UV, IR, and SWIR Lenses for Specialized Applications

Infrared and ultraviolet lenses can be costly, and locating one that fits particular requirements can be challenging.

Most of the numerous UV, IR, and SWIR lenses Resolve Optics has created over the years are intended for specific uses. The lenses in this section are some examples of the variety of lenses Resolve Optics has produced.

The 231-000 lens utilizes the same optics as the 228-000 lens and targets research facilities. It features a simple mount with iris control, allowing customers to adapt and mount the lens according to their requirements.

The 231-000 63 mm UV lens was specifically crafted for research and development. Equipped with a basic mount offering iris control but not focusing, the lens can be customized and mounted according to user specifications. Additionally, Resolve Optics offers focus adapters upon request.

228-000 60 mm f/3.5 UV Forensic Lens

Engineered exclusively for forensic Reflective Ultraviolet Imaging System (RUVIS) applications, this is a comprehensive, high-efficiency UV forensic lens.

Leveraging a novel telescopic focusing mount, the lens achieves an extended magnification range, offering substantial movement within an exceptionally compact form. It is perhaps the first lens capable of imaging objects from infinity down to 1:1.25 magnification without needing add-on adapters.

Small lens and compact design complement the portable RUVIS system concept.

A larger field of view is crucial to accommodate fingerprint applications, ranging from 8.3º at 1:1.25 magnification to 16.6º at long object distances. This aspect is fundamental to realizing many of the technical improvements outlined here.

Enhanced lighting efficiency is achieved due to the 228-000 lens, with its expanded field of view, positioning both UV lights and UV imager closer to the object than longer focal length lenses, providing an identical view.

As light level varies proportionally to the square of the object distance, the increase in lighting efficiency is approximately determined by the ratio of focal lengths. For instance, substituting an 80 mm lens with the new 60 mm lens results in an augmented lighting efficiency of (80/60)² = ×1.78, corresponding to 78% more light on the scene.

By employing meticulous design and selecting appropriate glass types, coupled with advanced AR coatings, Resolve Optics Model 349 Series SWIR lenses achieve unparalleled resolution and color correction. This guarantees optimal image quality from the camera or sensor.

The 349-000 Lens is purposefully designed for the SWIR waveband, ranging from 0.9 to 1.7 μm. Unlike many off-the-shelf lenses targeting the SWIR market, primarily designed for the visible spectrum and only feature AR coatings for the SWIR bandwidth, the 349-000 Lens is tailored specifically for the SWIR range.

Consequently, there is a notable decrease in resolution and inadequate color correction. Resolve Optics Ltd has meticulously chosen the glass types incorporated in the design of SWIR lenses to ensure that lens performance within the 0.9 to 1.7 μm range no longer limits the ability to deliver the highest-quality image to the camera.

Resolve Optics provides NB lenses tailored to precise specifications in line with the tradition of crafting custom lenses.

The 16 mm SWIR lens from the 363 series was created specifically for the SWIR wavelength. The design uses carefully chosen glass kinds and AR coatings to guarantee optimal image quality and maximum transmission in the SWIR band.

Many off-the-shelf lenses targeting the SWIR market are primarily designed for the visible spectrum but are equipped with AR coatings for the SWIR bandwidth. This often leads to a notable decrease in resolution and inadequate color correction.

Resolve Optics Ltd has meticulously chosen the glass types utilized in the design of their SWIR lenses to ensure that lens performance within the 0.9 to 1.6 μm range no longer restricts the ability to provide the best possible image to the camera.
