The BL138 Series delivers a high-intensity linear backlight solution for demanding machine vision applications. It excels in highspeed web material imaging with line scan cameras and serves as a powerful general-purpose bar light when highly diffuse front illumination is required.

Equipped with ultra-high power industrial-grade LEDs, the BL138 Series can operate in both exceptionally bright strobe and continuous modes, depending on the control configuration. Its passive finned heatsink design optimizes thermal dissipation without active cooling fans. For applications exceeding 24 inches, optional uniformity balancing every six inches ensures consistent exposure across the entire active area.
