 There are two constraints that must both be satisfied to get optimum results.  ​ There are two constraints that must both be satisfied to get optimum results.  ​

This constraint is generally not met exactly unless care is taken, but ASI's LED sources can be easily adjusted in the field to meet this condition
-  - The illuminator iris must be at the focal point of the tube lens.  This second constraint ​is guaranteed by the construction conventions of the ASI tube lenses and the length of the ''​C60-LAMP_ADPT''​.  However, the first constraint is generally not met exactly unless care is taken to be sure that it is.+  - The illuminator iris must be at the focal point of the tube lens.  This is guaranteed by the construction conventions of the ASI tube lenses and the length of the ''​C60-LAMP_ADPT''​.
