Tamron is a world-leading supplier of industrial and OEM lens assemblies used in virtually every industry around the world. Recently Tamron introduced a family of zoom lenses for LWIR thermal cameras delivering unrivaled value and performance. Sierra-Olympic Technologies has been a keystone customer and partner for Tamron since this introduction of very high performance LWIR zoom lens assemblies for OEM and security/surveillance applications.


Sierra-Olympic Technologies has delivered thousands of infrared zoom lenses since its foundation in 1995.  Addressing all infrared wavelengths in SWIR, MWIR, and LWIR, Sierra-Olympic had developed comprehensive expertise and tools for the evaluation and integration of thermal imaging zoom lenses across almost all large vendors.  Based on this experience, Sierra-Olympic can assure that the Tamron zoom lenses deliver the highest performance in repeatability, athermalization, parfocality, MTF when measured against other thermal zoom lenses. Sierra-Olympic is a stocking distributor making every effort to maintain inventory for fast delivery.  Since we are a keystone customer, we have deep technical experience with the lens having integrated and shipped hundreds of units to customers around the world.
