Newport MKS Gimbal Optic Mount, Low-distortion Axial Clamping, 4.0 in. Diameter 605-4

The 605-4 Gimbal Mount provides ultra-stable positioning of optics up to 4 inch (101.6 mm) in diameter. The pivot axes rotate 360 °, and hex-head setscrews provide coarse-adjustment lock-down for each axis. Standard AJS Fine Adjustment Screws provide ±5 ° of high-resolution fine adjustment and have tamper-proof lock screws. The pivot axes employ wobble-free, pre-loaded radial ball bearings and are spring-loaded to eliminate backlash. Adaptors provide optic registration on the gimbal axes. These mounts incorporate an especially convenient kinematic mounting design to accommodate optics of various thicknesses. The spring-loaded retaining clips have finger grip handles. Three polished steel balls kinematically register the optic surface on the gimbal axes for pure rotational motion. The retaining clips provide compressive loading opposite the balls, so the optic is not distorted. The edge of the optic rests on two steel rods. A nylon-tipped screw provides a small amount of opposing pressure for stable optic orientation. 3 in. optic adapter is sold separately. 360° Angular Range With infinite angular range in pitch and yaw, these mounts can steer a beam in almost any direction. Once the position is set, the 605 Series' fine thread adjusters can provide final alignment. 605 Series Mirror Installation With adapters, the 605 Series can accommodate easy installation of more than one mirror size. The 605-2 comes with 605A-2-1 adapter for 1 in. (25.4 mm) mirrors. The larger 605-4 can hold 3 in. (76.2 mm) mirrors with 605A-4-3 adapter which is sold separately. Both mounts feature a 3-point, low wavefront distortion mirror mounting mechanism.
