1181-1 APL 1107 Resistance to fogging ocular test equipment

Back to

Resistance to fogging ocular test  equipment, laser source, heating system, set of lenses, mirrors and photo detector, including PC and software.( EN 168 , ECE 22/05)

Technical features: 

  • Frame made by 40X40 and 40X160 hard aluminium ITEM profiles;
  • Water container made by stainless steel (provided with drain plug);
  • Two lids, made by black anodized aluminium, close the sample area and the heating system area;
  • Inner ventilation system with small fan, external motor driven with belt;
  • Heating system with pump, 2 Kw installed power, precision on temperature +/- 0,1°C;
  • Adjustable sample holder, easy interchangeable.( one sample holder supplied for flat and spherical sample , other shapes available on request );
  • Mirror holder made by black anodised aluminium alloy. Sealing O-ring and clamp ring, mirror heating system (in order to avoid fogging on mirror itself) using a 25 Watts low voltage electric resistance. The power supply cables are protected and insulated;
  • Adjustable mirror holder (in order to have the laser beam vertical return) using three screws with stainless steel springs;
  • Automatic shutter, made by a nylon slide, opening the passage to the mirror, electric motor actuated;
  • Optical components;
  • Solid state 10 mW laser, with pin hole and 10X  parallel beam expander (10 mm diam.);
  • Laser square mirror 35X35 mm;
  • Beam splitter 50/50;
  • Biconvex 200mm efl lens (ES USA);
  • Silicon detector 110 sq.mm Centronics, with 10 mm diam diaphragm and beam diffuser;
  • All the component, as above described, are provided with holders;
  • Electronics devices;
  • Inside an steel and aluminium case the following components are installed;
  • Circuit driving the photoreceptor with power supply and amplifier;
  • Resistance power supply;
  • Laser power supply;
  • Smartwheel  SMD Microprocessor connected to the PC via serial port driving automatic operations;
  • Personal computer:
    • PC with Dual core 2 duo or other available CPU 2,8 Ghz (or superior), 4 Gb RAM , HD 500 Gb or superior, DVD/CD rom 56X, floppy 3,5”, 19” LCD flat colour monitor, English keyboard. (The features of PC can be changed without notice, owing to rapid hardware evolution)
    • Software
    • Original software developed by AD Engineering
    • The software is using the operative system Windows XP,Windows 7 or 8with original licence;
  • Full scale setting;
  • Maximum value with full light;
  • Minimum value without light;
  • Continuous display of the detected light in real time, , refreshing time 0,05 seconds;
  • Automatic starting of measure after the pressure of start button and after the opening of the shutter, with  programmable time via software (usually 0,5 seconds);
  • Automatic time measure : the software calculates (in real time) the time necessary to the light to be reduced to the 80% of the initial value. Precision 0,01 seconds;
  • Automatic recording of the data (stored on the HD) after each test;
  • Output in Excel format;
  • Three main languages to be selected ( English , French and Italian, German language available if the customer will supply translation );
  • Other languages  easy to be installed (original Windows version is necessary;
  • Data printing software with full samples identification;
  • Software features;
  • Extremely rapid in all the operations;
  • Extremely flexible and easy customisable;
  • Compatibility with all printers using Windows XP options;
  • Other features according to requests of EN 168 standard;
  • General features;
