The MM-HS/MS SWIR Sensor is a lightweight, compact, and cost-effective multi-mode imager with user-selectable spectral resolutions in the short wave infrared (SWIR) band that balances image resolution with data processing time.

Data Sheet

Multi-Mode Hyperspectral/Multispectral Imager

The MM-HS/MS SWIR Sensor is a multi-mode hyperspectral/multispectral imager that allows the user to select spectral resolutions in the short wave infrared (SWIR) band – from 950nm to 1650nm.

    Key Benefits:

  • Easily switch between hyperspectral (HS) and multispectral (MS) operations
  • Has a flexible spectral range and resolution for scanning
  • Balanced between spectral image scanning speed and data processing/storage flow rate
  • light, compact, and low-cost

Multispectral imaging deals with discrete, broadband objects. It is generally used to classify objects into extended categories. On the other hand, hyperspectral imaging uses continuous spectral measurements in a narrow band. Through extensive data, it retrieves fine spectral details of objects, but at the cost of data processing time and transmission bandwidth.

KOI’s MM-HS/MS SWIR Sensor gives the best of both worlds by offering large amounts of flexibility in choosing either MS or HS measurement in a single instrument to reach the best balance between spectrum details and acquisition time. A single MM-HS/MS SWIR Sensor enables the user to take single image frames at any wavelength between 950nm and 1650nm, with the choice of a suitable spectral resolution from three enabled bandwidths – high, medium, and low. The user can also select one of the three bandwidths according to the specific time requirements of conducting a full spectral scan and acquisition. Furthermore, the user can specify the range of interest to conduct a partial spectral scan with the selected resolution.































The MM-HS/MS SWIR Sensor is equipped with a tunable filter with selectable full width half maximum (FWHM). The filter tunes from 950nm to 1650nm with a choice of three different bandwidths at each wavelength: wide, medium, and narrow. Through these filters, the MM-HS/MS SWIR Sensor can switch from multispectral imaging to hyperspectral imaging to balance acquisition speed, data volume, and data transmission bandwidth.

MM-HS/MS SWIR Sensors come with three components: the optical head, the controller, and software to run the sensor.
