20km Ultra Long Range LRF Module

Name: 20km Ultra Long Range LRF Module
Brand: Hainan Eyoung Technology Co., Ltd.

LRF Model: EYC-11A

Unlike other small and lightweight LRF modules among Eyoung's laser rangefinder module line-up, this one is medium-size designed to match its high range performance of up to 20km on vehicle (2.3m×4.6m). The small beam divergence of 0.3mrad offers a capability of intensive and stable laser emitting, meanwhile the large diameter (77mm) of laser receiving aperture ensure more reflected laser echo to be gathered. It is highly recommend to be used in ultra long range applications such as maritime electro-optical surveillance system.
