How does a Hamamatsu mini spectrometer work?
Technology
Mini spectrometers are advanced instruments integrating Hamamatsu’s MOEMS (micro-opto-electro-mechanical-systems) technology, which combines optical technology, semiconductor devices, optical systems, and MEMS technology with circuitry and software. At the heart of these mini spectrometers is a proven Hamamatsu image sensor, widely used in analytical and measurement applications. Hamamatsu also develops its own gratings, allowing mini spectrometers to feature various specifications, including high resolution, wide spectral range, and high diffraction efficiency in the ultraviolet region.
Configuration
The functions of the main components in mini spectrometers are outlined below:
- Entrance Slit: This opening transmits the measured light, with the aperture size affecting optical properties like spectral resolution and bandwidth. Light input methods include optical fiber input and surrounding light.
- Collimating Lens/Mirror: This lens collimates light passing through the entrance slit and directs it onto the diffraction grating, which then splits the light into different wavelengths, allowing each wavelength to pass through or be reflected at a different angle.
- Converging Lens/Mirror: This component focuses the light scattered by the grating onto the linearly arranged pixels of the image sensor, creating an image based on wavelength.
- Image Sensor: The image sensor converts the optical signals into electrical signals, which are then outputted for analysis.
Mini spectrometers leverage these components and technologies to offer a compact, efficient, and cost-effective solution for a wide range of analytical applications.
Monochromators and polychromators are key spectrometric devices. While monochromators have an exit slit installed along the focal plane of the converging lens or mirror, polychromators are designed for simultaneous detection of multiple spectra. Mini spectrometers are compact polychromators, incorporating a linear image sensor at the focal plane of the lens or mirror. To ensure portability and compactness, mini spectrometers have shorter focal lengths for both the collimating lens or mirror and the focusing lens or mirror compared to traditional monochromator
