This is a casing for the Macrobank system by Linos ( which is not sold any more) and for the Mikrobank system which is more popular..
Till now i had some black paper arround the optics to prevent scattering light from the outside, but with the printed casing it looks much nicer and is easyer to mount after changing somthing at the setup.
The casing is can easily be clipped at the frame of the interferometer or whatever it is..
there are two versions attached. one with the logo of our institut for technical optics (Verkleidung3) and one without. (ohnelogo3)
Length for both is 200mm
The Microbank3 file is for Linos Mikrobank system (length 50mm)
ant the Mikrobank3_with logo again with the logo on it...
For different length just resize the Y-dimension...
