Physically, TO-66 is the largest LED package type in the Ushio Epitex SWIR collection. The colossal metal construction houses sixty small 350 μm² chips or sixteen 1 mm² chips on one 31.5 mm x 17.53 mm package. This multi-chip LED type delivers a maximum 10 Watts of power per package, especially for customers who require even more power than the SMBB 3-chip packages.

A choice of several lenses presents an opportunity to select from wider or narrower viewing angles. Spanning SWIR wavelengths from 1050 nm to 1750 nm, TO-66 LEDs are produced in standard increments of 100 nm. In most cases, an epoxy lens type is sufficient; however, due to the absorption of 1750 nm by resin lenses, a -110 glass lens will be recommended for this wavelength.

By sharing detailed application information and preferred device specifications with Ushio, our experts can deliver a TO-66 LED recommendation that is unique to your application.
