Monarch II - Mobile Multispectral Camera

Unispectral’s Monarch II- the world’s smallest portable tunable hyperspectral IR camera for agriculture, industrial, scientific, and commercial use.

The Monarch II allows you to capture in-field/on-site spectral images easily and inexpensively. No need for expensive, bulky and sensitive equipment, that require a trained operator and are blind to scene context. Its affordability and simplicity remove the barrier to wide adoption in many applications and mass-market platforms.
Monarch II opens a wide array of new applications for any industry segment.

Main features:

  • High speed lens
  • 60 FpS on monoband mode, 25 FpS on dual band mode
  • Windows and Android power and operation interface
  • Hyperspectral filter
  • 705nm-920nm Spectral range
  • Only 60x40x14.5mm, 30gr

Re-designed based on many field tests, PoC’s and commercial implementation feedback, Monarch II, its analytic software, and user interface allow the quick integration into your domain, right out of the box.

Handheld applications


Whether in field, on the road or in lab, Monarch II is ready for use through a USB-C connection to an Android mobile device. All the camera controls, settings and output display are provided through an android application. Immediate analysis and decision making is possible through the AI application that provides diagnostics of produce, merchandise, humans, medical processes etc.

Embedded / fixed applications


Monarch II can be embedded in sorting robotics, machine vision platforms, manufacturing lines, QA systems and biometric authentication terminals. It can also connect to real-time analysis, inspection and control systems through a PC interface. The camera controls, settings and output display are provided through a Windows application. Analysis and decision making can be made immediately, either by the operator or algorithm.


By capturing multiple spectral images in near-IR bands, Monarch II extracts a layer of actionable information for immediate inspection, detection, and classification applications. Monarch II small and light camera captures and immediately produces multiple single-band [± 2.5nm] spectral-cube images within 680nm-940nm spectral range.

Analytics Software

Monarch II can be ordered with the “perClass™”* PC analytic application that will allow you to extract just any underlaying information from the images you just took. Whether it is sorting, diagnosing or detecting; your specific professional knowledge and experience is easily integrated and registered into the system algorithm, to highlight through false color display the subtle grayscale reflection differences of hyperspectral images. This feature transforms the Monarch II into a powerful, real-time decision-making system.

Unispectral provides full documentation including DLL and SDK for the development of industry dedicated analytics and automation software. Solutions can also be designed and developed by Unispectral and its partners upon request.

* Unispectral teamed up with perClass™ to enable real-time analysis to connect Monarch II to any windows-based platform. The application controls the camera and analyzes in real time the acquired spectral cubes to enable the automatic or manual decision process.
