1. A measuring cell for performing optical measurements of at least one measured variable of a medium disposed in the measuring cell or flowing through the measuring cell, the measuring cell comprising:
a first recess extending through a first outer wall of the measuring cell and/or a second recess extending through a second outer wall of the measuring cell opposite the first outer wall; and
one or two window mounts, each including a transparent window, wherein the window mount, at least one of the window mounts or each window mount, respectively:
comprises a predetermined number of at least two distinct, radially outwardly protruding projections distributed around an outer lateral perimeter of the respective window mount; and
is configured to be inserted or is inserted into a respective recess of the first and/or second recess assigned to the respective window mount at an installation depth selectable from at least two different installation depths,
wherein a wall of the measuring cell surrounding the respective recess on all sides includes a set of contact surfaces for each one of the selectable installation depths, formed in an exterior face of the wall, wherein:
each set of contact surfaces includes a corresponding contact surface for each one of the projections; and
the contact surfaces of each set of contact surfaces are distributed around a longitudinal axis of a respective recess of the first and/or second recesses and are each arranged at an axial height along the longitudinal axis of the respective recess such that the window mount is insertable in the respective recess to a selected installation depth when its projections are aligned with the contact surfaces corresponding to the selected installation depth and each projection rests on one of the contact surfaces of the set of contact surfaces for the selected installation depth.
