Introduction to the SLIM Series
Thermal scopes have evolved from bulky, complex tools into compact, highly versatile devices—and the NOCPIX SLIM Series is proof of that transformation. Designed for professionals and avid hunters alike, the SLIM series delivers exceptional performance in a lightweight, rugged build that easily transitions between handheld use and rifle-mounted deployment.
Purpose-Built for Portability and Precision
The SLIM series is engineered for those who prioritize compact performance, combining a sleek magnesium alloy frame with advanced thermal detection capabilities. Whether stalking game through dense woods or surveying terrain at night, the SLIM keeps you agile and accurate.
Dual-Use: Handheld & Weapon-Mounted
A unique strength of the SLIM series is its dual functionality—as both a thermal monocular and a weapon scope. With Picatinny mount compatibility and throw-lever adjustments, switching from observation to engagement is seamless.
Key Features of the SLIM Series
Thermal Imaging Performance
Detector Quality and NETD
Both SLIM models feature 12μm pixel pitch detectors and a NETD of ≤18mK, ensuring fine thermal detail even in poor visibility—think foggy mornings, drizzling rain, or heavy brush concealment.
1024×768 AMOLED Display
The high-resolution 0.39″ AMOLED screen brings crisp visuals to life with excellent contrast, ensuring clear target identification under varying light conditions.
Optics and Viewing Comfort
Magnification Range and Digital Zoom
The digital zoom offers smooth transitions from 1x to 4x, allowing quick adaptation for scanning or close targeting. Paired with base magnifications tailored per model, this versatility ensures optimal field coverage.
Eye Relief and Exit Pupil
A generous 48mm eye relief and a 10mm exit pupil contribute to user comfort during extended observation or rapid reticle acquisition in dynamic scenarios.
Lightweight, Durable Build
Magnesium Alloy Body
Unlike many thermals, the SLIM uses a magnesium alloy housing, making it durable yet light, and ideal for long hunts or tactical deployment where weight savings matter.
Compact, Ergonomic Design
With dimensions of 216 × 76 × 46 mm and user-friendly button layouts, the SLIM series offers easy, intuitive operation even with gloves on.
Power Supply and Runtime
Replaceable 18650 Batteries
Each SLIM device runs on a replaceable 18650 lithium battery, with support for dual charging options via USB-C or magnetic cable—ensuring flexibility and ease of field use.
Multiple Charging Options
Recharge either with the included magnetic charging cable, a USB-C port, or via external battery packs—no need to remove the device from its mount.
Mounting and Setup
Picatinny Compatibility
Installation is simple with the included Picatinny dual-throw mount. Secure fitting and quick adjustments make mounting stable and repeatable.
Dual Throw Lever Adjustment
Fine-tune mount tension using the integrated tool, ensuring a snug fit every time without overtightening.
Zeroing Process and Precision Tuning
Freeze Zeroing Method
The SLIM employs a “freeze” zeroing method—take a shot, freeze the image, and adjust the reticle to match the point of impact. This method is efficient and intuitive, even for new users.
X/Y Reticle Adjustments
Adjustments are pixel-level precise, and the system calculates correction values based on distance and magnification, aiding in fine-tuned accuracy.
Recording, Photos & RAV Features
Recoil Activated Video (RAV)
Automatically captures 15 seconds before and 2 minutes 45 seconds after a shot. Perfect for reviewing hits, misses, and environmental context without manual activation.
Image & Video Capture, Memory Access
Store up to 32GB of video and photos, accessed via USB or Wi-Fi. Media is timestamped and neatly organized by date.
Connectivity and NOCPIX App Integration
Wi-Fi Control and App Pairing
Connect your mobile device to the scope via Wi-Fi, using the NOCPIX app to control functions, view footage in real time, and adjust settings remotely.

Menu System and Navigation
Quick Menu vs Main Menu
Adjust common settings quickly via the shortcut menu, or dive into advanced features using the main menu. The button layout ensures ease of navigation even under pressure.
Parameter Adjustments Made Easy
From contrast and brightness to reticle zero profiles and standby timers, nearly every function is a few clicks away.
Reticle and Color Customization
Reticle Types and Colors
Choose from 7 reticle types and 8 color schemes like Black Red, White Green, Crimson, and more for personalized targeting comfort.
Color Palettes and Ultra-Clear Mode
Toggle between White Hot, Black Hot, Red Hot, and multiple pseudo-colors. Enable Ultra-Clear Mode in low-contrast settings to enhance image clarity.
Advanced Functions and Settings
Pixel Defect Correction: Clean up screen imperfections with pinpoint accuracy.
Motion Sensor: Automatically triggers standby based on tilt angles.
Image Hue: Switch between warm and cool modes for eye comfort.
