Hi! Im working on making a polarized attachment to this
for @denisedd . And figured while i was looking at a cool open science hardware project I hadn’t heard of, i might as well share it here!
Developed by Jolyon Troscianko - 2022
Released under GPL-3.0 license.
This project allows users to build their own low-cost, high-sensitivity spectroradiometer for measuring radiance/irradiance based on the Hamamatsu C12880MA chip. The spectral range of ~310 to 880nm and resoltuion of ~9nm make the OSpRad particularly well suited to visual modelling.
Testing shows that the system can measure spectral radiance down to around 0.001 cd/sqm, and irradiance down to around 0.005 lx.
Included in this project are the 3D STL files for creating your own housing, code for uploading to an arduino nano microcontroller, and a Python app for interfacing with the OSpRad spectroradiometer via desktop computer or Android smartphone (via Pydroid 3).
