The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples. By ...

The V-630 is an economical, general-purpose instrument with a compact design to save bench space. Its excellent spectroscopic performance is suitable for routine, QC and research applications.

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

We investigate the effect of molecular geometry and conformational flexibility on electronic coupling and charge transfer interactions within propeller-shaped perylene diimide (PDI) tetramer arrays ...

The formation of SeNPs was observed at the wavelength range of 250–300 nm by ultraviolet–visible spectroscopy (UV–vis), and their highest yield could be reached at the following conditions: volume ...

The article considers creating Laser Opto-Electronic Airspace Monitoring System in the visible and infrared ranges and its practical applications in airspace security, trajectory measurements and ...
