Optical and Mechanical Mounting Considerations
3.4.1. Using a C-Mount Lens
For the best results, the use of a C-mount lens that matches the optical format of the
sensor’s imaging area is
recommended (refer to the sensor specifications starting at Chapter 5). For more information on Thorlabs C-
Mount lenses, please visit www.thorlabs.com.
C-mount lenses are specified with a flange focal distance of 17.5 mm in free air. However, there can be
considerable variation in the flange focal distance among commercially available lenses, as well as effects due to
inline optics.
To accommodate for these variations the camera has a fixed flange distance of 18.0 mm to allow you to bring
objects at infinity in focus
before
the infinity stop on the lens is reached.
3.4.2. Mounting the Camera
On most commercial microscopes, the use of a suitable adapter is recommended in order to match the optical
format of the imaging area. Please note that some commercial 1X adapters may under fill the imaging area, leading
to vignetting of the image.
Six 1/4"-20 tapped holes are provided, one or two on each side of the housing. These may be used with tripods or
other optical mounting devices. These 1/4"-20 tapped holes are compatible with Thorlabs Ø1" posts. For more
