As monochromatic light source,JK300 Monochromator can make
qualitative and quantitative analysis to transparent substance and
solution as well as measuring to the apectral components of
polychromatic light source,Its application will be further extended
if necessary accessories and testing units are equipped .Inrecent
years it is widely used in physics in
physics,chmistry,metallurgy,agriculture,environmental
protection,building material and medicine departments as
indispensable testing instrument in production,scientific research
and teaching

JK300-based system can help the user with three different filter.
Filter the use of 350nm-600nm; 600nm-1000nm; 1000nm-1500nm. When
you choose to use more than 1500nm wavelength of the grating, to be
equipped with the appropriate cut-off-infrared filters.
The specific choice is as follows:
| Transmission range 300nm-2500nm |
| Transmission range 200nm-3500nm |
| |
1#filter | The use of band 350nm-600nm | ＜300nmT＜2%＞400nmT＞80% |
2#filter | | ＜540nmT＜2%＞590nmT＞80% |
3#filter | | ＜750nmT＜2%＞1000nmT＞80% |
Instruments used in the most reflective diffraction grating is
blazed grating. Blazed diffraction grating has control of its
energy in the spatial distribution of properties, it is
particularly valuable in use. I offer the following types of
companies grating:
