Long Range Large Size MWIR Thermal Imaging Zoom Lenses

Introduction:

For long range thermal imaging, MWIR Thermal Imaging Camera Lenses have been a favored option over LWIR Thermal Lenses. This is because MWIR thermal imaging lenses, coupled with high-sensitivity cooled detectors deliver better thermal contrast, being competent at rejecting thermal noise, and clutter and discriminating similar heat when the thermal radiation is weakened due to long traveling distances. This characteristic of MWIR thermal imaging lenses allows the recognition and identification of targets in distant areas.

Hangzhou Shalom EO presents its latest success in mid-wave infrared (MWIR) thermal imaging technology: the 75mm-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lenses, Code 313-010. This long range MWIR thermal imaging lens features a long detection distance of over 35km and extensive focal lengths ranging from 75mm-1100mm, large size, and aperture (f4.0). Shalom EO’s 75mm-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lenses are designed to meet the demands of advanced thermal imaging applications, where remote surveillance coverage and high image clarity are paramount.

1. Extensive Focal Length Range and Long Detection Range

With a focal length ranging from 75mm to 1100mm, these MWIR lenses are capable of providing detailed thermal images at considerable distances. Users can zoom at will within the focal length boundaries and switch unrestricted between close-up observations at long focal lengths and panoramic sight at short focal lengths.

Provided the longest focal length exceeding 1000mm, Shalom EO’s 313-010 module is optimized for long range thermal imaging, and a detection distance of >35km can be achieved. The long detection range of over 35km ensures accurate thermal imaging even in remote or hard-to-reach locations, making the lenses ideal for border monitoring, long-range observation, and other applications where maintaining image quality over distance is crucial. Users are allowed to recognize vehicles, personnel, drones, and objects at extreme distances, elevating the awareness of threats at initial stages.

2. Large Size and Aperture f/4.0 for Expanded Infrared Radiation Capture

Compared with Shalom EO’s previously released code 313-004 Ultra-Lightweight 90-1100mm f/5.5 Continuous Zoom MWIR Thermal Imaging Camera Lens Modules, the 313-010 75-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lens Module boasts a larger f-number of f4.0. Having a larger f-number allows for a significant increase in infrared radiation input. (You can click here to learn more about What is f-number).

The large aperture leads to higher image clarity and greater sensitivities in thermal detection. The ability to capture more infrared energy enhances the performance in both high-contrast environments and low-light conditions, making them suitable for a range of scenarios, from security surveillance to industrial monitoring.

3. Continuous Zoom Mechanism

The built-in motorized continuous zoom mechanism allows users to smoothly transition between different focal lengths without losing image integrity. This functionality provides flexibility in various operational contexts, enabling users to adjust the field of view as required for both wide-area surveillance and detailed focus on specific targets. The seamless motorized zoom control ensures that critical details are preserved throughout the observation process.

4. Reliable Optical Performance and Durability

The optical lens components composing the lens module are fabricated using high-grade optical materials, and the lens components are produced with high precision standards to obtain unmatched optical performance. AR coatings are utilized to increase optical transmission and DLC coating is deposited at the optical front of the lens for protection.

The MWIR thermal imaging camera lenses, utilizing constructions based on knowledge-informed design and incorporating mechanical and optical elements manufactured using top-class materials are devised to stand the rigors of exposure to various environments and to multiple weather conditions.

5. Applications:

This 75mm-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lens module is well-suited for use in defense, industrial inspection, and environmental monitoring.

6. Comparison with the 313-004 90-1100mm f/5.5 Continuous Zoom MWIR Thermal Imaging Camera Lens Modules

Compared with Shalom EO’s 313-004 Ultra-Lightweight 90-1100mm f/5.5 Continuous Zoom MWIR Thermal Imaging Camera Lens Module, the 313-010, 75-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lens Module boasts a greater f-number, hence a larger amount of MWIR radiation is permitted to enter, resulting in more image details and enhancement of overall image brightness.

In addition, the focal length range of the 75-1100mm/f4.0 MWIR continuous zoom thermal Imaging Camera lenses is also wider, with access to shorter focal lengths down to 75mm, users are able to bring extended views and scopes into focus.

However, the 313-010 75-1100mm/f4.0 MWIR Zoom Thermal Imaging Camera Lens Module is heavier than the 313-004 Ultra-Lightweight 90-1100mm f/5.5 Continuous Zoom MWIR Thermal Imaging Camera Lenses, which only weigh 4.2kg. The weight of this large size f4.0 module is about 8.0kg. Nevertheless, Shalom EO’s 313-010 long range MWIR thermal imaging camera lenses are still much lighter than many of the counterpart lenses from other suppliers.
