Guide TA435 Thermal Imaging Front Attachment

The Guide TA435 is a versatile thermal imaging attachment that transforms your daytime riflescope into a thermal optic in seconds—without requiring re-zeroing. Lightweight at under 400 g and built with IP67-rated durability, it’s designed for quick deployment and reliable performance even in harsh environmental conditions—from foggy forests to sweeping plains.

Powered by a sensitive 400 × 300 VOx sensor (17 µm pixel pitch) and a fast 35 mm f/1.2 lens, the TA435 delivers clear thermal imagery with an angular field of view of approximately 10.7°, or roughly 10 m × 8 m at 100 m. A full-color 0.39″ OLED display with 1024×768 resolution renders rich visuals, while a 2×–4× digital zoom enables detailed observation when closed-focused viewing is needed.

About the Guide TA Series

The TA Series offers dual functionality in a compact device—use as a standalone thermal monocular or simply clip it onto a daylight optic using standardized adapter rings (40–70 mm), with no need to re-zero your scope. Proprietary stray-light control design ensures optical accuracy, while fast toggle between scene modes such as Forest, Snow, Desert, and City helps maximize clarity across environments. Rugged, reliable, and easy to mount—it’s the ideal clip-on companion for on-the-go thermal imaging.
