Stainless steel water container equipped with a drain plug.
Two black anodized aluminium lids enclosing the sample area and the heating system zone.
Internal ventilation system featuring a compact electric fan.
Heating system with integrated pump, 2 kW installed power, and temperature accuracy of ±0.1 °C.
Adjustable and easily interchangeable sample holder (one holder supplied for flat and spherical samples; custom shapes available upon request).
Mirror holder made of black anodized aluminium alloy, complete with sealing O-ring and clamping ring; mirror heating system powered by a 25 W low-voltage electrical resistance to prevent condensation. Power supply cables are fully protected and insulated.
Adjustable mirror holder with three stainless steel spring-loaded screws to ensure precise vertical return of the laser beam.
Motorized automatic shutter with a nylon slide to open/close the optical path to the mirror.

5 mW solid-state red laser (635 nm) with pinhole and 10× parallel beam expander (10 mm diameter).
35×35 mm square laser mirror.
50/50 beam splitter.
Biconvex lens with 200 mm Effective Focal Length (EFL), manufactured by ES USA.
Silicon detector with integrated electronic driving circuit, 50 mm² active area, 10 mm diameter diaphragm, and beam diffuser.
All components listed above are supplied with dedicated mounting holders.
Electronic devices
The following components are housed inside a robust steel and aluminium enclosure:
- Photoreceptor drive circuit with integrated power supply and amplifier.
- Power supply for the heating elements/resistances.
- Laser power supply module.
- Optical QUASM 7 Microprocessor connected to the PC via USB/Ethernet port for automatic operations control.
- Personal computer.
- 15.5” HP laptop PC pre-installed with dedicated proprietary software.
Software
- Original proprietary software developed by AD/GTM/QI.
- Compatible with Windows 11. (Nota: Rimosso “Full-scale setting” da qui poiché fa parte dei punti successivi).
- Full-scale setting capabilities:
- Maximum value calibration under full light.
- Minimum value calibration without light.
- Continuous real-time display of detected light intensity with a 0.05-second refresh rate.
- Automatic test start and shutter opening upon pressing the “Start” button, with a programmable delay (typically 0.5 seconds).
- Automatic duration measurement: the software calculates in real time the time required for light intensity to decrease to 80% of its initial value (accuracy: ±0.01 seconds).
- Automatic data logging to the hard disk after each test cycle.
- Data export in Excel format.
- Multi-language interface selection: English, French, and Italian are standard (German available upon customer-provided translation).
- Additional languages can be easily integrated (requires a standard Windows OS version).
- Report printing module with comprehensive sample identification data.
Software features
- High-speed processing across all operations.
- Highly flexible and easily customizable architecture. Compatible with all Windows-supported printers. (Nota: Ho sostituito Windows XP con un più generico ed attuale “Windows” dato che sopra si cita già Windows 11).
- Additional features available to meet specific requirements of the EN 168 standard.
