Fiber Optics

3D Optical Surface Profilers are white light interferometer systems, offering fast, non-contact, high-precision 3D metrology of surface features.

Laser crystals, nonlinear crystals and optical crystals, as well as high precision optics, including windows, lenses, prisms, mirrors, filters, waveplates, etc.

Photometric quantities include: luminous flux – in lumens (lm), luminous intensity (lm/sr), illuminance (lm/m²) and luminance (lm/m²sr).

• Luminous Flux Measurements (in units of lumens) are performed with a luminous flux meter. This type of testing is typically used for characterizing the total output of sources such as: LEDs, Lamps and Fiber-Optic Illuminators
• Illuminance Measurements (in units of lux) are performed with a lux meter. This involves the measurement of the amount of luminous flux incident upon a surface, per unit area. Such measurements are important in the following fields: Architectural and Medical
• Luminous Intensity Measurements (in units of candela) are performed with an instrument that may be described as a luminous intensity meter or a candela meter. This type of testing is typically used for characterizing the output of a relatively small source in a particular direction. Typical devices under test include: LEDs, Automobile Headlamps and Signal Lamps
• Luminance Measurements (in units of nits, or candela per square meter) are performed with a luminance meter. This involves measuring the light emitted in a particular direction by a given spot on the surface of a relatively large, or extended source. Typical devices under test include: Computer Monitors, Television Screens, Avionics Displays and other Electronic Displays
