The ultimate production interferometer for Multi-fiber (and Single-fiber) ferrule end-face geometry measurements.

Based on the design and philosophy which made the DAISI a success, here is the brand new DAISI-MT White-Light / Red-Light interferometer, dedicated to the measurement of end-face geometry of multi-fiber ferrules (single-fiber capability).

Its revolutionary design makes it ideal for the use in the production environment as well as field applications.
Non-compressed, real time and high quality images are transferred from the hardware to the software via USB high speed links at speeds up to 100 images per second in addition to the automation and control commands.
DAISI-MT is portable and can be interfaced to laptop or desktop computers.
All calibration steps are automated and embedded into a user-friendly software interface in order to yield error-free and reliable measurements.

Software for DAISI-MT was redesigned from ground up with many automation features and a sophisticated interface to the microncontroller-based electronic interface of the system.


 

Mechanics and electronics

White-Light interferometers’ mechanical and electronic design is more challenging than Red-Light (monochromatic) interferometer’s design. The whole optical system must be translated over several dozens of microns with nanometric precision and in a perfectly linear fashion.
DAISI-MT system does just that: based on a 30 microns stroke closed-loop piezoelectric transducer, the focus is smoothly, precisely and quickly scanned across the sample surface in less than 10 seconds.
