Features


 
  • Possible to perform measurements in a wide absorbance range with low stray light and low noise.
    The larger the amount of transmitted light, the lower the noise of the obtained absorption spectrum so that a wider absorbance range can be measured. Measurements of high concentration samples can be performed over a wider concentration range.

  • Stable spectrometer with double beam optical system
    The light source uses a WI lamp (visible range) and a D2 lamp (ultraviolet range) that switches wavelength depending on the measurement. The double beam system divides the monochromatic light so that the diffraction grates into the control and the sample with a rotational mirror, guiding the light to the sample chamber.
    Single Monochrome Type U-3900 uses a spherical surface mirror in front of the entrance slit, while the Double Monochrome Type U-3900H uses diffraction grating.

  • UV Solutions for U-3900 (PC connected) allows for easy device control and supports various quantitative-analysis functions.
    Special operation software that offers substantial functions such as measurement data comparison and a preview function that allows for a more powerful analysis.

  • Substantial accessories for both liquid and solid measurements
    There is an abundant lineup of accessories to accommodate multiple sample and micro sample applications, etc.
 
 
 
  Loaded with aberration-corrected concave grating  
 
  • The U-3900/3900H provides aberration-corrected concave gratings with a Seya-Namioka Mount for the spectrometer.
    Both condensing and dispersing functions allow for a bright optical system, but with fewer mirrors so that light loss and aberrations are reduced.
Aberration-corrected concave grating  
 
 
  Two types of optical systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H)  
 
  • A lineup of two models with different spectrum systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H).
    The Single Monochrome is suitable for a low-concentration sample since sample light energy is stronger compared tothe Double Monochrome. The Double Monochrome is suitable for a high-concentration sample since it can measure high absorbance with little stray light.

Options


  Enhanced Large Sample Compartment Accessory
When installing this enhanced sample compartment and additional accessories in U-3900/3900H UV-VIS spectrophotometer, you can measure the reflection characteristic, polarization property caused by incidence angle and transmission of solid sample and optical component, like reflected plate.
To use 5°/45°specular reflection accessory and 10mm rectangular cell, these accessories have to be purchased separately.
