700 nm – 14 µm
Infrared Precision Optical Components
High-performance IR optics engineered for thermal imaging, spectroscopy, sensing, and defence applications from 700 nm to 14 µm.
Infrared Optics Expertise
iC Optronics supplies a comprehensive range of precision infrared optical components, carefully sourced from leading manufacturers to meet the exacting requirements of thermal imaging systems, FTIR spectrometers, gas sensing instruments, defence electro-optics, and industrial process monitoring.
Our IR optics portfolio spans the near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) spectral regions. Substrate options include germanium, zinc selenide, zinc sulphide, silicon, calcium fluoride, barium fluoride, and chalcogenide glass — each selected to deliver maximum transmission, minimal absorption, and long-term environmental stability.
IR Component Types
A broad portfolio of precision infrared optical elements
IR Lenses
Plano-convex, plano-concave, meniscus, and aspheric lenses in germanium, ZnSe, ZnS, and silicon. Available with BBAR, DLC, and hard carbon coatings for MWIR and LWIR bands.
IR Windows & Substrates
Precision-polished flat windows for thermal cameras, vacuum chambers, and process monitoring ports. Supplied in Ge, ZnSe, ZnS, Si, CaF₂, BaF₂, and sapphire to customer specification.
IR Mirrors
Gold, protected gold, and dielectric IR mirrors for beam steering, off-axis parabolic focusing, and cavity design across NIR to LWIR. Custom radii, substrates, and coatings available.
IR Beamsplitters
Plate and cube beamsplitters for SWIR, MWIR, and LWIR laser lines including 1064 nm, 2 µm, CO laser (5 µm), and CO₂ laser (10.6 µm). Polarising and non-polarising variants.
IR Prisms
Dispersing and reflecting prisms in ZnSe, germanium, and silicon for FTIR instruments, spectroscopy systems, and IR beam manipulation applications.
