Test & Measurement

Designer and manufacturer of MTF test equipment for measuring the optical performance of lenses and cameras. In-house lens testing service offered.

Yelo designs and builds burn-in, life-test and characterization systems for probed devices such as VCSEL arrays, laser arrays, APDs, chip-on carrier devices including photonics integrated circuits (lasers, amplifiers, modulators, photodiodes, thermistors), SOAs, laser arrays, PIN photodiodes, VCSEL TO headers, miniDILs, and butterfly packages.

Offers a range of gain modules and amplifiers with ytterbium doped active tapered double clad fibers for amplification of optical pulses, both nanosecond and picosecond range.

Manufacturer of scientific imaging, microscopy, and spectroscopy solutions. Supplies innovative, flexible microscopy systems, high-performance scientific digital CCD, ICCD, EMCCD, and sCMOS cameras and spectrographs to research establishments.

Designs and manufactures custom spectroscopic systems for various spectroscopy markets including photoluminescence, Raman, UV-VIS and transient absorption. Also manufactures CO and CO2 gas lasers, terahertz gas lasers, and picosecond pulsed lasers and LEDs.

Develops, manufactures, and markets fiber-coupled laser diodes and solid-state lasers from UV to mid-infrared wavelength. Additionally we provide optical fiber cable for laser beam delivery, fiber combiner, and spectrometer.
