Exosens ECHO image intensifier tubes (formerly Photonis) are designed for commercial customers seeking strong low-light performance at a practical price.

The collection includes ECHO14 with a FOM of 1400–1800, ECHO14+ with a FOM of 1800–2200, ECHO with a FOM of 1800–2200, and ECHO+ with a minimum FOM of 2200. The range is available in P43 green or P45 white phosphor, with fast auto-gating and 180 kΩ external gain control as standard.
