Guide Orion C Series – Revolutionary thermal imaging attachments with ApexVision™
Guide Orion C Series – Thermal Imaging Attachment
The Orion C series was developed for hunters who want to eliminate every unnecessary gram – without sacrificing image quality or reliability. Consistently reduced to the essentials: maximum handling on the riflescope, lightning-fast readiness for use, and a crystal-clear thermal image. No unnecessary media functions, no distractions. Just the animal. Just the shot.
The heart of both models is the ApexVision infrared system The latest generation – featuring the Hyper-Light 2.0 AI image algorithm for a smooth, stable thermal image with fine details, even at greater distances. It also boasts a 3-second cold start, simplified button operation that's intuitive even with gloves, and recoil resistance up to 6.000 J. No frills – just everything that matters.
Extremely lightweight & compact
Total weight 285 g. Minimal shift in the center of gravity at the glass – you can hardly tell that the device is mounted.
Very good handling
Slim design, short overall length. The setup remains balanced and easy to handle – even during long periods of sitting.
Excellent thermal imaging
ApexVision with NETD 15 mK and AI algorithm Hyper-Light 2.0 for high-contrast, smooth images.
3 second start time
Instantly ready for a direct hit or unexpected encounter. No long wait for operating temperature.
Easiest operation
Reduced key layout, intuitive even with gloves. No nested menus, no unnecessary frills.
Robust & weatherproof

O435CS or O635CS – which is a better fit?
The difference lies in the sensor. Guide Orion O435CS It uses a 400×300 pixel detector and a narrower field of view – ideal for use in dense tree cover and under heavy vegetation. The lower power consumption of the smaller sensor gives it approximately one more hour of running time per battery (8 h vs. 7 h). That O635CS offers the significantly larger field of view of a 640×512 detector with 12,5°×9,4° – ideal for open areas and fast WildBoth models weigh the same and share the same robustness. The choice depends on the terrain.
Note: Both models are identical in construction and differ only in sensor resolution, field of view and display.
Adapter rings for different lens diameters are available as an option.
