Accurate Absorbance and Transmission Measurements, with High Sensitivity and Resolution
Visible spectrophotometer with sensitive silicon photomultiplier detector and versatile design
Overview | Specifications | Features | Gallery | Software | In the Box
The Visible Spectrophotometer combines the straightforward operation and consistent performance of a traditional spectrophotometer with higher sensitivity, faster measurement speeds, more experimental control and longer product lifetime. This system provides everything you expect from an excellent visible spectrophotometer, such as full visible wavelength range 380 – 1000 nm and impressive wavelength accuracy (<1 nm) and repeatability (<0.1 nm).
However, our system has some improvements compared to standard models. The broadband LED light source provides good spectral coverage, while delivering 10,000-hour lifetimes, minimal warm up time, requiring less frequent replacements and less failure risk than tungsten-halogen systems. Meanwhile, the sensitive SiPM detector facilitates more sensitive measurements compared to standard photodiodes.
With interchangeable sample holders, integrated adjustable slits and the ability to define parameters in software, this system offers more flexibility and versatility for your measurements than the standard plug-and-play models, without any overcomplication. Additionally, its modular design and compatible software make it easy to identify and repair or replace any components, prolonging it’s usable lifetime.
This system provides everything you need for accurate and reliable absorbance and transmission measurements, within one compact unit.
