Raman Laser Spectrometer Kit with Arduino Mega
Build a Precision Raman Laser Spectrometer with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
From material science research to undergraduate capstone projects, the ability to capture Raman spectra opens a window into molecular structure. This kit guides you through constructing a 532nm laser spectrometer built around the AS7265x 18-channel sensor and an Arduino Mega, turning scattered light into actionable spectral data. You'll set up the optical path with a notch filter, align the laser, handle noise with discrete capacitors, and log results to SD card — all on a stable optical rail.
What You'll Build
You will construct a self-contained Raman spectrometer that excites a sample with a 532nm laser, isolates the Stokes-scattered signal with a notch filter, and reads the spectrum across 18 wavelength channels via the AS7265x sensor. The built system displays real-time spectra on a 2.4-inch TFT, timestamps data with the DS3231 RTC, and stores it on a MicroSD card — a functional instrument for materials identification, chemical analysis, or advanced maker exploration.
What You'll Learn
- Align a laser, notch filter, and sensor on an optical rail for Raman signal collection
- Interface the AS7265x 18-channel spectral sensor with Arduino Mega over I2C
- Implement noise filtering with 100nF capacitors and 4.7kΩ resistors for clean readings
- Log time-stamped spectral data to SD card and visualize it on a TFT display

Who This Kit Is For
This kit is designed for final-year B.Tech students in ECE, EEE, or Engineering Physics, M.Sc. and Ph.D. scholars building custom lab tools, and participants in the Smart India Hackathon tackling spectroscopy challenges. It also fits advanced ATL Tinkering Labs at IITs, NITs, VIT, BITS, and IISc — anywhere hands-on Raman instrument building is part of the curriculum or research.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to start the AI companion for step-by-step diagnostics of your exact setup, and reach us on WhatsApp for additional live troubleshooting if a sensor or alignment isn't cooperating.
Can I use this spectrometer for quantitative analysis?
Yes — the AS7265x provides calibrated spectral response across 18 channels, and with proper baseline correction you can correlate peak intensities to concentration. The kit includes the noise-handling components required for repeatable readings.
Do I need any additional lab equipment to run the project?
Only a USB power source for the Arduino and sample vials or substrates to hold your test materials. The optical rail, laser, and filter are all pre-selected to work together, so no extra alignment tools are required.
What kind of samples can I test with this kit?
Transparent liquids, thin solid films, and powders placed directly in the laser path. It works well with organic compounds, polymers, and inorganic materials that produce a measurable Raman shift under 532nm excitation — ideal for classroom demos and material identification projects.
