  NSTAS Nanosecond Transient Absorption Spectrometer is a more advanced transient absorption spectrum test system. Under the action of laser pumping, the substance produces intermediate species, and the intermediate species and concentration information can be obtained by detecting the transient absorption spectrum. Transient absorption is a necessary testing tool in the fields of chemistry, new materials and biology.

  Detection sensitivity is often one of the most important constraints in scientific exploration. The transient absorption spectrum test system uses a new type of laser plasma light source as the detection light, an optimized low-noise detector and a 12-16bit high dynamic range oscilloscope. Improve the sensitivity (detection limit) of transient absorption to more than 0.1mOD, even in the near-infrared band of 1000-1700nm, it can easily reach 0.1mOD.

  
  

  Features & advantages

  1. The test sensitivity can reach above 0.1mOD in the full range of 200-1700nm;

  2. For samples with low damage threshold, samples that are easy to be optically bleached, photoelectric functional films and other materials are excellent

    Design

  3. Built-in electric filter wheel, automatically filter light according to the test band, effectively protect the sample and reduce

    Low system stray light interference;

  4. The detection light adopts a laser plasma white light source. Hundred-micron size point light source, higher collection and concentration

    Coke efficiency, higher energy density, extremely high spatial stability and long life span of 10,000 hours;

  5. It is not limited to the conventional sample room. High-quality side detection performance, allowing more experimental environments Light path customization;

  6.4 The grating spectrometer is easier to expand and ensure system efficiency.
