We have developed the technology for the manufacture of the seven-component super-achromatic waveplates APSAW-7 with a wavelength range 400-1200 nm.Continue Reading
Hundreds of tactical periscopes for our defenders from russian military aggression against Ukraine. Simple and not expensive, but nevertheless fulfill their functions.Continue Reading
Trends in the development of modern sensory devices based on surface plasmon resonance (SPR) are considered. The basic principles of construction of SPR sensor are given. For excitation of surface plasmons on the surface of sensitive elements of biosensory, a prism of total internal reflection is used or a dielectric substrate are used. A thin (dozens nm) film of high-conductive metal (mainly gold or silver) is applied to the working...Continue Reading
For all ranges specified in the Specification, Optical Windows with AR-coating less than 1% on the surface are now used. For narrower ranges AR-coating is possible less than 0.5% per surface (on request).Continue Reading
General principles of wav plate manufacturing are considered. The possibility of the formation of synthetic optical anisotropy of polymethyl methacrylate (PMMA) by the method of its uniaxial stretching is investigated. The most promising is a method for manufacturing waveplates, which includes the stage of controlled stretching of the polymer material to the required phase shift value, which would generally exclude the stage of machining the plates. The general orderliness of...Continue Reading
