IRG206 Double-sided AR & AR+HD Coating

IRG206 (As₄₀Se₆₀) chalcogenide glass window is a core optical component for 8-12μm long-wave infrared thermal imaging. We provide two professional coating versions for different application scenarios: Double-sided Pure AR Coating and AR+HD Composite Coating

Description

Coating Option 1: Double-sided Pure AR Coating

Substrate Material: IRG206 Chalcogenide Glass (As₄₀Se₆₀)
Coating: Double-sided LWIR anti-reflection coating, without HD hard protective layer
Wavelength: 8-12 μm (LWIR thermal imaging band)
Typical Transmission: 8% ~ 98.5% @8-12 μm, average ≥97%
Feature: Ultra-high transmission, flat spectral response, maximum infrared light transmittance, excellent optical consistency.
Application: Indoor thermal cameras, fixed monitoring equipment, indoor precision thermal imaging devices (stable environment, no severe friction and corrosion)

Coating Option 2: AR+HD Composite Coating

Substrate Material: IRG206 Chalcogenide Glass (As₄₀Se₆₀)
Coating: AR+HDcomposite coating
Wavelength: 8-12 μm (LWIR thermal imaging band)
Typical Transmission: Average Tave=94.72% @8-12 μm
Feature: Super scratch resistance, friction resistance, moisture resistance and salt spray resistance.
Application: Automotive night vision, outdoor thermal monitoring, industrial thermal imaging, vehicle-mounted and airborne harsh environment equipment.
