Brand new in original Newport packaging. Never put into use, these were spares. Includes original hardware kit.
The SL-A 15ABD Gimbal Optical Mount facilitates fast, accurate positioning of large 6.0 inch (152.4 mm) circular or rectangular optics. Unlimited rotation in elevation and azimuth allow the mount and optic to be oriented in any position in space. Circular optics smaller than the mount’s nominal diameter are securely held inside the mount ring by extendible clamp arms. Circular and rectangular optics larger than the nominal diameter may also be attached to the mounting ring with external clamps. For added versatility, a large aperture in the base allows light to pass through unobstructed. A clutch nut on each axis allows the mirror to be quickly oriented in any coarse position. Locking the clutch nuts enables up to ±1.05° fine adjustment with differential micrometers.
Unlimited rotation in pitch and yaw (elevation and azimuth) allow the mount and optic to be oriented in any position in space with true gimbal motion.
3 in. (76.2 mm) diameter mirrors can be easily installed into SL8A mounts without the need for adapters. This also applies to 6 in. (152.4 mm) mirrors for SL15A mounts and 8 in. (203.2 mm) mirrors for SL20A mounts. We have some SL8A mounts available for sale separately in our webstore.
SL-A Series mounts include 3 clamp arm adapters that can be attached to the mirror holder so that it may hold optics smaller than the mount's nominal diameter.
