ErieOpenSpec v10

**Important** Please note:
(1) There is a small piece of diffraction grating (education grade, available on e.g., Amazon) used in the spectrometer which is not shown in the 3D model. It is placed under the viewing hole on the top panel.
(2) A newer model (A1) is currently being developed, in which a substantial modification in the light source has taken place. The newer model is expected to have a significantly higher signal-to-noise ratio.

This is an open-source spectrophotometer called ErieOpenSpec(current version v10). Parts include: (1) a 3D-printed sample holder (where an LED plate is installed) and a 3D-printed slit; (2) two laser-cut Acrylic sidewalls; (3) a laser-cut Acrylic top panel (where diffraction grating is installed); (4) a laser-cut Acrylic mirror plate (where a 1" mirror is installed); (5) a laser-cut Acrylic background plate; (6) a battery pack for powering the LED plate; (7) a cover to cut out ambient light.
