# Laser positioning

> Lasers projected onto the turntable that show where to place a product so it sits at the centre of rotation.

Also known as: positioning lasers, cross laser, laser centring, laser centering. Category: Hardware.

Laser positioning uses cross or line lasers projected onto a turntable to mark the centre of rotation, so an operator can place each product in the same position quickly. A well-centred product does not drift or wobble in a 360 spin.

## How PhotoRobot uses it

PhotoRobot turntables use built-in cross lasers, with cross or grid options on some machines; a laser controller drives 1 to 20 positioning lasers. Lasers are switched off automatically during capture on systems such as PINK so the laser line does not appear in images. The [laser centering guide](https://www.photorobot.com/manuals/laser-centering-guide) describes how to align the lasers to the true centre of the plate.
