Contactless Temperature Measuring
The thermal camera Workswell MEDICAS allows to measure the temperature of the human skin and is therefore effective when the body temperature increases for instance due to virus infection. The average body temperature on the skin surface of a healthy human is in the range of approximately 35.8°C to 37°C.
If the human temperature (measured on the surface) exceeds 37 °C, it may be an overheating of the body or a defensive reaction of the immune system to the infection of the organism (here the surface temperature can rise up to 4 °C, ie to 41 °C). In view of the above, it is clear that the system is not specific to coronavirus, but will generally help identify people with fever, as a result of each infection (whether relatively harmless or as severe as SARS , MERS, Ebola, bird flu etc.).
Although it is of course not possible for the infrared camera to detect infected in the non-symptomatic phase of the disease, finding people with clinical manifestations of the disease helps reduce the infection pressure in the population.
The thermal imaging camera can record temperature changes of 30 mK (0.03°C). Determining the temperature change in case of sick person (compared to a reference black body source) of 1°C is a relatively simple matter, even considering all conceivable uncertainties. For automatic detection, the ISOTHERM function can be used, which is set to a alarm temperature.
Accuracy: ± 0.3 °C

The FebriScan consists of three components: an intelligent infrared camera, a temperature reference body and a specially developed FeverScreening App. In their interplay, these components enable the body temperature to be recorded with the highest accuracy.
To guarantee the reliability of the temperature display, the FebriScan has numerous integrated fully automatic self-test functions.
This is how the test works
The detection with FebriScan complies with the IEC 80601-2-59:2017 standard. In the process the infrared camera captures the face of the person.
The temperature is measured at the most heat-intensive point on the face – namely the inner eyelid angle of the eye, which shows the actual body temperature. In combination with the high-precision temperature reference, our FeverScreening App then verifies the detection result. Only in this way is it possible to make a precise statement about body temperature.
Important: In order for the thermal imaging camera to capture the relevant area, glasses must not be worn during the measurement.
High-precision detection of elevated body temperatures according to the IEC 80601-2-59:2017 standard, automatic adjustment with temperature reference.
Integrated fully automatic self-test functions for highest reliability of temperature measurement.
3 variants for different distances between camera and face, e.g. due to local installation conditions.
Designed for 24/7 continuous operation.
Intuitive graphical display.
Thermal imaging vs. thermography
We create experiences through renderings
Even if you don't see it, there it is!
The obtaining of thermal images is a technique used to highlight the characteristics of the elements to be inspected.
Like conventional cameras operating in the visible spectrum, these devices capture electromagnetic radiation from the IR spectrum, either from the same radiation emitted by the part or reflected from illuminators operating in a specific IR band.
To the values obtained, pseudo-colour representations or data to image conversions are applied in order to process them with artificial vision techniques.
In addition to obtaining thermal images, thermography is the technique for measuring temperature from the radiometric values obtained by the acquisition devices.
The equipment is calibrated and certified in the laboratory with black calibration bodies at different operating temperatures.
The Infrared Spectrum
Making the invisible visible!
The band of the Infrared spectrum is a much wider band than the visible one, and with it different information is obtained depending on the wavelength where one works.
Conventional monochrome cameras with an increased sensitivity can capture NIR information.
Between 750 and 1400nm.
Short Wave Infrared.
Other materials in the sensors, other than silicon, are already needed for data capture, such as InGaAs.
Wavelengths between 1.4 and 3um.
Medium Wave Infrared.
They provide very extensive information and are used in applications such as gas analysis.
Wavelengths between 3 and 8um.
Long Wave Infrared.
Microbolometer sensors are used to capture this radiation, and are precisely calibrated with black bodies for accurate temperature measurement.
Wavelengths between 8 and 15um.
IR cameras are used for thermal imaging and temperature measurement by thermography.
Depending on the characteristics of the sensor, such as construction material or filters, they allow us to obtain the information of the infrared spectrum we want, from near infrared to long wave infrared.
Custom software development
Angular and distance corrections, emissivity maps, analysis by region of interest or compliance rates are only possible using powerful measurement algorithms developed and optimized for each need.
We carry out a software analysis according to the specifications and needs of the client, developing operating environments according to usability, design and features required for each application.
The data obtained and calculated are stored, in cycle, by means of an efficient database management. Traceability of images according to results obtained and history of reprocessable data.
Inspection and control of defects by means of machine vision from the information obtained from the capture equipment. Image conversions for fast processing within the most demanding cycle times.
