What is a double beam spectroscopy?
The double beam spectroscopy is an instrument that utilizes two beams of light instead of just one to measure light absorption during spectrophotometry. Unlike single-beam spectrophotometers, this device enables simultaneous measurement of both a sample beam and a reference beam.
What are the differences between "Hamamatsu deuterium lamps (Japan)" and "Osram tungsten lamps (Germany)" and other light sources?
A : These two companies are top giants in the global optics and lighting industry. The main differences lie in "stability" and "lifespan."
1. Hamamatsu and Osram light sources have extremely high physical stability, rejecting "data drift."
2. Hamamatsu deuterium lamps use high-purity quartz sleeves, have extremely high ultraviolet transmittance, and are not prone to blackening over long-term use, with extremely slow energy decay.
