What type of camera were you thinking to add to the microscope ? Faveon based
chip ? 30+ megapixel regular CMOS based chip ? If the answer to both is no,
then go with the cheaper lense (achromatic). After all it is not about the
beauty of the crystals, if they diffract or not does not depend on apo- or
achromatic lenses.

Dear All,
In crystal examination stereo zoom microscopes, how important is
it if one chooses a Achromatic objective lens compared to Apochromatic
lens.
Achromatic can give higher working distance ~ 70 mm or more as
compared to Apochromatic, which may be important for picking crystals /
manipulating before flash freezing.
Is it good to compromise on working distance to get Apochromatic
objective?
An input from the community will be of great help to me.
Many thanks in advance,
Natesh.
