Custom Made Optics For Oem Edmund Optics Athermalization is a type of ruggedization that mitigates the harmful effects of thermal expansion and defocus in optical and imaging systems. While active athermalization makes use of less exotic optical materials and is more robust for use in application environments with larger operating temperature ranges, this type of athermalization can be bulkier and more costly to implement.
Athermal Edmund Optics Athermalization is a ruggedization for applications in extreme or changing temperatures. join us for a 30 minute webinar presented by edmund optics' experts nick sischka and boris lange to learn about how athermalization protects imaging lenses from extreme temperature environments. Athermalization ruggedization is done to maintain imaging performance throughout significant temperature swings, which is ideal for applications like aerospace systems. passively athermalized lenses achieve this through creative groupings and spacings of lens elements or by using exotic glass types. Athermalization ruggedization is done to maintain imaging performance throughout significant temperature swings, which is ideal for applications like aerospace systems. passively athermalized. These imaging lenses, available exclusively from edmund optics, are the latest addition to a growing number of products that have ruggedized designs for more demanding applications within harsh environments.
