The Computar H10Z1218MS is a 12-120mm (10x) motorized zoom lens featuring 1/2-inch image sensor format, C-mount design, motor drive iris, and neutral density (spot) filter.
The Spot Filter is a reflective type (wavelength independent), Neutral Density, radial, gradient filter. It is deposited on a glass surface that is located coplanar to the optical stop surface (at the iris blade location). The Spot Filter allows rapid light-sensitivity adjustment. Light passes thru the spot filter from the center which is fairly dark to the edges where is phases out to 100% clear. So, if the iris blades move just a little bit, you greatly impact the overall light level that passes thru the lens.
Motorized lenses can be purchased without the spot filter, but there is no price difference. Almost all of our customers want the spot filter once they understand what it does. The only times we have seen customers not want the spot filter on a motorized-iris lens is when the application is light-starved to begin with.
Computar Motorized Zoom Lenses provide remote control of focal length, iris and focus through the use of an optional lens controller, for use where variable focal length and remote control are required. They are ideal for applications requiring long distance surveillance in parking lots, highways, etc.
