This is a system for an optical spectrograph. A prototype is actually working but not yet fully documentated here. It is also not planned to put the first design, which is a wooden box with prism, entrance slit and linear CCD here. Instead a new design consisting of a 3D printed case shall be given.

The sensor is actually a ILX554B linear CCD, but as Sony stoped the production it will be later replaced by a different sensor. The CCD is read by an ATMega8 microprocessor. Using an serial interface it is connected to a computer (USB to serial interfaces do work). A Java program utilizes the RXTX package to connect to the device.

Main components are:

1. Board to connect linear CCD - not yet posted here

2. Board with ATMega 8 - not yet posted here

3. C programm for the ATMega 8 - posted here

4. Java programm on the computer - posted here

5. Case for the linear CCD - not yet posted here

6. Case for a prism - not yet posted here

7. Case for a slit and lensing - not yet posted here
