Photo of the NIRSpec prototype demonstration model with its protective cover in place. This is what the integrated flight instrument will look like.
The NIRSpec demonstration model is mechanically representative of the flight instrument, but only the pick-off mirror and foreoptics are optically functional and a near-infrared detector array has been placed in the position of the micro-shutter array.
