SWIR Zoom Optical System

SWIR Zoom Optical System

The SWIR continuous‑zoom lens system delivers long‑range surveillance and precision sensing for the 0.9–1.7 μm spectrum. Featuring high zoom ratio and large‑aperture design, it cuts through haze, smoke and dust for sharp long‑distance imaging, ideal for InGaAs camera integration.
Key Features
1.200–1200mm Continuous Zoom: Ultra‑long focal length for long‑distance target identification
2.Strong Haze Penetration: Clear imaging through fog, smog and marine humidity
3.Precision Motor Control: Fast, smooth zoom/focus with sub‑millimeter accuracy
4.High‑Transmission Coatings: Maximize light input and reduce ghosting & flare
5.Rugged Mount: Vibration‑resistant bracket for vehicle‑mounted applications

Description

The SWIR continuous‑zoom optical system delivers top‑tier long‑range infrared imaging. Unlike thermal cameras, it captures reflected light for higher resolution, seeing through glass, haze and airborne pollutants.
Built with a modular, rugged housing, it safeguards precision internal lens components. Its motorized belt‑drive design ensures high reliability and easy integration with PTZ platforms. Featuring low‑dispersion glass and precise mechanical alignment, it maintains stable optical center across the full zoom range, perfect for defense, coastal security and scientific observation.

Application Scenarios

 

  • Semiconductor Inspection: Non-destructive imaging through silicon wafers for crack detection and alignment.
  • Material Sorting: Identifying plastics, textiles, and minerals by their unique spectral signatures in the SWIR band.
  • Defense & Security: Long-range surveillance through fog, smog, and dust; laser spot tracking (1064nm/1550nm).
  • Agriculture: Monitoring crop hydration levels and fruit bruising detection through skin layers.
  • Scientific Research: Astronomical observation and biomedical fluorescence imaging.

 

Key Functions & Advantages

 

  • Manual Precision: Tactile manual focus and iris rings with industrial-grade locking screws to prevent shifting under vibration.
  • High Contrast Imaging: Specialized internal baffles and coatings significantly reduce stray light and ghosting.
  • Superior SWIR Transmission: Specifically designed glass elements (not standard optical glass) provide higher throughput for short-wave infrared photons.
  • Modular Flexibility: Available in multiple focal lengths to suit various Fields of View (FOV) requirements, from wide-angle surveillance to narrow-field inspection.
  • Easy Integration: Lightweight and compact form factor allows for integration into hand-held devices or cramped industrial enclosures.
