Features
High Performance Long Wave Focal Plane
Using advanced technologies, top-quality materials and unique coating techniques, together with innovative engineering and opto-mechanical designs, we have earned a reputation for excellent performance, durability and quality.
Hard-carbon AR Coating
Our highly abrasion-resistant, anti-reflective advanced optical coatings include several types of Hard Carbon coatings which provide maximum durability, energy transmission & minimal reflection. Our innovative coating technologies include:
- Physical Vapor Deposition (PVD) – Thermal heating and electron gun
- Ion Assisted Deposition (IAD) – Ion gun
- Plasma Enhanced Chemical Vapor Deposition (PECVD) for DLC coatings
Passive Athermalized Lens Assembly
Our IR imaging lens assemblies incorporate passive athermalization of the lenses and opto-mechanical system to maintain the highest imaging performance over the full operating temperature range. We use advanced materials that enable unique athermalization properties and optomechanical designs that effectively compensate for optical variations over a wide temperature range.
Designed for 640x480 Format LWIR Cameras
The SupIR 33.5mm f/1.3 lens is designed for use with 640x480 pixel array uncooled LWIR cameras with a 12 μm pixel pitch. It provides a 13.1° horizontal field of view.
