Light measurement photometer DSP 200

for illuminance distributionfor laboratorieswith goniometer

Ultra-fast photometer for goniophotometric measurement of spatial light distribution Class L high-performance photometer with a broad measuring range conforming to the latest standards Thanks to high-precision analog technology and state-of-the-art digital signal processing, the DSP 200 photometer from Instrument Systems sets a benchmark in terms of precision, linearity and measuring speed. Its range of uses include the measurement of - state-of-the-art test samples with pulse-width modulated LEDs and LED modules and - traditional light sources such as incandescent, halogen, fluorescent and discharge lamps. It satisfies the requirements of precision class L pursuant to DIN 5032-7 (2017) and EN 13032-1 for lab measurement of the photometric data of lamps and luminaires. A cooled silicon photodiode adapted to the brightness sensitivity of the human eye that boasts outstanding stability and precision is used as a detector. Full filtering of the photodiode reduces the influence of non-uniform illumination of the detector, parameter f9, to the technically possible minimum. This is particularly important for the accurate measurement of light sources with sharp gradients. - Precision class L according to DIN 5032-7 (2017), CIE 69, CIE 121 and EN 13032-1 - Ultra-fast goniophotometric lab measurement of illuminance and luminous intensity distribution - Broad measuring range of 0.1 mlx (display resolution) to 200 klx - Outstanding stability and lowest noise level due to detector cooling - System integration via CAN-bus and integral color display with touchscreen
