Metalized sapphire windows are created by applying thin layers of chrome, nickel and gold around the edge of a sapphire window. This metalized edge creates a surface that can be soldered or bonded directly into your opto-mechanical assembly allowing you to create a hermetic seal. Hermetically sealed optics is used in a variety of applications ranging from infrared imaging systems to medical devices. Technical capability Material: optical sapphire (Al2O3) Diameter tolerance: +0, -0.1mm Thickness tolerance: +/-0.05mm Clear aperture: 90% Surface quality: 80-50 scratches and digs Surface accuracy: 2 lambdas per 25.4mm @ 632.8nm Parallelism: < 3 minutes Coating: AR coating, T > 98% @ 1260-1600nm Metalizing: Chrome, Nickel, and Gold; sputtering method or screen printing method

Electricity Lab is a versatile training kit for a laboratory. It is designed such that all the basic electrical circuits can be tested with the help of this trainer kit. The experiments given with training system develop mental starting from an introduction to the circuit, basic fundamentals and experiments on Ohm's Law, Magnetism, Relay, Power, Lenz's Law, Motors, Diode, Kirchoff's Law, R, L, C and many more. This simple training lab provides a strong foundation for future studies in electrical or electronics. This takes students from the basic of ohm's law, through simple series and parallel circuit analysis and into same elementary aspects of electronics where they will build circuits using capacitors and diodes. With this system a set of coils and cores are provided. These high quality coils (Labeled with number of turns) and laminated iron cores provides an effective introduction to electromagnetic theory.
