    Edmund Optics offers a wide range of Optical Prisms in a variety of designs, substrates, or coating options. Designs include Right Angle, Amici, Penta, Schmidt, Wedge, Anamorphic, Equilateral, Dove, or Rhomboid prisms, in addition to Corner Cube Retroreflectors or Light Pipe Homogenizing Rods. Anti-reflection coatings include MgF2, UV-VIS, UV-AR, VIS 0°, VIS-NIR, or multiple laser line options.

  • Pyroelectric Detectors

    Laser Components IG, Inc.

    Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.

  • Rotation Luminaire Goniophotometer

    LSG-1800 - Lisun Electronics Inc.

    LSG-1800/LSG-1700 Goniophotometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The LSG-1800 is an update version for LSG-1700, the LSG-1800 use a high accuracy Motor and precision angle coder which keeps high test accuracy. It is for industrial laboratory measurements the photometric data of luminaries such as LED luminaries, HID lamps, fluorescent lamps and so on.

  • Sensors For Positioning

    Leuze electronic GmbH + Co. KG

    With moving system parts that need to automatically work together, the positioning of parts or work pieces with millimeter accuracy is of great importance. We offer devices here with two operating principles. One is a laser distance measurement device that measures against a reflector and the other is a bar code positioning system that has a red light laser which determines the position and speed relative to a bar code tape.

  • Spectral Sensor

    AS7264N - AMS Technologies AG

    XYZ Chromatic Color and 440/490nm Blue Sensor with Electronic Shutter. The AS7264N provides direct XYZ sensor data which conforms to the tri-stimulus standard observer color response of the human eye. In addition, two channels added for measurement of blue spectrum light, plus a near-IR channel enables additional application flexibility. LED drivers with programmable currents are provided for electronic shutter applications.

  • Stroboscope

    KM 2239 B / KM 2240 - KUSAM-MECO

    Stroboscope is a flash - frequency velocity measuring device. It is a rotation speed measuring device that makes use of persistence of vision (when the light source synchronize with the rotation speed of an object at a pre-set flashing frequency, a relatively static phenomenon called visual persistence will occur).In the course of observation of an object that rotates or moves at a high speed ,adjust the flashing frequency of the device to synchronize it with rotation or movement speed of the object. .

  • Towing Dynamometer

    RS-25K - Taylor Dynamometer, Inc.

    RS-25K Towing Dynamometer is designed fortesting today’s full-sized SUVs and light trucks. The RS-25K is builtwith a heavy-duty steel frame, an aerodynamic body and rides on anindependent, air ride suspension using two eddy current absorberswith special high temperature coils to absorb energy. The RS-25K ispowered by an industrial generator so there are no lead-acid batteriesto charge and testing time is unlimited at low speeds.

  • Turbidimeters

    GAO Tek Inc.

    Turbidimeters are instruments used for measuring the turbidity of liquid substances. Turbidity is the optical properties of a liquid that causes the intensity of light rays to decrease. Turbidimeters assess the degree of this turbidity, which is an indicator of the environmental health of the liquid. This measurement is carried out in wavelengths in a cell with modifiable constant temperature. GAOTek turbidity meters are imperative tools for monitoring water quality and are for sale to the United States, Canada and globally.
