Gigahertz-Optik P-9710-2

Hover to zoom

The Gigahertz-Optik P-9710-2 meter used with the VL-3701 detector head can be used for the precise illuminance measurements in Lux. However, its potential is enhanced using an SRT-M37-L series front lens adapter so as to measure the luminance in cd/m². Since measurement field focusing is hereby not possible, this combination is applicable for measurements in applications such as such as light boxes.

Overview

Features

Instrument Hire models are supplied with VL-3701 detector head as standard ~ Illuminance Class A detector head (Lux) and the SRT-M37L-2 (2o) series front lens adapters to measure the luminance in cd/m².  The hire models are not supplied with any software or cables for download to PC and data recorded via the logging facility.

VL-3701 detector head

  • Photometric responsivity
  • DIN Class A parameters
  • Calibrated with broadband source at 2956 K
  • Cosine corrected field of view
  • Typical. Responsivity 0.5 nA/lx
  • 37 mm dia. x 20 mm high housing
  • 2 m coaxial cable

SRT-M37-L series front lens adapter (2 degree field-of-view)

  • Typical response : 5 pA/(cd/m²)

All Hire models come pre assembled but if the unit is taken apart simply fix the SRT-M37L lens adapter onto the VL-3701 measurement head using the SRT-M45/37 adapter. This is attached onto the measurement head using side screws. For secure fitting, the lock screws fix into the V-nut on the measurement head. The lens adapter can then be simply screwed in. The SRT-M45/37B adapter has an M6 and a (1/4”-20 BSW) tripod screw on the side for mounting to tripods and others.

 

Technical

For a detailed technical specification please refer to the instrument manual.

Important notes :

All Instrument Solutions Hire models are supplied with a an illuminance (Lux) calibration conducted prior to each rental and a copy of the manufacturers calibration at the time of manufacture for the P-9710-2 meter with VL-3701 Illuminance head and SRT-M37-L luminance lens adapter.

The P9710-2 meter is an equivalent to the P9710-1 model except it has a fixed aplifier slew rate of 20 ms in all eight gain levels.  Thus light pulses shorter than 1 ns are stretched to 20 ms. The pulse energy of the stretched pulse can then be measured precisely with the 100 µs sample rate of the optometer.
