Doculus Lumus® Use Cases

15x or 22x Magnification

15x or 22x magnification with high quality glass lens system.

If you have to scan whole documents to see as many features as possible in minimum time, you would prefer 15x magnification.

22x magnification allows you to see finest details, but the area of sight is smaller due to the necessary lens construction.
If you have to go into detail and would like to see things like paper fibers, printing artefacts and even finest deviations of the surface, you would prefer 22x – especially when you are in the office and have enough time for a deep analysis.
Do you need a chinese 60x magnification to check optaglio elements? No! 22x Doculus Lumus® is sufficient.

  • The pictures were taken with Doculus Lumus® 15x and 22x and a smartphone to show the different field of view. This happened without zooming to show the difference as good as possible – when you take a picture combining your device and a smartphone you can additionally use the digital zoom of your smartphone to see more details.
  • Please note: digital zoom never replaces an optical lens system!

4 Extra strong UV LEDs 365 nm

The UV light mode with its 4 extra strong UV LEDs (365 nm) allows an optimal depiction of UV security inks through the lens as well as from the side from short distance.

Check nanotext and several fibers on passports and bank notes. Also ideal for effortless detecting of UV features on polycarbonate cards.

You can use your Doculus Lumus® also as a small UV torchlight so you don’t need an extra torchlight.

4 White Incident Light LEDs

White incident light with 4 strong LEDs (bright field illumination) allows you to check even the finest printed details like microtext or nanotext.

Recognize with which printing technology a document was printed. (laserprint, inkjet, offset, etc.).

Many people want to activate the incident light with their thumbs, so there is the possibility to switch from right hand mode to left hand mode. How this works exactly, can be found in the user manual.

8 LEDs for Rotating Oblique Light

8 LEDs for automatic or manually rotating oblique light to the left or right. The oblique light mode allows you to identify intaglios, embossing and colour changing kinegrams or holograms. With the aid of 8 LEDs that successively shine on the document in 45° steps, shadows are created at heightened or deepened features (dark field illumination). Colour changing elements look different depending on the angle of light incidence. So you have the possibility of a 3D realistic detection of various sublime security features and holograms.

You can also detect injured paper fibers (especially with 22x magnification) or distinguish real from printed signatures.

Steady Light Mode for Documentation Purpose

The steady light function is very useful if you want to take a snapshot through the lens with your cell phone or smartphone camera or you do not want to keep the button pressed with your finger.
Click the battery cover to the documentation position and you can lay your mobile phone flat on the Doculus Lumus®.

There is no extra app necessary for photo documentation. Simply use the camera application on your smartphone.

Torchlight Mode

In certain situations, e.g. at bright sunshine, the normal incident light mode may be too dark. You will need a higher light intensity to shine through water marks as well. The torchlight mode allows an optimal illumination even in a very bright surrounding. In dark environment use this mode as a torch replacement for illuminating close objects.

Front UV Torch (optional)

The Front UV Torch with an extra strong 365 nm UV LED in the front of the device allows a quick and easy check of UV security inks and fibres from a distance and to view an entire passport page at a glance.

RFID-Transponder Quick Check (optional)

The RFID transponder check allows verifying of the transponders that are integrated in passports or ID cards. Therefore you can check authenticity, proper function and transponder type in a very short time. Please keep in mind that in some passports a shielding prevents reading from outside. Just open the document to check it from the inside.

The RFID transponder check applies to all RFID transponder types worldwide (e.g. Type A / Type B).

IR Laser 980 nm (optional)

For the Anti-Stokes effect, named after the physicist Sir George Gabriel Stokes, printed fluorescent particles of rare earths are irradiated with a strong light source with higher wavelength. The laser is used for this purpose with invisible infrared radiation in the near range at 980 nm. The particles emit radiation in the range of lower wavelengths, so there is a shift into the visible range. Most of the particles shine yellow or green, but other colour shades are also possible.

IR LED 870 nm (optional)

The IR LED with a center wavelength of 870 nm is perfectly suited to display IR security features in the 830 to 925 nm range. Since wavelengths in the infrared range are invisible to the human eye, an additional camera sensor is needed for visualization. For this, we recommend using a smartphone, a commercially available camera or webcam to take a picture through the lens. Depending on the camera sensor, the image is colourless or has a pink tint. If the latter is the case, simply switch to black and white view of your smartphone for easier recognition (see chapter Photo Documentation Mode).

Note: Your camera system cannot be equipped with an infrared filter to use this option. (Not possible with iPhone models including and older than iPhone 7 / 7 Plus, excluding iPhone SE

Li-Ion Battery 300 mAh/Battery Change Mode (optional)

This is an integrated pre-loaded Li-Ion battery with 300 mAh. The device can operate with the Li-ion battery and also alternately with two AAA/LR03 batteries with 1.5 volts each. The Li-Ion battery can be used until it is empty. Afterwards  standard AAA batteries can be used as long as the Li-Ion battery can be charged.

Ultra Low Energy Consumption

One set of batteries (2 pcs. AAA) lasts for 3 – 5 months.
If battery is low, the red LED blinks three time slowly after releasing a button.
The device turns off after 1 minute to save energy (if a button is pressed inadvertently or the steady light function has been activated e.g. in a case).

Option: Operating with Li-Ion battery

High Robustness

Doculus Lumus® is specially designed for outdoor use.

Whether it falls down or you hit it somewhere, Doculus Lumus® can handle it! The housing is water-rebellent but not waterproof. Please also don’t drown it into coffee (sugar has a conductive effect).

There was a user, who accidentally drove by car over it, even our Doculus Lumus® has endured that – but we recommend not to try this at home!
