Reflex Reflector Measurement Systems
-
Photometric Solutions International Pty Ltd
The measurement setup involves using a projector to illuminate the test item, and then measuring the luminous intensity of the light reflected from the test item. The ratio of the luminous intensity emitted by the reflector (in candelas) to the illuminance on the reflector (in lux) is the coefficient of luminous intensity or CIL (cd/lx).

Monochromatic, Fiber-Coupled LED Light Sources
-
LED light sources in the LS-MC1 series provide a constantly growing selection – currently amounting to over 20 – of narrow band single wavelength LEDs with a bandwidth of 15-50 nm FWHM, allowing precise work in a defined wavelength range. As a result of optimized optical coupling into the optical fiber – as with all of our light sources – with our LS-MC1 series we have achieved the highest possible luminance. The advantage of directly emitting monochromatic LEDs is their very high level of efficiency, because the entire radiated output is in the useful wavelength range.

Photometric Probes for Illuminance
LPPHOT03… Series
-
The probe LPPHOT03 measures illuminance (lux), defined as the ratio between the luminous flux (lumen) passing through a surface and the surface area (m²). The spectral response curve of a photometric probe is similar to the human eye curve, known as standard photopic curve V(λ). The difference in spectral response between LPPHOT03 and the standard photopic curve V(λ) is calculated by means of the error f’1.

Light Sources
-
There are many low cost artificial light sources used for illumination or for industrial applications: tungsten or halogen bulbs, fluorescent lamps, LED lamps etc. Some of these sources have regulated intensity of emitted light. However, there very few calibrated light sources of precisely known parameters. A light source can be considered as calibrated when its user can precisely regulate its photometric/radiometric parameters like luminance (or illuminance), radiance (or irradiance) at defined spectrum of interest. Such light sources are needed in many applications among them, in systems for testing night vision devices, VIS-NIR cameras and SWIR imagers. Inframet offers a series of calibrated light sources that can be divides into three groups:
