Ultra-Thin Flexible Heater for Optical Sensors | Camera & LiDAR Heating

Lens fogging is caused by condensation from temperature differentials. We recommend attaching ClearView PI Flexible Heaters directly around the lens barrel or at optical window edges.

Based on 821+ client projects, maintain lens temperature 10°C–15°C above ambient for automotive cameras. Our 0.22mm ultra-thin profile avoids optical interference.

Installation: Use 3M high-temperature adhesive on the lens mount or filter edge.

1. Bubble-free bonding: Air bubbles cause localized overheating and optical path distortion — full contact is mandatory.
2. diameter/inner diameter (e.g., OD 24mm / ID 16mm) to ensure that the heating zone remains outside the effective aperture.

1. Increase power density: Raise wattage within safe limits (max 1.5 W/cm²).
2. Reduce heat loss: Add insulation or use a higher-conductivity aluminum mount.
3. Voltage adjustment: Power scales with V² — a 20% voltage increase yields ~44% more power (P ∝ V²).

Core Rule — Never Run Unloaded: High-power heaters (resistance <10Ω or high power density) must never be energized without a heat sink.

Ensure tight contact with a heat-dissipating body (e.g., aluminum mount). For extreme power levels, replace adhesive with mechanical clamping to prevent carbonization at elevated temperatures.

Anti-vibration: Use a “sandwich mounting” technique — clamp the heater between two metal plates (ideal for 5G base stations or EV applications).

Screw Mounting:

• Never self-drill holes — even for 800mm+ units. All holes must be pre-engineered to route around internal heating traces.

Always install insulating washers to prevent screw edges from cutting through the polyimide (PI) layer, which would cause a short circuit.

⚠ Never Self-Drill : Always request pre-designed mounting holes from ClearView engineering before production.

Environmental Limits: Standard adhesive and wiring will embrittle and fail at -270°C.

Space/Vacuum Grade: ClearView PI material has aerospace-grade properties. Suggest using mechanical clamping instead of adhesive in vacuum environments.

Flexible Heater (bonded to IC underside or clamped between heat sink): Best for space-constrained, precision localized heating.

PTC Fan Heater: Better suited when you need to warm an entire enclosure space.

Installation Note: When sandwiching between IC and heat sink, always use thermal interface compound to minimize thermal resistance.

Definition: This value represents the equilibrium temperature measured when the heater is suspended freely in still air at room temperature.

Practical Note: Actual operating temperatures are significantly affected by ambient airflow, substrate material (aluminum vs. glass), and ambient temperature. This figure is for reference / model selection only. Physical sample testing is strongly recommended.

★ Advisory : Always conduct real-world sample testing. Listed values are model-selection guides only.
