Name: ZnSeレンズ
Rating: 4.5 (100 reviews)

主な特徴

Dual-band compatibility

Transmittance range covers 0.5-22 μm, perfectly compatible with mid-wave infrared (MWIR) and long-wave infrared (LWIR), with optimal performance at 10.6 μm.
Preferred for high-power lasers

Extremely low absorption coefficient (< 0.0005 cm⁻¹ @ 10.6 μm), strong thermal shock resistance, making it an ideal material for handling high-power CO₂ lasers.
Visible light-assisted alignment

Has a certain transmittance in the visible light band (pale yellow or orange), making system optical path alignment much easier than with silicon lenses (completely opaque).
Material Characteristics

Relatively soft: Mohs hardness is only 2.5~3, easily scratched during processing, unsuitable for harsh environments; Good chemical stability: Non-hygroscopic, chemically stable. Good chemical stability: Non-hygroscopic, chemically stable.

仕様 ZnSeレンズ

レーザーフォーカスレンズ

ECOPTIKは米国から輸入したCVD材料を使用しており、不純物による吸収がなく、散乱損失が非常に低いため、高出力CO2レーザーシステムの光学デバイス製造に最適な材料となっています。さらに、全透過帯域だけでなく、様々な光学系でも広く使用されている材料です。

適切なレーザー波長 λ=10.6um、通常の焦点距離:F38.1mm、F50.8mm、F63.5mmなど。

ECOPTIK はカスタマイズされた生産を提供します。

代表的な応用分野

High-power CO₂ laser processing

Used as focusing lenses and protective windows in laser cutting, welding, and marking machines, capable of withstanding laser power from hundreds to thousands of watts.
Infrared thermal imaging and FLIR systems

Used in the manufacture of thermal imager lenses to capture the long-wave infrared radiation of objects, widely applied in security, temperature measurement, military night vision, and other fields.
Spectroscopy and medicine

As a key component of Fourier transform infrared spectrometers (FTIR); also used for beam calibration in medical lasers and biomedicine.
