PD-9304

Modular detector

Some photometric application areas require measurement devices whose application potential is as flexible and diverse as possible. Through the PD-9304, Gigahertz-Optik offers a Si-photodiode detector for Laser power which can be modified for photometric and radiometric measurements using its exchangeable filters. 

Si-photodiode detector 

The high quality Si-photodiode of the PD-9304 has a 1cm² large photosensitive surface. Its spectral responsivity is calibrated in 10nm steps from 400 to 1100nm. This detector is thus ideal for measurement of monochromatic Radiation e.g. very low power Lasers . 

Photometric detector 

With the PD-93-VL exchangeable filters and the PD-93-COS diffuser window, the PD-9304 can be modified to form a photometric detector. The V(λ) matching of the luminous flux measurement head generally corresponds to the DIN-5032-T7 quality class B. Calibrations are also optionally offered. 

Radiometric module detector 

With the PD-93-RW exchangeable filter, the PD-9304 can be modified to form a radiometric detector for the spectral range between 400 and 1100nm. Calibrations are also optionally offered. 

Use with all optometers 

The detector can be combined with all optometers and light meters from Gigahertz-Optik. 

Traceable calibration 

The PD-9304 module detector can be calibrated in terms of its absolute spectral responsivity of the photodiode as well as the absolute illuminance and radiometric responsivity and relative spectral responsivity of the photodiode with add-on filter. Calibrations are performed by the Gigahertz-Optik calibration laboratory for optical radiation measurands. The calibrations are documented in an individually compiled calibration certificate. The design and contents of the calibration certificate are in accordance with the ISO 17025 specifications.
