Product information

Description

The Yermos Kolimator laserowy DO-GSO is a compact laser collimator designed for checking and adjusting the alignment of optical systems. It projects a precise laser beam that helps identify misalignments in telescopes and other instruments with reflective or refractive optical paths. The device is intended for quick verification of optical axes and mirror centring, allowing users to perform fast, repeatable collimation checks without complex tools.

Advantages

The collimator provides a stable, well-defined beam that simplifies identification of decentre and tilt in optical components. Its compact form factor and straightforward operation make it suitable for use in the field or a home workshop. The tool reduces the need for trial-and-error adjustments and supports repeatable alignment procedures for both primary and secondary mirrors or lens assemblies.

Suitable for

  • Amateur and hobbyist telescope maintenance and setup
  • Quick on-site alignment checks of reflecting and refracting instruments
  • Verification of optical axes during mirror or lens installation
  • Routine inspection and adjustment before observation sessions

Key specifications

  • Laser output: visible red beam suitable for alignment tasks
  • Form factor: compact, handheld/insertable design for telescope focuser or holder
  • Beam quality: narrow, well-defined spot for precise centring
  • Power: low-power class suitable for alignment use (eye-safety practices required)
  • Operation: simple on/off control for quick checks

How to use

Insert the laser collimator into the telescope focuser or mount it in the appropriate holder so the beam is directed along the optical axis. Turn the device on and observe the beam position on the primary mirror or at the return point used for your collimation method. Adjust mirror tilt and centring screws or lens mounts until the beam aligns with the desired reference marks or the optical axis. Repeat the procedure as necessary to achieve concentricity and correct tilt.

Usage recommendations

Use the collimator in a dim environment to easily see the laser spot, and avoid pointing the beam at people or reflective surfaces. Follow standard eye-safety precautions when working with visible lasers. For the most reliable results, combine laser checks with visual inspection through a Cheshire or star test when possible.
