Faqs
Q1: What is an athermalized IR lens?
An athermalized IR lens is designed to maintain focus across varying temperatures without needing manual adjustment. It automatically compensates for thermal expansion and contraction, which can affect image clarity in infrared imaging applications.
Q2: How does an athermalized IR lens work?
It uses materials with differing thermal expansion rates or unique mechanical designs to counteract temperature-induced focal shifts. This allows it to remain in focus over a wide temperature range.
Q3: Why is temperature stability important in IR lenses?
IR lenses are often used in applications with significant temperature fluctuations. Temperature changes can cause expansion or contraction of lens materials, altering the focus. Athermalized lenses maintain clarity and focus automatically in these conditions.
