Considering the focal length
The actual focal length, 16.5 mm, is longer than the lens focal length, f = 16 mm, by 0.5 mm.
However, if the camera installation distance of 500 mm is within the focal range (distance from
an object) of the actual lens (f = 16 mm), you can use it.
1. The focus range of the IV-S20L16 camera lens (f = 16 mm) built into the IV-S20 is from 50
mm to infinity. Therefore, the camera installation distance of 500 mm is within the focal
range, and the IV-S20L16 lens can be used.
2. When another lens (with a focal range of 16 mm) is used, if its focal range exceeds 500 mm,
install a commercially available C mount close-up shot ring. Use a ring that is 0.5 mm thick
(16.5 - 16 = 0.5 mm).

Notes
- The values shown in the tables on page 6-5 and 6-6 are only reference data for installation.
These values may vary, according to the characteristics of lenses you are using. When using
any lens, check the data using the actual equipment.
- If you want to use a camera lens other than the IV-S20L16, buy a lens with a C type lens base.
(The IV-S20L16 has a C type lens base.)
- A lens with too short focal length (f = 4.2 mm or 8 mm) will distort the edges of the field of view.
