Hemispherical light transmission measurement

Used for:

Measuring the light transmission in clear materials used in greenhouses.

Conforms to:

NEN 2675:2018 Greenhouse glass - Determination of optical properties of greenhouse covering materials and screens

Principle of operation:

Insert the pane to be measured in the machine.

The Admesy glass transmission system is a fully enclosed suspended gonio system containing a system enclosure made from high-end Item® profiles and panels to ensure system closure, block external light and shield the user from moving parts.

The suspended gonio system has four axis suspended gonio movement to move the light bundle in accordance with standard or programmed angles. It contains a broad wavelength LED with collimating lens system to ensure accurate stable lighting and an automated glass mount to load and position the glass sample during testing. An integrating sphere ensures uniform measurement results, while an integrated reference light corrects for in-system glass reflections.
 

Technical characteristics:

• Fully enclosed 4-axis gonio lighting
• High uniformity full spectrum Lightsource
• Automated glass sample mount
• High-end Neo spectroradiometer
• Easy to use operating software
• Full data logging
