Lenses for Mid-Wave Infrared (MWIR) Cameras for 3–5 µm

MWIR Continuous Zoom Lens

Shape Optics provides MWIR continuous zoom lenses for thermal imaging systems operating in the 3–5 µm wavelength range. Designed for integration with compatible cooled infrared detectors, these lenses provide adjustable focal lengths for wide-area observation and long-range imaging.

Available configurations support motorized zoom and focus control, allowing integration into thermal imaging cameras, surveillance platforms, and other infrared systems requiring variable fields of view.

MWIR Continuous Zoom Lens Overview

Seamless Zoom Capability

Continuously adjust the field of view without fixed magnification steps, allowing precise framing and target tracking at any distance.

Accurate Target Tracking

Maintains image clarity and focus during zoom operations, supporting effective target acquisition, recognition, and tracking.

Superior Image Quality

Optimized for MWIR imaging with advanced infrared materials and coatings, ensuring high resolution, contrast, and thermal sensitivity throughout the zoom range.

Motorized Operation

Available with integrated motorized zoom and focus mechanisms for remote control and automated system integration.

How Does Continuous Zoom Work?

A continuous zoom system adjusts the effective focal length smoothly across its designed zoom range without switching between fixed focal-length positions. This allows operators to change the field of view while observing a scene.

Shorter focal lengths provide a wider field of view for area observation, while longer focal lengths provide narrower views for examining distant objects. Motorized zoom and focus mechanisms can support remote operation and integration with camera control systems.

Key Considerations for Lens Selection

Selecting a suitable MWIR continuous zoom lens depends on detector compatibility, optical performance, and operating conditions.

Parameter Selection Considerations
Focal Length & Zoom Range Determine the required field of view, magnification, and observation distance.
Detector Compatibility Match detector resolution, pixel pitch, and image format.
F-number (F/#) Evaluate aperture requirements and compatibility with the cooled detector system.
Optical Performance Consider MTF, distortion, transmission, and image quality throughout the zoom range.
Motorized Control Review zoom and focus mechanisms, control interfaces, and system integration.
Environmental Conditions Consider operating temperature, vibration, and mechanical constraints.
