*Depending on model

Measure precisely over a long time

A high long-term stability of the thermographic measurement with infrared camera systems of the ImageIR ® 4300  series is achieved by an excellent thermal decoupling of the electronics module which will emit heat during its operation from the optical and detector module being most important for the signal receipt.

Make use of spectral filters for material specific measurements

Material specific emissivity and transmissivity properties have to be taken into account while measuring with infrared camera systems. The integration of spectral filters makes use of those specifics for special measurements. For example, spectral ranges of thin PE foils can be excluded in case they are highly transmissive – to say transparent. Like this only the radiation will be measured which is purely emitted by the foil itself. Based on its long experience in thermography InfraTec can support you in selecting the right spectral filter. The infrared camera systems of the ImageIR ® 4300 series can integrate a remotely controllable filter wheel which can hold up to four spectral filters. The filter position close to the detector can avoid warm aperture effects and allows for the usage of smaller and thereby cheaper filters in the infrared camera.

Extend your temperature measurement range with an automatic aperture setting

The temperature measurement range of the ImageIR ® 4300 series can be widened by an integrated aperture wheel. The motorized aperture wheel can be controlled by the camera control itself. Working with calibrated measurement ranges the appropriate aperture will even be set automatically in the infrared camera. When filter and aperture wheels are separately integrated ImageIR ® 4300 will become especially flexible in handling specific thermographic measurement situations.

Easily transfer radiometric data to our computer

You can work with radiometric data both in radiation proportional format as well as directly in temperature data in °C or K. The data can easily be acquired with the handy and customizable data interface of the ImageIR ® 4300 camera series.

Focus the thermal radiation loss-free with quality lenses

In the field of thermography, low temperatures result in lower infrared radiation and thereby in smaller signal for the infrared camera. That is why all the available signal should be used. The lens is the part of the infrared camera getting in touch with the infrared radiation at first and therefore it plays an important role. Precision lenses being coated with an anti-reflection film for avoiding disturbtions take care that the whole infrared radiation will be focussed to the detector of the of the ImageIR ® 4300 series. Within this series of infrared camera systems, a wide range of lenses - starting with telephoto lenses up to microscopic lenses – can be found, too.

The high thermal resolution of 20 mK lets you detect smallest temperature differences

The thermal resolution of the ImageIR ® 4300 series allows you to measure smallest temperature differences of only 20 mK. Thermal images with a narrow temperature span display details absolutely sharp. You will find interesting signatures even there where other infrared camera systems cannot detect any temperature differences any longer.

Increase your flexibility by using the modular design concept

The ImageIR ® 4300 series is based on a modular concept and allows for successive upgrading and changes of powerful components like motorized lenses or a high-speed shutter. Already in its basic configuration it can be delivered with different detectors which support your application the best way. Like this you will always remain flexible and optimally adapt your infrared camera systems to your respective needs.
