VL-3701 with SRT-M37-L

Illuminance and luminance measurement 

The VL-3701 is a detector for precise illuminance measurements in Lux. Its application potential can be enhanced using an SRT-M37-L series front lens adapters so as to measure the luminance in cd/m². Since measurement field focusing is hereby not possible, this combination is mostly applicable for extensive illumination fields e.g. light boxes. 

Easy set-up 

In order to fix the SRT-M37L lens adapter onto the VL-3701 measurement head, the SRT-M45/37 adapter is required. 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. 

1° to 5° Field-of-View angle 

Lens adapters with 1°, 2°, and 5° FOV angles are hereby offered. 

Traceable calibrations 

Luminance responsivity calibration can be performed by Gigahertz-Optik‘s calibration laboratory for optical measurands. Calibration is validated by a calibration certificate.
