DF-660 full spectrum OES

 

Introduction

 

1) Czerny-Turner optical system is applied for a better plane CCD collection for all elemental wavelength that falls into 130-800nm.

2) Self-developed DF-IV collection device is able to collect all elemental wavelength between 130nm and 800nm.

3) Several matrices can be analyzed such as Fe, Cu, Ai, Zn, Ni, Sn, Ti, etc.

4) Module design for independent light collection, data processing and data optimization. with the help of high-performance ARM processor and real-time operational system, analytical time is largely shortened and accuracy is further improved.

5) 3G thermostatic system improves the energy efficiency to a great extent. The temperature fluctuation range of ±0.2℃ makes the DF-400 perform more stable.

6) the DF II-S digital-controlled light source increases the elemental analytical range and accuracy.

7) Plane grating allows smaller number of CCD, further improving the accuracy and stability. It also occupies smaller space and makes set-up and movement a lot easier.

8) the multipurpose operational software can meet various needs by displaying elemental data in a flexible way and supporting various printing formats.
