Zentron MEGA CQ25R: 640 25-mm system with LRF and four technical operating modes
The CQ25R is not a classic 50-mm long-range device, but a compact multifunction system with 640×512 VOx, 25 mm f/0.9, 17.5° × 14° field of view, integrated LRF, and M45×0.75 interface. Its strength is versatility – its risk of being a bad buy is exactly that versatility if you actually only need a simple handheld device.



Strength Wide 25-mm field of view, 640 sensor and LRF in a housing weighing only about 365 g.

Technical roles Designed by the manufacturer as monocular, clip-on, helmet, and scope modes.

Important fact fix In operation, the device runs on 1×18650; two 18650 batteries are supplied according to the manufacturer.

Limit 1,500 m detection is a thermal signature indication – not a reliable identification or usable distance.


The knowledge core: 25 mm means overview instead of maximum distance effect
The 25-mm f/0.9 optics deliver a significantly wider field of view of 17.5° × 14° than the 50-mm Q models. This helps with orientation, stalking, and observation in the near to mid-range. Those looking for maximum base magnification for wide field areas should compare a 50-mm device like Q50 or Q50R.
The 640×512 sensor with 12 µm and NETD ≤18 mK provides enough sensor reserve so that the wide image does not automatically mean "coarse overview." Still, the optics remain decisive: a 25-mm system shows more surroundings but less optical magnification than 50 mm.


Technical data with practical interpretation


Sensor
VOx uncooled
hlt, 640×512, 12 µm, 50 Hz – high detail reserve with smooth pans.


NETD
≤18 mK according to Zentron – reserve with low thermal contrast; weather and focus remain crucial.


Lens
25 mm f/0.9 – bright and clearly designed for overview.


Field of View
17.5° × 14° – roughly 30.8 × 24.6 m at 100 m.


Manufacturer Modes
Monocular 1.7×; Scope 1.4×; Helmet 1.1×; Clip-on 1×. Availability and permitted use may vary by region/firmware.


LRF
905 nm, Laser class 1, 5–1,200 m, ±1 m according to manufacturer.


Display
OLED 2560×2560 – high display resolution; does not replace sensor resolution.


Memory / Wireless
64 GB, Wi-Fi, Bluetooth, microphone, USB-C and ZEN LINK app.


Battery
1×18650 in device; up to 8 h according to manufacturer. Two 18650 batteries are listed as accessories.


Interface
M45×0.75; Quick-release Picatinny accessories are part of the system according to manufacturer.


Housing
Magnesium, IP67, 161.5 × 75.5 × 51 mm, approx. 365 g.





Buy if …
You want a wide field of view with a 640 sensor.
LRF and compact design are important together.
You actually want to use the different technical operating modes.
M45×0.75 and modular accessory connection fit your planned system.



Don’t buy if …
You’re only looking for a simple thermal handheld device.
50 mm base magnification for long-range observation is a priority.
You don’t want to check adapter and interface issues before purchase.
You automatically equate technical operating modes with legal permissibility.




MEGA CQ25R vs. Q50R vs. Q50
MEGA CQ25R: wide 25 mm field of view, multifunction concept, LRF and very low weight. Q50R: 50 mm and LRF for stronger distance character. Q50: 50 mm without integrated LRF, if rangefinding is not needed.
You can find more models in the ZENTRON manufacturer collection and in Thermal Imaging & Night Vision.


Practical tips for the multifunction concept

First define your role: Don’t buy the CQ25R just for “4-in-1.” What matters is which one or two roles you actually use regularly.
Check interfaces in advance: M45×0.75 refers to the device interface. Whether a specific adapter fits your existing optics or equipment must be confirmed separately.
Base image before digital zoom: The wide field of view is a core advantage. Constant high digital zoom takes away exactly this overview again.
Separate firmware and law: A technically available or later unlocked function is not automatically permitted in every region. Software version and current legal framework must be checked separately.



Scope of delivery and interfaces
The current Zentron page lists charger, eyecup, power supply, battery compartment, two 18650 batteries (70 mm), quick-release Picatinny mount, spare ring, Torx key, battery cover, cleaning cloth and USB-C cable. The exact scope of delivery of each batch remains decisive.
Manufacturer information, specific compatibility and applicable legal requirements apply for mounting/adapter configurations. Black Raptor does not treat a technical interface as a blanket usage approval.


FAQ
How many 18650 batteries does the CQ25R use simultaneously? The current Zentron specification lists 1×18650 as operating battery. Two 18650 batteries are included in accessories. How wide is the field of view? Zentron states 17.5° × 14°. This roughly corresponds to 30.8 × 24.6 m at 100 m and explains the overview-oriented character of the 25 mm optics. Does the CQ25R have a rangefinder? Yes. The integrated laser rangefinder is class 1 according to manufacturer, operates at 905 nm and measures from 5 to 1,200 m with ±1 m specified accuracy. What does 4-in-1 mean? Zentron describes technical modes for monocular, clip-on, helmet and scope use. Whether a specific use is technically compatible and legally permitted must be checked separately.
Is the CQ25R better than a 50 mm device? Not generally. The CQ25R offers more overview and modularity; a 50 mm device typically offers higher base magnification and is more focused on long-distance observation.
