Pulsar presents a new HD digital night vision
, and introduces
state of the art 40 mk sensor technology
in the manufacturer’s top of the line Thermal
Imaging products. The updated products showcased at the 2020 SHOT Show
include the Helion 2 Thermal imaging monocular, the Trail 2 LRF –
Thermal imaging riflescope with built in laser rangefinder, and the
Thermion XQ line of Thermal imaging riflescopes.
To most of us, that a 40 mK NETD, 17µm
uncooled Amorphous Silicon microbolometer sensor is being integrated
into a thermal imaging optics makes little impact; it’s just a technical
jargon that is not easily comprehensible to the layman. But
it actually does make a lot of impact on the
performance of a thermal imaging device, almost to the point of being
The NETD (noise equivalent temperature difference)
describes the ability of a thermal imaging device to distinguish between
little differences in IR radiation of the observed object in the image.
It is measured in milli-Kelvins (mK). Typical
values for mainstream thermal imaging devices built for hunting, sports
and leisure are in the region of 70-50 mK, with the lower number the
Sensors with better NETD value will allow
PULSAR units t
o perform more efficiently in conditions when
temperature differences are very low and it’s hard for thermal imaging
units to produce detailed contrasted image.
All Pulsar 2020 year models onwards based on
17 µm pixel pitch FPA (Focal Planar Arrays) will feature 40 mK sensors,
thanks to an exclusive contract that Pulsar has signed at the end of
2019 with its sensor supplier for buying only select sensors with 40 mK
Digex N450/N455 is a new digital night vision riflescope
from Pulsar that follows the
set, engineering the optronic device to be
contained in a metal housing designed to appear as a traditional daytime
riflescope featuring a standard 30 mm mounting surface tube.
Both the Pulsar Digex N450 and N455
share the same features: a new CMOS HD (1280x720) night vision sensor
with high sensitivity (specs are very similar to the Digisight Ultra
family of digital riflescopes), a crisp 1024x768 AMOLED microdisplay,
Built-in video recorder with integrated 16 Gb memory, combined B-pack
battery system that is the same used in Thermion riflescopes.
The difference between the Digex
N450 and N455 is the wavelength of the detachable high power IR
illuminator: 850 nm or 940 nm respectively. The 850 nm IR features
long-range action, the 940 nm IR operates in the invisible range, for a
performance that reaches 550 m in range.
