Pulsar HD50S Quantum Thermal Imaging Scope Monocular 384x288 50Hz (PL77321)



The Quantum S 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.      

Operating modes

The Quantum S 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).    

Quick start-up time 

The Quantum imaging scopes feature short start-up time (5 - 7 seconds) from the push of a button to full operational status. This is one of the best results in its class.    

High refresh rate

The 30 Hz refresh rate provides a smooth and consistent image of moving objects. 

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) 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.
