Hamamatsu Maico MEMS Confocal Unit Confocal

Hamamatsu Maico MEMS Confocal Unit Confocal

MAICO MEMS confocal unit is a confocal unit easily installed on your inverted microscope to achieve confocal fluorescence imaging. This compact, bench-top unit, does not require other devices such as cameras, filters or lasers. As an entry-level model, or as a sub-model of a high-end confocal fluorescence microscope, MAICO makes confocal fluorescence imaging more accessible.

  • Our modular subunit structure makes adding extra channels easy
  • MAICO has a unique subunit structure which contains all the necessary components for each fluorescence band excitation and detection in a single unit.
  • By adopting the subunit structure you can, for example, select a single fluorescence band when you purchase your first unit. You can then add more imaging channels as your research progresses. In addition, MAICO’s elegant design allows on-site installation of subunit, therefore avoiding disruption to your research.
  • MAICO supports single channel observation as well as up to four multi-channel (405 nm, 488 nm, 561 nm, and 638 nm) simultaneous excitation and observation.
  • High-sensitivity detectors
  • Hamamatsu Photonics’ detectors have a long track record in the field of fluorescence measurement.
  • By adopting the world’s most sensitive detector (photomultiplier tube) and applying our signal processing know-how, we were able to reduce the laser power to a Class 3R with sufficient fluorescence signals.
  • This has important implications for live cell imaging, such as long time-lapse imaging.
  • High-speed scanning with MEMS mirror
  • We adopted our 29 kHz resonant type high-speed MEMS mirror as a spot scanning device. The MEMS mirror allows for a high-speed scan up to 76 frames/s and can be used for high-speed phenomena such as Ca2+ dynamics.
  • The high-speed resonant scanning system reduces laser irradiation time, which enables low phototoxicity, low photobleaching and high-efficiency observation of live cells as well as fixed samples.
  • High-speed scanning allows for comfortable observation at high resolution with minimal display delay when searching for and focusing on samples.
  • Conventional confocal optics
  • MAICO was designed to comply to the conventional confocal optics, which has a long history, using a spot scanning device and pinholes to acquire optical sectioning images.
  • When imaging thick fluorescence samples, only the fluorescence emitted from the focal plane of the objective passes through the pinholes to the detector, while fluorescence emitted from further away from the focal plane is blocked.
  • It detects quantitative, reproducible and reliable signals. It also acquires high contrast images without the need for image processing techniques, such as deconvolution.
  • No laser control area required
  • As MAICO utilizes our most sensitive detectors and signal processing know-how, we were able to successfully reduce the laser power to a Class 3R. Therefore, you can use MAICO in a normal laboratory environment, without the need for a laser controlled area
  • Software support
  • MAICO is compatible with DCAM-API®, a common camera library, and can be controlled by Hamamatsu’s HCImage software. It is also possible to acquire images with DCAM-API compatible third party software.
