OMAC Instrumentation’s maintenance service department is adequately equipped and staffed for even a normal repair work. We undertakes any type of Optical & Precession Instruments from any sector using these Instruments & conducts Optical instrument workshops if required.
Mechanical Defects – We are specialized in catering defects of opto – mechanical angle measuring instruments, shakes, play in gears, back less, angular gear errors etc to name few and readjustment.
Old Optical Instruments develop fungus growth on a glass surface. Fungus looks like it has an appearance ofhairs or tendrils branching from a center. Even though the fungus can be removed by cleaning, it frequently has etched the glass, since fungi secrete enzymes and acids to chemically alter their environment so they can absorb nutrients. Etching process requires repolishing, which if done by a non – professional person will damage the instrument. It is not possible to detect if the glass is etched until the fungus of glass is cleaned. Optical Instrument’s maintenance involves prevention of fungus problems in the future specifically if the equipments are located in damp regions.
It is remarkable that the problem of the deterioration of optical instruments by fungi has remained so long without thorough investigation. Fungi can grow actively on or over the internal optics of binoculars, cameras, etc, exposed to warm and humid conditions. Not only were the facilities for storage of instruments extremely primitive & climatically the worst possible places for fungal troubles. The fungal infection of instruments designed for temperate regions became a major problem. The fungi which grow in optical instruments belong to the groups Phycomycetes, Ascomycetes and Fungi Imperfecti. The fungal spores germinate on the moist surface of the glass lenses or prisms or, more frequently, on particles of dust, luting wax, cork and other organic debris. The mycelium spreads thence over the whole surface of the clean optical glass. The moulds are particularly troublesome when they grow on graticules, but they are also capable of obscuring lenses and prisms. The fine hyphal threads in contact with the glass surfaces are often surrounded by minute condensed water droplets or by droplets of alkali-soluble substances liberated from the glass itself. If the mycelium remains for many months in contact with the glass, it is capable of etching a pattern into it. More commonly, when removed, the mycelium leaves only a slight stain resembling an oil film which can be removed by cerium oxide polishing.
