ILLUMINANCE / IRRADIANCE

Probes to measure illuminance or irradiance

The use of specialized probes is necessary for a variety of distinct optical qualities and measuring geometries. As a full-line manufacturer, we provide a range of optical probes with varying spectral ranges, degrees of cosine correction, and types of optic fibers for photometric and radiometric studies.
All of our spectrometers come with irradiance and illuminance probes, which are made specifically for each system based on the optical performance and spectral range of the device.

Ready-set-go

Measurement probes, fiber optic cables, and adapters for specialized spectrometers are all included in each full package. includes calibration that can be linked to national labs.

Smart detection

A sophisticated detection system included in every GL Optic Spectrometer recognizes a new probe and installs the relevant calibration file automatically.

Made for everyday use

Excessive performance and precision no longer equate to excessive complexity. Without requiring highly skilled personnel, our solutions produce dependable, repeatable results.

GL OPTI PROBE 1.1.10 Illuminance Usage

Submersible probe for measuring irradiance and brightness underwater. The kit comes with a GL SPECTIS 1.0 series spectrometer adaptor with a coder, polymer fiber optics, and a measuring probe. The only range in which the set can be spectrally calibrated is over 400 nm. N.A. equals 0.22.
The GL OPTI PROBE calculates optical quantities of illuminance [lx] or PAR energy [W/m2], which represent the amount of light flux incident upon a surface per unit area.

GL OPTI PROBE 5.1.10 Illuminance Usage

For measurements of extended spectral irradiance, an irradiance/illuminance diffuser with quartz glass fiber optics is utilized. The kit comes with a quartz fiber optic adapter, a measuring probe, and a coder for spectrometers in the GL SPECTIS 1.0 series. Within the spectrometer’s working range, this probe spans the entire spectral range, from UV to IR. N.A. is 0.20.

GL OPTI PROBE 5.1.50 Illuminance Usage

For measurements of extended spectral irradiance, an irradiance/illuminance diffuser with quartz glass fiber optics is utilized. The kit comes with a quartz fiber optic adapter, a measuring probe, and a coder for spectrometers that are GL SPECTIS 5.0, 6.0, and 8.0 compatible. Within the limitations of the spectrometer being utilized, this probe spans the entire spectral range, from UV to IR. N.A. is 0.20.
