===== Aperture =====
The opening of a lens were light travels through to the image sensor.
===== Back Focus =====

===== Iris =====
The opening of a lens were light travels through to the image sensor.
===== Optimized Achromat =====
The rear lens of the adapter that allows the image sensor of cameras, with offset images sensors, to focus on the ground glass and achieve edge to edge sharpness.\\
