Chasing the right solution for UV measurement? Looking for the optimal precision in 3D light distribution data? Advanced Viso sensor solutions combined with a Viso goniometer might match your expectations.
Excellent standard solutions
The Standard sensor delivered with your Viso product will be the best choice for most applications:
The portable, price-competitive LightSpion suitcase is fitted with a STS Ocean Optics spectrometer with a Panavision ELIS-1024 spectrometer detector.
BaseSpion and LabSpion both include an Ibsen Photonics FREEDOM spectrometer with a Hamamatsu S11639-01 spectrometer detector (LabSensor and BaseSensor)
Upgrade options
Upgrading your existing labSensor or baseSensor
Previously, LabSensor and BaseSensor contained a CCD-type Sony spectrometer. However, the present Hamamatsu sensor offers several advantages. The slit size of the special Viso high sensitivity grating is 70μm (Spectral resolution < 5.0 nm). Furthermore, the sensor is 6 times more sensitive. Thus , the sensitivity range 1 meter from the sensor is impressive 0.2 – 200,000 lux <+/2.5%. Contact Viso sales for more information.

SPECIAL Measurements: UV-vis – UV-VIS-NIR – VIS-NIR
The Viso LabSensor Model2 housing and BaseSpion can be fitted with special sensors:
With one of these sensors, your Viso goniophotometer you will be able to measure visual light as well as UV and or near-infrared light in one session. Consequently, these special sensors allows for full 3D light distribution and color measurements. For UV-VIS and UV-VIS-NIR solutions, a special calibration light source is included.
Upgrade your existing LabSpion or BaseSpion with one of these sensors – or get a whole new system.

The IMPORTANT STRAYLIGHT CORRECTION
All Viso UV sensors have correction for straylight. Since UV spectrometers need high sensitivity to handle low level signals, any small straylight reflections from the spectrometer must be corrected for optimal performance. At Viso, this is done by performing a series of calibration tests at multiple wavelengths, where all straylight is recorded and stored in the calibration data. All straylight is then removed in real time from the spectrum using mathematical matrix calculations based on the straylight test data.
