LWIR Thermal Imaging Lens Assemblies
Thermal Imaging Lens Assemblies for Variety of Detectors and Focal Lengths
Available with AR, DLC or Filter Coatings
Custom Design of Optics and Mechanics Available
Overview
LightPath offers both custom and standard lens assemblies for Thermal Imaging in MWIR (3-5um) and LWIR (8-12um) applications. Our Thermal Imaging Lens Assemblies (TILA) utilize a variety of materials, including our proprietary BD6 Chalcogenide Glass. Leveraging our internal glass manufacturing, broad fabrication technologies and our optical system design team we are vertically integrated to be responsive to your product development needs. Additionally, both standard and custom assemblies can be offered with 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 assembly to your specific requirements, but our team can also develop customized optical coatings to include spectral filtering that reduce background noise, withstand specific environments or chemicals, and can handle high angles of incidence. For further details, contact us today.
Advantages
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
