The OBSCURA37 pinhole imager is an ultra-precision embodiment of the Camera Obscura effect - the Neolithic origins of imaging technology.

Combining the practicality and convenience of a rugged, cine-style PL mount camera port cover with an integrated, precision pinhole aperture OBSCURA37 produces an iconically unique image, equivalent to a 37mm focal length lens and is precision laser formed in a substrate of just 9 micometers deep.  Images have minimal distortion and vignetting, and are capable of illuminating camera sensors and film negatives over 80mm in diameter.  Close focus is as close as you can get to the front of OBSCURA37, and focus depth is infinite.
