Application Note: Identification of Organic and Pharmaceutical Powders

By Stanislav Perevoschikov

Real-time, in-line powder identification usually means a trade-off between speed and accuracy. We proved it doesn't have to. We recently teamed up with our Nynomic Group partner, m-u-t GmbH, to release a joint Application Note. The goal was simple: build a compact, field-ready NIR setup capable of analyzing complex organics directly in the bulk material, […]

Celebrating International Women's Day: Brilliant Minds in Photonics

By Stanislav Perevoschikov

Today, we celebrate International Women's Day by recognizing the brilliance, innovation, and courage of women who continually push the boundaries of science. The field of photonics is built upon deeply impressive contributions from female scientists. From Maria Goeppert Mayer laying the foundational work for multiphoton absorption to Donna Strickland's Nobel Prize-winning breakthroughs in laser technology, […]

Description

Hollow Silica Glass IR-Fibers (Hollow Glass Waveguides) design is a perfect option to transmit a low divergent IR-light of Mid IR-spectrum from 3 to 17μm. High performance fibers are produced with core diameters span from 500µm to 1000µm with double polymer jacket to secure a superior mechanical strength and high flexibility of HGWs.

Low optical losses at the selected spectral windows without Fresnel reflection enable a broad variety of HGW applications in Mid IR-range.
