point to the sensor head. They are used in applications in which it is difficult to secure an unobstructed view of the target, or when the sensor probe must be located in an environment too hostile or too confining for the normal optical head.

An Opticon system consists of four elements, including the electronic signal processor, the detector sensing head, a fiber cable which can terminate in a high temperature rod and a fixed or focusable lens to give the desired spot size at the desired distance.

The basic Opticon head contains an aiming light and an infrared detector An infrared detector is a photodetector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic.

The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena.

 fiber bundle (1) A set of adjacent optical fibers running in parallel and adhered together. It is used for transmitting light to brighten an area as well as transmitting whole images, but not for digital communications.

(2) A collection of optical fibers.
, The aiming light transmits visible light down one branch of the bundle while infrared is transmitted up the other branch to the detector. Focusing assemblies are available.
