Jerry-YM 2.0 / RIX ST6 Defender Thermal Lens Protector

The Cold Harbour Jerry-YM 2.0 Defender Thermal Lens Protector provides rugged protection and impact resistance to the Jerry-YM 2.0 family of devices including the RIX STRIDE ST6. Using the same proven, multi-hit rated, temperature-stable proprietary TPU material as our COTI Defender, the Jerry-YM 2.0 Defender can be reliably used in any force-on-force scenario with no damage to the host device.

Key Features:

• Precision slip-fit over the objective lens for fast install and has a small lip to securely lock into the objective lens
• Cat-Tail Throw Lever built into the protector for fast focusing
• Allows use of the factory rubber cover for added protection during storage

Recognizing that each user's requirements are unique, three different protection levels are available that include the following components:

Optical-grade, transmission-optimized Germanium sacrificial lens optimized for 8-14µm wavelength, is tested to absorb up to a 0.2g BB at 350fps and UTM and Simunitions at point blank range with no penetration. Not multi-impact-rated.
Multi-Impact Rated custom-manufactured Titanium Honeycomb

Level 1 - Germanium sacrificial lens only. This option provides impact protection with the highest levels of performance with no perceived signal degradation. Ideal for users who want maximum performance and thermal signal while still protecting the host lens. Not ideal for situations where multi-hit capabilities are required.

Level 2 - Titanium honeycomb only. A custom-fabricated titanium honeycomb offers multi-hit resistance and has been tested for 400fps with 0.2g BBs at point blank range. Depending on frangibility of ammo relative to the ruggedness of the titanium, spalling of projectiles is possible. There is approximately ~5-10% reduction in thermal signal. Due to reduced thermal signal, there is a benefit of reduced thermal noise.

Level 3 - Germanium lens + titanium honeycomb. The ultimate in protection. Both materials are used in tandem for maximum protection and safeguards against spalling. While this combination is multi-impact rated, due to the fragile nature of germanium and spalling, durability of the germanium is not guaranteed.
