Features

Narrow Design For Compact Mounting of Optical Components

SPH Series, Slim Optical Post Holders feature a smooth, narrow design of their aluminum construction, with an outer diameter of 0.75 in. (19 mm). This profile requires up to 25% less space than standard optical post holders. The space saving benefits are supported by a knob-less, hex key post clamp in a set-screw design inset within the holder.

Easy to Use Hex Clamp

A knob-less hex key post clamp that does not protrude beyond the outer diameter of the post holder and also serves as a deterrent against unwanted tampering. It uses a 5/64-in. (2 mm) hex key.

Through Hole Base Mounting

SPH Post Holders have a 1/4-20 (M6) thru hole in the base and can be attached to optical table directly or to a PHB Series open-slotted base with threaded 1/4-20 (M6) hole. These threaded bases are available in two different thicknesses to provide versatile positioning of the SPH post holders on an optical table or breadboard. 

LaserClean™ Low VOC Versions Available

Many laser-based applications require extra care to reduce volatile organic compounds (VOC) and ensure added cleanliness. VOCs and other contaminates can deposit on to optical surfaces causing degradation in output power, beam quality, and wavelength. Newport now offers certain Opto-Mechanical components that are specially prepared with clear anodize, nickel plating or stainless steel materials, special lubrication and vacuum-level cleaning. Products are packaged in Class 1000 (ISO 6) cleanroom grade bagging material and then double-bagged for further cleanliness precautions. We call these products, LaserClean™ and designate them with a -LC suffix. For more information please visit LaserClean Low VOC Optical Components Page.
