The double beam uv spectrophotometer has excellent optical performance with very low noise and stray light.
8-inch color touch screen, easy to operate
Unique deuterium and tungsten lamp (OSRAM) mounting system
Strong data processing and storage capacity
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.
