fiber optic spectrometer

Adopting imported high-performance grating/200-1100nm full spectrum/modularity/good thermal stability

CME-FS2000 is a lightweight miniature spectrometer that provides high-speed spectral acquisition and has a signal-to-noise ratio (SNR). Adopting CT type structural design, with a wavelength range of 200-1100nm, standardized SMA905 fiber interface, miniaturized volume, and stable structure. Support secondary development on Windows, Mac, and Linux platforms, and can be customized according to customers' requirements for optical resolution and luminous flux

Widely used in various fields, such as transmittance and reflectance measurement, irradiance, absorbance and concentration measurement, color measurement, concentration measurement of chemical composition or radiometric analysis, film thickness measurement, gas composition analysis, protein, biological research and other fields.

Product advantages:

1. The wavelength range can be selected from 200nm to 1100nm, and the slit can be selected from 5um-250um;

2. Adopting CT non cross symmetric optical path effectively reduces stray light and improves system resolution;

3. It can achieve a collection speed of 1ms;

4. Smaller and thinner size, more convenient to integrate into devices;

5. High anti reflective cylindrical mirror, stronger signal;

6. Rich optional accessories, including light source, fiber optic, and CCD probe;

7. No need for external power supply, USB direct power supply plug and play interface, stable operation;

8. Improve electronic design with 16 bit high-speed A/D conversion for fast data acquisition;

9. Integrate the GPIO interface of Zhongke Weineng, making it convenient for users to obtain data through USB, serial port, and SPI;

10. Provide a secondary development toolkit that encapsulates all functions, with one addition and multiple calls.
