Crystal IS adds TO-39 package with flat window to line of lattice-matched commercial UVC LEDs

Crystal IS Inc of Green Island, NY, USA, an Asahi Kasei company that makes proprietary ultraviolet light-emitting diodes (UVC LEDs) grown pseudomorphically (strained) on aluminum nitride (AlN) substrates, says that its newest Optan product is a deep UV LED in a TO-39 package with a flat window. Samples are available now.

Like the recently introduced Optan ball lens (BL) and surface-mount devices (SMD), the high-performance UVC LED is based on native AlN substrates using Crystal IS' proprietary technology. Claimed to be the only lattice-matched commercial UVC LED currently available, Optan provides a technology platform for increased detection sensitivity, proven to overcome limitations of other UVC LEDs in the market as well as traditional UV lamps including deuterium and xenon flash lamps, the firm says.

Crystal IS says that the Optan Flat Window:

  • has a wider viewing angle than other Optan packages (for easier alignment to fiber-coupled designs in analytical and life-science instruments);
  • provides users with high reliability and performance, and lowers the cost of ownership in sensors for process monitoring (a requirement in applications in industrial processes and pharmaceutical manufacturing); and  
  • does not focus the light from the chip (since the flat window packaging preserves lambertian emission), so users have the maximum flexibility and full control over the optical path to fit their needs.

"As soon as we introduce a new Optan package, our customers come back with even more ways they'd like to replace traditional UV lamps with UVC LEDs," comments CEO Larry Felton.

The Optan Flat Window UVC LED can be used to monitor processes in industrial manufacturing; clean-in-place operations in the food and beverage processing industry; and in chromatographic processes used in protein purification and pharmaceutical manufacturing. In these processes and industries, UVC LED-based sensors have been shown to lower costs, increase productivity and meet regulatory and quality control requirements, the firm says.
