Precise and easy to use

The greatly compact LDM-9901 luminance estimation head encompasses a settled 1.1° estimation field point at estimation separations beginning from 0.4m to interminability. Its 5% photometric coordinating compares to the Clamor 5032 quality course B.

Measurement field aim over notch and bead sight

Estimation field centering with the LDM-9901 luminance locator head is done by point over indent and dot locate for three diverse estimation remove ranges.

Minimal scattered light

Since the LDM-9901 does not have any seeing optics interior, its inside scattered light is exceptionally negligible. It is hence well suited for estimation of moo luminance levels in estimation areas with higher climate luminance.

Traceable calibration

The calibration of the luminance responsivity is performed by Gigahertz-Optik‘s calibration research facility for optical measurands. The calibration certificate contains all the data as stipulated by the ISO 17025 details.
