Doculus Lumus® Specifications

Doculus Lumus®

Standard Features

Doculus Lumus® has implemented 3 lights as a standard: white incident light (full and rotating, similar to coaxial light), white rotating oblique light (8 LEDs, automatic/manual rotation to the left and right for OVD and embossed printing techniques), and UV 365nm light.

15x or 22x Magnification

Doculus Lumus® is available with 15x and 22x magnification. The built-in glass lens system with achromatic, colour-true and distortion-free quality lenses allows reading of micro and also nano text already at 15 magnification.
If you are examining entire documents to see as many features as possible in a short period of time, we recommend choosing 15x magnification. If your work focuses in detail on the security features itself, their making and even the finest surface deviations, choose 22x magnification- especially if you are working away from the frontline and have enough time for a thorough analysis.

4 Extra strong UV LEDs 365 nm

The UV light, with 4 extra strong UV LEDs (365 nm), enables optimal examination of UV security colours both through the main lens and from at a short distance when lifting the device off the document. Check nanotext and various fibres on passports and banknotes. Also ideal for effortless detection of UV features on polycarbonate cards.

4 White Incident Light LEDs

White incident light enables you to check even the finest print details such as micro or nano text with 4 strong LEDs (bright field illumination). Check which printing technique was used to print a document (laser printing, inkjet, offset printing, etc.) and detect any manipulations.

The incident light can also be switched from full to single mode. In this case, only one of the 4 LEDs lights up and can be rotated clockwise/counterclockwise automatically or manually. Use it to check identigrams, holograms and OVIs (similar to coaxial light).

Since many people want to activate the light with their thumb, there is an option to switch from right-hand mode to left-hand mode. Please refer to the operating instructions to find out exactly how this works.

8 LEDs for Rotating Oblique Light

Doculus Lumus® contains 8 LEDs as a standard for automatic/manual clockwise or counterclockwise rotation of the oblique light. With the help of the 8 LEDs, which shine on the document one after the other in 45° steps, shadows are created on raised or recessed features (dark field illumination).
The oblique light enables the inspection of intaglio prints, embossings and colour-changing holograms as well as OVIs. Colour-changing elements look different depending on the angle of incidence of the light. This gives you the option of 3D-realistic detection of DOVIDs (Diffractive Optically Variable Image Device).

Torchlight Mode

Use Doculus Lumus® as a torch and to check watermarks. The torch mode allows for optimal illumination even in a very bright environment. The higher light intensity allows you to backlight watermarks and in dark environments you can use this mode as a torch substitute to illuminate close objects.

Smartphone Documentation

Click the battery cover of Doculus Lumus® into the documentation position and place your mobile phone flat on the device. No additional app is necessary for photo documentation. Simply use the camera app on your smartphone and take pictures and videos.

For easier use of the combination of Doculus Lumus® with smartphone, we recommend using the smartphone adapter (See Accessories).

Steady Light Mode for Documentation Purpose

The steady light is activated for 1 minute when the desired light function is clicked 3 times. This means that there is no need to keep a button pressed while checking a document. This mode is especially popular for photo or video documentation purposes with a smartphone or webcam.

Steady light mode is not available for the AS Anti Stokes Laser option due to safety reasons.

High Robustness

Doculus Lumus® is specially designed for outdoor use and is drop-proof from a height of 1.5 metres (tested on concrete).

The housing is water-repellent and the internal electronics are dust-protected. The lens can be kept clean with the enclosed microfibre cloth.

Left/Right Handed mode

By default, the button assignment is selected for right-handers. In most cases, left-handers want to be able to operate the incident light, UV light and torch light with their thumb. To make this possible, Doculus Lumus® is equipped with a left-handed mode!

Please refer to the operating instructions to find out exactly how this works.

Energy Source

2 AAA Batteries Lasting 3-5 Months (standard)

LI – Lithium Ion Battery
300 mAh (optional)


Using state-of-the-art mechatronics for intelligent energy saving and user safety, two patents have been approved in Austria, Germany, and the U.S.

  • The 1st patent on the electronic control ensures the constant brightness of the LEDs, even if the batteries/accumulator runs low on energy.
  • The 2nd patent refers to the automatic change of the energy supply from lithium-ion battery to the standard AAA batteries if inserted for devices with the LI option.

This ensures that the user (1) can work with the same brightness of light until the device runs out of energy and (2) that a second energy supply allows to work longer and without interruptions when out in the field.


Unter Einsatz modernster Mechatronik zur intelligenten Energieeinsparung und Sicherheit des Anwenders konnten bereits zwei Patente eingereicht werden.

  • Das 1. Patent auf die elektronische Steuerung sichert die gleichbleibende Helligkeit der LEDs, auch wenn die Batterien/der Akku leer werden.
  • Das 2. Patent bezieht sich auf den automatischen Wechsel der Energiezufuhr von Lithium-Ionen-Akku auf Standard AAA-Batterien, wenn diese eingelegt werden, bei Geräten mit der Option LI.

Dadurch wird sichergestellt, dass der Benutzer (1) mit der gleichen Lichtstärke arbeiten kann, bis dem Gerät die Energie ausgeht, und (2) dass eine zweite Energieversorgung ein längeres und unterbrechungsfreies Arbeiten im Dienst ermöglicht.
