A microlens array used in a spectrograph. A microlens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometres (μm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to optical diffraction at the small features.
“If you set a bar too high, you may fail, so it’s better to set smaller goals to achieve it,” Hafeez said. “Nothing starts without an honest conversation with yourself.” 3.
This means the lens's F-number value is fixed to the overall designed focal ratio of the optical system (the diameter of the primary mirror divided into the focal length). The inability to stop down the lens results in the catadioptric lens having a short depth of field.
