Yes, you would have to find your own mounting bracket and install it so the lens axis is accurately normal to the sensor surface. There is not a huge market in separate lenses for 1/4-inch format optical sensors, but some are sold for use with "board-level" cameras. You can also use a 1/3-inch format lens (more common) and accept a smaller field of view than the lens was designed to give (1.33x crop factor from 1/3" to 1/4").Ravenous wrote:Anyway a lens like that, which is capable of getting close enough to the sensor, is going to be very hard to find. (And hard to mount it in exactly the right place!)
Just as an example, here is a 1/3" format board-level camera, which takes a variety of lenses using a M12 x 0.5mm mount.

Here are some examples of lenses which fit such a M12x0.5 mount:

The latter link shows some $90 lenses with a resolution specified at 150 lp/mm @ 20% Contrast (on-axis).
