Spectrophotometer U-3900/3900H
 

 

Research grade UV Vis spectrophotometers featuring traditional double beam technology, PMT detector and variable band pass down to 0.1nm
The U3900 / 3900H offer a wide linear dynamic range and features a double monochromator for exceptional stray light rejection.

 

   
 
    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.

 

    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.
