Opto Engineering MWIR Infrared Lens

Medium-Wave Infrared Lenses

Opto_IR_MWIR_pic

Medium-Wave Infrared Lenses, MWIR series is a range of medium-wave infrared lenses specifically designed to operate in the 3-5 μm wavelength region with InSb Focal Plane Arrays (FPA). These lenses can be equipped with a standard Bayonet mount or an optional custom mount interface.

In the design of the lenses, great importance was attached to a good image quality and a large aperture (small F/#).These lenses, mounted on a MWIR camera, are the perfect choice for a variety of applications, including imaging through fog, high-speed thermal imaging, thermography, R&D (MWIR range), non-destructive testing

Tech Info

COATING
Opto Engineering MWIR and LWIR thermal lenses are HCAR coated These thermal lenses are specifically designed to meet the needs of those applications with optical elements exposed to harsh environments, such as military vehicles and outdoor thermal cameras. This coating offers highly protective properties coupled with good anti-reflective performance, protecting the outer optical surfaces from high velocity airborne particles, seawater, engine fuel and oils, high humidity, improper handling, etc.. It offers great resistance to abrasion, salts, acids, alkalis, and oil.

INTERFACE
All Opto Engineering IR lenses can be equipped with any custom mount interface. Each infrared camera comes with a different detector format and a different mount interface. This is why Opto Engineering has decided to provide any custom mount interface with any infrared lens at no additional cost so that these lenses can be integrated with any camera mount.

FOCUSING
Manual focusing mechanism, large field of view and low distortion.

HIGH RESOLUTION
Opto Engineering infrared lenses are designed for high resolution detectors up to 15 ?m pixel pitch and 21 mm diameter. Common infrared lenses are designed and optimized for Focal plane arrays (FPAs) with 30 ?m pixel pitch. However, as a trend, pixels are constantly decreasing their size: Opto Engineering IR lenses are compatible with the newest high resolution FPAs.

SPECIFIC QUALITY TESTING SYSTEM
Since no standardized and/or appropriate quality measurement system is available, Opto Engineering designed and developed a specific optical test bench for Infrared (IR) optics. The system design is based on Opto Engineering proprietary design optical benches used in the visible range. Opto Engineering developed reliable test procedures for checking IR optics quality and resolution (MTF: Modulation Transfer Function): each lens is checked by an experienced operator.

ATHERMALIZATION
Opto Engineering R&D team has proven expertise in designing challenging and demanding custom projects that successfully integrate optics and their mechanical housing. Upon request, Our engineering team can develop both active and passive athermalized systems, either optically or mechanically compensated, that work in environments characterised by significant temperature changes.
