Leveraging our Infrared Optics manufacturing technologies, as well as our Optical System Design and vertical integration capabilities, LightPath offers both custom and standard lens assemblies for Thermal Imaging in MWIR (3-5um) and LWIR (8-12um).
Our Thermal Imaging Lens Assemblies (TILA) utilize a variety of materials, including primarily our proprietary BD6 Chalcogenide Glass. Additionally, both standard and custom assemblies can be offered with standard AR, High Durability AR (HDAR), Diamond Like Carbon (DLC) and spectral filter coatings, all developed and produced in-house.
Not only can LightPath customize the design of the assembly or design a new assembly to the customer’s specific requirements, but our team can also develop and customize the optical coatings to include spectral filter coating on the lens to reduce background noise, durable DLC to withstand specific environments and chemicals, and high angle of indigence coating, just to name a few.
For further details, see below our standard lens assemblies, TILA Tutorial or contact us for a custom design for your needs.
Performance Advantages
- Optical designs utilize high performance aspheric surfaces with diffractive dispersion correction
- BD6™ chalcogenide material enables optical athermalization and high transmission; passive athermalization for -40C to +80C
Precision Glass Molding Expertise
- Precision molded lenses using high-quality chalcogenide glass
- Precision Glass Molded (PGM) technology is ideal for scaling to high volume while maintaining tight tolerances
Manufacturing Capabilities
- Cost-effective, global manufacturing capabilities with world-class engineering expertise
- High-efficiency AR coatings for full LWIR band (8-14 um), with optional DLC added protection
