MANUAL (PDF) | Quantum thermal imagers. Questions

(Thermal imagers Quantum XD&XQ) Colour palettes

Colour palettes

Quantum offers a choice of 7 color palettes for captured by objective lens image, monochrome (usual “hot white”, “hot black”) and color highlighting the hottest and coldest areas with different colors.

(Thermal imagers Quantum XD&XQ) Rangefinding reticle

Rangefinding reticle

Quantum has a stadiametric rangefinder performed in the shape of rangefinding reticle which enables distance measuring to observed objects with known height (deer - 1,7m; boar – 0,7m; hare – 0,3m) with a sufficient precision.

(Thermal imagers Quantum XD&HQ) High image frequency

High image frequency

Due to the high image frequency (50 Hz) it is comfortable to use thermal camera dynamically (during rapid moving of observer or object of observation).

(Thermal imagers Quantum XD&XQ) Operating modes

Operating modes

The Quantum suggests three operating modes, each designed to deliver best possible image in specific viewing conditions. The modes are as follows: “City” (enhanced contrast), “Forest” (low contrast) and “Identification” (improved rendering of hot objects’ details).

(Thermal imagers Quantum XQ) Quick start-up time

Quick start-up time

The Quantum thermal scopes feature short start-up time (2 seconds) from the push of a button to full operational status. This is one of the best results in its class.    

(Thermal imagers Quantum XD&XQ) Display OFF

Display OFF

When it is necessary to temporarily stop observation the user can apply DISPLAY OFF function. It provides the necessary level of camouflage (no light from the eyepiece of the device) between observation sessions as well as the fast restart of observation (when display is turned off, all other systems are working; for normal operation it is enough just to power on the display again).

(Thermal imagers Quantum XD&XQ) Power saving mode

Power saving mode

Disabling the video output module in the Quantum thermal scopes increases self-contained operating time on a set of batteries or external power supply.

(Thermal imagers Quantum XD&XQ) Calibration


The Quantum suggests three calibration modes: silent manual mode (“M”), automatic (“A”) and semiautomatic (“H”). The “A” mode implies calibration without user participation (process initiation (actuation of the shutter) takes place automatically). In the “H” mode the user decides on his own if calibration is required based on the image quality. Button “Cal” is pressed in this mode. Manual calibration (“M”) is carried out by pressing the button when the lens cap is closed. The “M” mode is recommended for hunting due to silent operation.

(Thermal imagers Quantum XD/XQ) Body


The body of fiberglass reinforced plastic is able to effectively withstand impact, moisture and dust which allows the units to be used in extreme conditions. The rubber armouring ensures secure grip of the unit.

(Thermal imagers Quantum XQ) Wireless remote control

Wireless remote control

The wireless remote control allows basic operations (On/Off, Calibration, Digital Zoom) to be fulfilled without resorting to standard controls.

(Thermal imagers Quantum XD&XQ) Wide range of operating temperatures

Wide range of operating temperatures

Quantum imaging scopes are effective for the use in low temperatures (-25°C) thanks to the frost-resistant OLED display employed in the unit (image remains the same as when viewing at positive environment temperature).

(Thermal imagers) Brightness and contrast control

Brightness and contrast control

The control wheel located next to the lens allows the user to setup brightness and contrast most appropriate for specific situation.  

(Thermal imagers) Self-contained power supply

Self-contained power supply

The Quantum is powered with four AA size (rechargeable) batteries. The batteries are stored in a container which is then placed in a battery compartment of the unit.      

(Thermal imagers) Video output

Video output

All Quantum models are equipped with an analog video output to enable connection of external recording equipment or transmitting image to the display.

(Thermal imagers) External power supply

External power supply

Operation time of the unit can be significantly increased thanks to the use of external power supplies (for example, Pulsar EPS3/EPS5) that can be connected with a special jack. When used in frosty weather, the power supply can be stored under the clothes.

(Thermal imagers Quantum XDS) User interface

User interface

Actual information about the status of the thermal imaging device, depicted in the form of blue icons and numbers, is located on the data panel in the lower portion of the screen, and does not interfere with the image observed. When switching between various functions (digital zoom, colour inversion, brightness/contrast settings), the respective large sized icon appears in the right upper portion of the screen

(Thermal imagers Quantum XD&XQ) Controls


Main control functions (turning on and off the unit, sensor calibration, colour inversion/digital zoom) are carried out with the buttons on the upper panel. The size and location of the buttons are customised for comfortable use both with a gloved or bare hand. Brightness and contrast are set up with the controller wheel located next to the objective lens.
