1.0 in. Post Spacers offer precise tuning of mounting height to 1.0 in. optical posts and pedestals, which provide highly stable mounting of optics at their fixed incremental heights. The PS series spacer has a clearance hole suitable for 8-32 or M4 screws centered in the solid stainless steel body while PS-T series spacer features 1/4-20 (M6) clearance hole. Both series offer a wide range of custom heights in increments as small as 1/32nd of an inch (.79 mm). Other sizes offered are 1/16th in. (1.6 mm), 0.125 in. (3.2 mm), and 0.25 in. (6.35 mm). 

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.
