The MTD hyperspectral SWIR LED line lights offer a powerful and durable broadband illumination solution for spectral imaging.
Up to 14 different SWIR wavelengths are combined into a homogenous broadband spectrum, with the output power of each wavelength able to be programmed separately with irradiance levels comparable to halogen lamp solutions.
Hyperspectral MTD-LED HSL
MTD-LED HSL is a compact and flexible hyperspectral illumination unit available in different spectral variants in the range of 1000-1900nm. It offers extremely high intensity (800 W/m² at a distance of 400mm) with no significant heat emission.
The light is available in standard lengths of 300mm and 600mm with working distance options of 150mm, 300mm and 400mm focus.
Air-cooled and liquid-cooled versions with integrated temperature control are available.
Hyperspectral II MTD-LED HSL2-SWIR
The MTD-LED HSL2 line light was developed for applications that require a long illumination length, such as optical sorting in the SWIR spectral range. Different spectral versions are available in the 1000-1900nm range. An optimized reflector geometry with an enlarged aperture increases the efficiency of the focusing optics by 25%, with a line width of 14mm.
This light is available in lengths up to 3 meters. The weight of the light source is only 10kg/m and provides a working distance of 350-400mm. The lights are temperature controlled via liquid cooling.
Spectra
The following spectra are offered for the MTD-LED HSL/HSL2 line lights. In addition, customer-specific assembly variants with up to 14 different wavelengths are possible. Wavelength-specific power programming allows the spectrum to be adapted to different sensor characteristics.
Cooling / Temperature Control
Hyperspectral lights must be temperature controlled in order to stabilize the spectrum. A temperature sensor is integrated into both the MTD-LED HSL and MTD-LED HSL2, and cooling rate can be adjusted continuously using the built-in PID controller. In the air-cooled models, the speed of the integrated fans can be actively readjusted, and in the liquid-cooled version the temperature is adjusted by means of a flow regulator.
