Overview

The ATP2000 Series, developed by Optosky based on years of in-depth experience in the spectrometer industry, is a cost-effective spectrometer line. After more than a decade of continuous optimization and improvement, this series offers models with high signal-to-noise ratio, high frame rates, high resolution, and low noise, all while maintaining cost-efficiency and compactness. The ATP2000 series fiber optic spectrometers are widely favored by the market and customers for their exceptional stability, catering to a wide range of applications.

Features

High cost performance

High pixel UV enhanced detector

190-1100nm wide band range

Specifications

The ATP2000 Series uses a UV-enhanced linear CMOS detector from Hamamatsu with either 2048 or 4096 pixels, capable of operating within a wavelength range of 190-1100 nm. The detector's minimum exposure time can be as short as 0.2 ms, allowing precise control over spectral measurement time for customers.

Figure 2. Dark Background and Dark Noise Test

Dark Background: 146 counts @ 1 ms; Dark Noise: ±40 @ 1 ms.

Test Method: After connecting the device, block the spectrometer’s input aperture with a screw cap to prevent external light from entering. Open the Optosky Spectra software and click "Display Settings" → "X-axis Unit" → "Wavelength" → "Integration Time (1 ms, 10 ms, 100 ms, 1 s)" → "Dark." The resulting spectrum, shown in Figure 3, indicates the dark background, calculated by subtracting the minimum value from the maximum value of the signal intensity on the Y-axis. Then, by clicking "Single Acquisition," the resulting spectrum shows the range of signal intensity on the Y-axis, which is the dark noise value.

Figure 3. Intensity Repeatability Test

Click "Display Settings" → "X-axis Unit" → "Wavelength" → "Integration Time (select the integration time that reaches 80% of full signal intensity)" → "Dark." After subtracting the dark background, illuminate with a halogen lamp to obtain the spectrum. Select six representative wavelengths from the spectrum and record them. Then, click "Display Settings" → "X-axis Unit" → "Time (set six points based on the recorded wavelengths)" → "Continuous Acquisition." After approximately 10 minutes, pause and save the data. Use the intensity repeatability calculation formula to analyze the results.

Figure 4. Response Linearity Test

Click "Display Settings" → "Number of Curves" → "Others" and select 10 curves to complete the setup. Divide 40,000 counts corresponding to the integration time into 10 equal parts, and sequentially click "Single Acquisition" to obtain spectra of varying intensities, continuing until 10 spectra are collected. Save the data and substitute it into the response linearity calculation formula. The test result is: R² = 0.9997.
