Athermalization
Passive and active athermal designs using Invar, titanium, CFRP and compensating mechanical geometry.
Service Overview
Temperature is the silent killer of high-performance optics. AISYS engineers passive athermal designs that stay in focus across the full military temperature range (–40 to +71 °C) without moving parts — and active designs where the mission envelope demands them.
Material choice, spacer geometry and coupled optical/mechanical analysis are combined to deliver focus stability that is repeatable across production units.
What We Deliver
- Passive athermal design (material and geometry compensation)
- Active athermal designs with motorised focus compensation
- CTE-matched material selection (Invar, Ti, CFRP)
- Coupled optical + thermal FEA
- Focus-shift budgets across MIL temp range
- Bimetal and spring-loaded compensators

Frequently Asked
Do you achieve focus stability over –40 to +71 °C?
Yes — with a mix of Invar spacers, CFRP metering tubes and, where needed, motorised active compensation.
Can you retrofit an existing lens?
Often yes — by replacing spacer material and adding a compensator without changing the optical prescription.
