Pulsar Quantum HD50S Hand Held Thermal Optic



Having used the HD50 extensively in the field it has become a favorite with our team due to its class leading light weight and long battery life.

The image processing is focused on contrast and does a really good job of detection. Heat sources show brighter than comparative units.

Quite a challenge for thermal devices is maintaining a  usable picture on the horizon (lots of  sky at a temperature of -something Deg and ground at + something Deg) the pulsar hd50 is a top performer in this area.

Under adverse conditions, not much temperature difference in a scene, the pulsar maintains an image with plenty of detail, while other thermal products are experiencing grey out effects and massively reduced situation awareness.

What lens to choose?

The Hd38 and Hd50 are neck and neck on Detection (we use them side by side in the field). The Hd38 wins on a wider field of view and is slightly less focus fussy. You may choose this over the HD 50 if you like to spot on the move a lot.

The hd 50 has a slight advantage when it comes to identification.

Range wise both units can detect a fox size target out to 600mtrs plus depending on the conditions.

As with all thermal optics there is a huge difference between a static and a moving target. To have any hope of identification at 600mtrs (and a lot closer sometimes) both units would need the target to be moving.

Plus Points:-  light weight , battery life, contrast.


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).

image 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).

image 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.

image 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.

image 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.
