Find the right product for the task
| Task or choice | Product route | Why it matters |
|---|---|---|
| Centre or aim | Crosshair / quadrant / concentric circles | Place a visible reference in the optical image to compare centre, direction or symmetry. |
| Measure length or angle | Graduated scale / crossed scale / protractor | Select the measured quantity and calibrate specimen-plane length when using eyepiece divisions. |
| Count or sample | Grid / point array / stereology pattern | The pattern supports a sampling method; area counting alone does not define a liquid volume. |
| Compare a feature | Particle / grain / inclusion references | Match the comparison pattern and microscope setup to the particular examination method. |
Bring the selected options into one specification
- Pattern artwork and reference features
- Clear aperture and substrate dimensions
- Feature size, scale and registration
- Contrast, cleanliness and inspection criteria
Put the right reference in your field of view.
TL OPTIK turns scales, crosshairs and precision grids into instrument components. For observation, alignment or counting, define the useful field, line width and graduation spacing first. We then review substrate dimensions, pattern orientation and mounting references against your instrument drawing.

Selection notes
Reticles and graticules introduce scales, crosshairs, circles or grids into an optical field for observation, alignment and measurement.
