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.

High-durability and Hard-carbon AR Coatings

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 1024x768 XGA LWIR Cameras

The SupIR 2.6mm f/1.4 lens is designed for use with 1024x768 pixel array XGA format uncooled LWIR cameras with a 12 and 17 μm pixel pitch. It is also compatible with 160x120, 320x240, 384x288, and 640x480 format cameras with a 12, 17 μm pixel pitch.
