A spectrometer is a scientific instrument used to analyze the interaction between light and matter. It can decompose composite light into monochromatic light of different wavelengths and record their intensity distribution.

Figure 1.Structure

The spectrometer sensor typically employs a fixed blazed grating. Light to be measured is coupled into the spectrometer through an optical fiber. After being dispersed by the grating, a CCD or CMOS sensor detects the dispersed wavelengths at individual pixel points, enabling the acquisition of the entire spectral range.

The basic components of a spectrometer sensor include a fiber connector, entrance slit, collimating mirror, grating, focusing optical system, and detector. The performance parameters and application scenarios of the spectrometer vary depending on its configuration.

01 Product Introduction

The ATP1030 is a high-resolution ultra-miniature fiber optic spectrometer developed by Optosky, leveraging over 10 years of expertise in spectrometer design. It retains the ultra-miniature features of the ATP1000 series while adopting a novel high-resolution M-type optical design and incorporating a UV-enhanced 1024-pixel linear CMOS sensor.

Compared to the ATP1010, the ATP1030 offers higher resolution. In comparison with other ATP series spectrometers, it features a higher level of integration, making it versatile for various detection applications.
