The all-weather LTHRAW with hermetically sealed construction: designed to operate under severe field conditions.

PLX’s All Weather Lateral Transfer Hollow Retroreflector™ (LTHRAW) greatly simplifies field operations like bore-sighting and validating electro-optical systems such as surveillance and targeting.

Its ingress protection rating of IP67 gives total protection from ingress and immersion between 15 centimeters and 1 meter in depth. Its ruggedized, sealed, vacuum-compatible design allows less skilled technicians to handle the unit safely.

The LTHRAW all-weather enclosure can be customized for the desired clear aperture and offset accuracy requirements. All PLX Lateral Transfer Hollow Retroreflector™ (LTHR) are perfect for folding parallel light and are available with sub-arcsecond accuracy.
