Precision CS Lens Adapter

Wed Jan 21, 2015 1:48 pm

Here's a link to information about our new Proto Armour CS Lens Adapter Kit:

Proto Armour CS Lens Adapter Kit

Proto Armour for Raspberry Pi and Camera enclosures require an internally mounted Raspberry Pi camera module. The camera module includes an integrated fixed-focus lens that works well for most general applications. When performance of the stock lens is not adequate, or the need arises for a macro, wide-angle or telephoto lens, an externally mounted lens can be used. The Proto Armour CS Lens Adapter Kit adds a CS-lens mount to all Proto Armour for Raspberry Pi and Camera enclosures.

A CS-mount lens includes a male thread which mates with the female thread on the adapter. The thread on the lens is nominally 1.000" (25.4 mm) in diameter with 32 threads per inch, and is designated as '1-32 UN 2A'. The thread on the adapter is also nominally 1.000" (25.4 mm) in diameter with 32 threads per inch, but is designated as '1-32 UN 2B'. The distance between the adapter's lens mounting flange and the camera module's image sensor plane is 12.526 mm (sensor mounted in Proto Armour enclosure). This distance is called the flange focal distance (FFD). The standardized FFD and thread specifications allow the use of interchangeable lenses that have a 'CS' designation. A C-mount lens can also be used with the Proto Armour CS Lens Adapter Kit, but because the FFD of a C-mount lens is 17.526 mm, a 5 mm spacer ring must be used to make up the difference.

Removal of the Stock Lens is Required

Removal of the stock lens from the Raspberry Pi camera module is required when using the Proto Armour CS Lens Adapter Kit. This modification must be done with extreme caution as the module can become permanently damaged as a result of not using the proper tools or without attention to static control. Instructions are included in the kit, and the process requires the lens removal feature integrated in all Proto Armour for Raspberry Pi and Camera enclosures shipped after August 2014.

This kit includes hardware necessary to attach a CS lens to the following enclosure kits:
