We offer optical tables and optical table systems designed for precision applications in laser laboratories. Optical tables can be supplied with laminar airflow units for cleanroom environments and various vibration isolation options. For sensitive applications we offer vibration isolation systems or complete pneumatic vibration isolation workstation.Aluminium and solid steel breadboards are offered as an alternative to honeycomb table tops for smaller and non-critical optical setups. We offer a wide range of standard table top and breadbord sizes, while custom sizes can be produced on request.

DLCcoatingprice

Diamond-like-carbon (DLC) coatings are a particular area of expertise for Richter Precision Inc. Among PVD & PaCVD coating compositions and technology, DLC coatings stand out as a distinctive category. These coatings exhibit a desirable combination of a low coefficient of friction and high micro-hardness, making them extremely effective in many tribological and wear applications.

DLC films are generally amorphous (i.e have no dominant crystalline lattice structure) and consist of a mixture of sp2 (graphite) & sp3 (diamond) phases. Control of film properties is strongly dependent on the flux characteristics of the chosen deposition technique (PVD sputter or evaporation and Pa-CVD), metal and hydrogen content within the film, sp2:sp3 ratio, substrate bias voltage, ion energy and ion density as well as substrate temperature. DLC film friction coefficient against steel generally ranges from 0.05-0.20, whilst film hardness and sp3 content can be tailored for specific applications. Metal and hydrogen containing DLC (Me-DLC or a-C:H:Me) exhibit hardness in the range 500-2000HV with 35% sp3, metal free DLC (C-DLC or a-C:H) typically 1500-4000HV and up to 75% sp3 , whilst tetrahedral amorphous carbon (ta-C) can be 4000-9000HV with 80-85% sp3.

Diamond-like carbonthermal conductivity

DLC coatings are formed when ionized and decomposed carbon or hydrocarbon species land on the surface of a substrate with energy typically 10-300eV. DLC films may possess exceptional mechanical (high hardness), optical (high optical band gap), electrical (high electrical resistivity), chemical (inert) and tribological (low friction and wear coefficient) properties and can be deposited at low substrate temperatures (~200°C).
