Frequently asked questions (FAQ)

Are HS10 and HS20 interchangeable?

Yes, they use the same external case dimensions, mountings and connectivity. 

What are the recommended optics that I should use?

The recommended optics are dependent on the axis length:
• 0 to 30 m = Standard linear optics
• 0 to 60 m = Long range optics
Only one set of linear optics is required per axis. 

Should I use long range ducting for my application?

The long range ducting system is recommended in all applications although the HS20 laser system can be used without it. It is intended to protect the beam path from debris and coolant, whilst also providing a stable thermal environment for laser beam measurement.  

What class laser is used within an HS20 system?

The HS20 laser head contains a Class II (maximum output power ‹1mW) visible Helium/Neon laser. 

When running a machine along the axis I lose signal strength from the laser, why is this?

It is most likely to be due to poor alignment or optical components not being adequately fixed to the machine. Ensure that the HS20 laser head is aligned with the machine axis. Full details are given in the manual. It is essential that the optics and laser head are secured and that they do not move when the machine is in use.

Application notes

  • [1.00 MB] [1.00 MB] Application note: HS10 operating speed

    The maximum operating velocity of an HS10 is up to 1 metre per second with a standard retro reflector interferometer. This is, however, dependent on the resolution the HS10 is set to. To get the optimum performance from the HS10 laser scale system it may be necessary to change the clock speed of the HS10.
