Microspectrometer

With integrated embossed grating – compact, powerful, versatile

Our latest development expands Eureca's spectrometer portfolio: a microspectrometer based on our PRO line scan camera, optimized for compact design and easy integration.The system utilizes a high-quality embossed grating inside, enabling reliable and precise spectral analysis.

Technical Specifications

• Safely usable spectral range: 380 to 800 nm
• Spectral resolution: 20 nm
• Light coupling: Fiber optic
• Sensor: Hamamatsu line sensor with 2048 pixels 
• Interface: USB

Main Applications

The microspectrometer is particularly suitable for analyzing broadband spectra.Typical applications include:

• Characterization of light sources
• Measurement of fluorescence signals
• Monitoring spectral changes in research and development

Open and flexible control

A particular advantage of our microspectrometers is their open and flexible control.Since the devices are based on our proven USB camera platform, they can be operated directly with all existing EasyScripts in Python.This eliminates the need for proprietary software solutions, as is common with many other microspectrometer vendors.Users receive full access to the raw data and can develop their own measurement and analysis routines.This approach is particularly valuable in teaching, as it allows students to not only interpret measurement results but also understand and design the entire data acquisition and processing process themselves.

Dual-Channel Microspectrometer

For special applications, we offer a version of the microspectrometer with two embossed gratings integrated into one sensor.This allows for simultaneous acquisition of a measurement spectrum and a reference spectrum – without the need for a second device.This design reduces systematic errors, saves space, and significantly simplifies the measurement setup.In practice, this configuration is suitable, for example, for continuously monitoring the light intensity of a source during a measurement or for compensating for fluctuations due to changes in the light source or ambient conditions.This solution also offers a clear advantage in industrial processes where both the actual signal and a stable reference must be recorded in parallel.

Embossed Gratings

The embossed grating used in the microspectrometer is manufactured by Insion GmbH, a renowned German manufacturer of miniaturized spectrometer components.Insion specializes in high-precision replication processes that emboss grating structures directly into optical substrates.This technology enables compact, mechanically stable, and optically highly efficient gratings that are ideal for use in robust, low-maintenance spectrometer systems.Thanks to their high manufacturing quality and low sensitivity to environmental influences, Insion embossed gratings contribute significantly to the long-term stability and reliability of our microspectrometers.

Available versions

Eureca also offers microspectrometers in customized versions for OEM projects, precisely tailored to the respective application. Thanks to our many years of expertise in optoelectronics, we develop systems that precisely meet your technical requirements. Possible adaptations include fiber optics in various lengths, with different connectors or special sheaths, single- or dual-channel versions, and customized electronics that fit within specified spatial constraints. Interfaces can also be designed according to your requirements – for example, USB, UART, or direct parallel control and data lines for connecting to microcontrollers. This way, you receive a microspectrometer that can be optimally integrated into your system.

Initial prototypes of various versions are already available.Later this year, the USB version of the microspectrometer, housed in a compact housing, will also be available directly from our online shop as a standalone laboratory tool for researchers, developers, and educational institutions.
