The HVM-2t is a vertical drive optic mount specifically made for thin 2-in. optics. The mount uses a threaded retaining ring to secure optics having a thickness of 6.7 mm or less. Also included with the mount is a 0.5-mm thick Delrin washer to protect the optic from damage during tightening of the retaining ring. The HVM-2t also features a rear-loading design to ensure the front face of the optic is always in the same location regardless of its thickness. The mount has standard features like a 1.5-in. optical axis height, 80-TPI hex key locking actuators, and an exceptionally thin 21-mm profile. The HVM-2t is designed with several mounting options including a center clearance hole for #8 or M4 screws, two #8 threaded mounting holes and two M4 threaded mounting holes.
Top adjust mounts have their adjustment screws located above where the optic is held so that your hands never have to cross into the beam path area.
Top adjust mirror mounts feature a slimmer profile and smaller footprint than traditional mounts. As such, they can often fit more easily into tight or restricted spaces when traditional mounts may not. Top adjust mirror mounts are ideal for use in laser cavities, OEM, and industrial applications due to their exceptionally slim profile and accessible actuators.
All of Newport's industrial top adjust mounts have locking Allen-Key adjustments to save space and prevent unintended adjustment. Among them, all aluminum mounts have a flexure lock built into the mount body, and stainless steel mounts feature a lever lock. Both types of locks exert a tangential force on the screw to prevent rotation. Adjustment and locking actions are accomplished using a single tool from the same side of the mount.
These mounts feature alignment pin holes (illustrated in red) on the bottom (base) of the mount to enable keying of the position and orientation by means of dowel pins for repeatable system integration and to prevent clocking effects. (Note: Dowel pins not included with mount.) This is especially helpful in OEM applications.
Both the HVM-05r, HVM-S1r rear load mounts and HVM-1t, HVM-S1t, HVM-2t threaded aperture mounts feature rear-loading design to ensure that the front surface of the optic would be in the same mounting location regardless of its thickness. In contrast, a front-loading mount would locate a thin optic recessed within the mount thereby limiting its reflective clear aperture.
The HVM-1t, HVM-S1t, HVM-2t top adjust threaded aperture mounts are designed to hold thin optics and lenses with a threaded retainer. They include not only a threaded retaining ring but also a protective Delrin spacer to prevent scratching the optic's coating or surface as it is secured. Vacuum pick-up tools and spanner wrench facilitate installation and removal of the optic.
