The 50331AU Off-Axis Replicated Parabolic Mirror is 1.50 inches in diameter, with an effective focal length of 6.00 inches, and coated with Bare Gold. These standard off-axis parabolic mirrors are circular segments from one side of a full paraboloid. The focal point is displaced from the mechanical axis, giving full access to the reflector focus area. There will be no shadowing when placing either a detector or source at the focus. The mirrors are achromatic and are offered in a wide range of working distances. Two coating options are available; protected Aluminum for UV and visible applications and bare Gold for infrared applications. The models listed are catalog versions of common OEM mirror designs.
