Laser Interferometers

Fabry perot interferometer or etalon is made of with two parallel highly reflecting mirrors. As function of wavelength interference between the multiple reflections of light between the two reflecting surfaces. Constructive interference occurs if the transmitted beams are in phase, and this corresponds to a high-transmission peak of the etalon. If the transmitted beams are out-of-phase, destructive interference occurs and this corresponds to a transmission minimum. This exhibits peaks and falls in transmission corresponding to resonances of wavelength. It is named after charles fabry and alfred perot.

Specifications: Fringes Spacing: 0.316 micronsIlluminations: 0.5 m W He Ne laserAperture: 75 mmPower supply: 220 V A C 50 Hz

Description: Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Rayleigh Interferometer.Specification:For measurement of refractive index of liquids & gases. The interference fringes are magnified in the instrument to over 100times by means of a cylindrical lens of the eye-piece which provides horizontal magnification. The fringes produced are sharp at the normal distance of distinct vision.It consists of following items :-a) Heavy metal platformb) Collimator with circular slit is fixed at one end.c) Telescope with cylindrical lens instead of Ramsden eyepiece is fitted on other side of the table.d) One metal box which is fitted in the front of the telescope consist of Razor Glass Plate inclined at an angle of 45 deg. This box also contains compensation plates. The whole system is connected to micrometer screw gauge to record the readings.e) Plane parallel optical glass cells for liquids.f) Pair of gas cells with plane parallel windows for the measurement of refractive index of gases.g) Vacuum pump single stage having displacement of 32 liters per minute with manometer.Supplied without sodium Lamp Unit.

Our award-winning range of XD Laser from Automated Precision Inc. (API) is a multi-dimensional laser measurement system which is used to measure angular, straightness linear, and roll errors for rapid machine tool error evaluation. These precision engineered range is fast, accurate measurement of axial capability and machine positioning makes complete machine assessment possible with up to 80% less downtime. For example, a complete measurement of a 1 meter volume machine is completed in 3 to 4 hours instead of 3 days. The XD Laser is a comprehensive wireless system with Ethernet connectivity which is available in 1, 3, 5, and 6 Degree of Freedom configurations. The 6 dimensional XD Laser is the only laser measurement system which provides simultaneous measurement of all axis errors from a single setup. The system also features the ability to evaluate acceleration, parallelism, velocity, squareness, and flatness. Features: Measurement of all error parameters from a single setup per axisCompact laser head along with base plateSingle optic squareness set-upHumidity sensor availableWireless or Ethernet connectivityControl box integrated into laser head for portabilityWeather station compensates in real time Quick alignment fixtures
