  • General Purpose Integrating Spheres

    Edmund Optics Inc.

    General Purpose Integrating Sphere Systems are designed to spatially integrate radiant flux in order to measure optical radiation. The spheres can be coupled with a sensor to create radiometers, photometers, or spectroradiometers in order to measure the total geometric flux emanating from a light source or the flux density of an illuminated area. Additionally, these sphere systems can be used to measure the output of high power lasers and laser diodes or to measure the reflectance and transmittance of materials.

  • Light Meters

    Edmund Optics Inc.

    Light Meters are used to measure the light output of an illumination source for a number of optical applications. Light Meters are measurement devices that feature photodiodes to determine the level of light transmitted from a source. Light Meters possess simple, easy to read screens upon which measurements are displayed in one or more photometric units. Most Light Meters possess traceable NIST certification for proof of accuracy.

  • Dual Axis Galvanometer Optical Scanners

    Edmund Optics Inc.

    Dual Axis Galvanometer Optical Scanners provide superior positioning speed and accuracy precision than comparable compact, cost-sensitive, closed loop galvanometers. Featuring low inertias, compact sizes, and high speeds and accuracies, these galvos are ideal for applications including biomedical systems, optical coherence tomography, laser projection, confocal microscopy, and analytical instrumentation.

  • Detectors

    Edmund Optics Inc.

    Detectors are used to measure the illumination of a light source for a number of optical or spectrometry applications. Detectors consist of arrays of photodiodes or photodetectors that transmit electrical current when excited by collision from photons. Detectors enable the measurement of important light characteristics that are not conveniently acquired in other ways. A selection of photodiodes is also available with linked amplifier capabilities for easier, more precise measurement capacities.Detectors

  • Avalanche Photodiodes

    Edmund Optics Inc.

    These avalanche photodiodes (APDs) are silicon photodiodes with an internal gain mechanism. As with a conventional photodiode, absorption of incident photons creates electron-hole pairs. A high reverse bias voltage creates a strong internal electric field, which accelerates the electrons through the silicon crystal lattice and produces secondary electrons by impact ionization. The resulting electron avalanche can produce gain factors up to several hundred.

  • Optical Chopper

    Edmund Optics Inc.

    These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.

  • Amplifiers

    Edmund Optics Inc.

    Amplifiers are used to amplify the energy output of photodetectors as well as convert their electrical signal for a number of illumination measurement or spectroscopy applications. Amplifiers are digital systems that amplify the low electrical current transmitted by photodetectors to easily detectable levels. Amplifiers also convert photodetectors' electrical current into voltage so that their signal may be read by other digital devices. Amplifiers are indispensable for nearly any light measurement applications by greatly increasing the usability of a detector system.

  • Spectroscopy

    Edmund Optics Inc.

    Spectrometers are used to measure the properties of light for a variety of applications including environmental or chemical analysis, fluorescence, or Raman. Spectrometers are optical instruments that can detect spectral lines and measure their wavelength or intensity. Spectrometers are ideal for determining compositional makeup for detecting weak light signals. Spectrometers can also be used to test the efficiency of an optical filter in order to determine whether a filter has properly blocked or transmitted specific wavelengths.

  • Prisms

    Edmund Optics Inc.

    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.

  • Silicon Detectors

    Edmund Optics Inc.

    Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have some amount of current that is not representative of incident light. For example, fluctuations in thermal energy can easily be mistaken for light intensity changes. A variety of these "non-light" contributions are present and, when summed up, make up the total noise within the detector.
