Welcome to StockLG

Use the tabs above to define your optical system specifications and constraints. Each tab focuses on a different aspect of your request:

  • Specifications – Define the main system parameters and select the desired design type.
  • Dimensions – Enter the physical dimensions and spacing parameters relevant to your setup.
  • Distortion & Telecentricity – Specify performance targets for distortion and telecentricity.
  • Stock Glasses – Choose preferred suppliers or component catalogs to be used in your design.
  • Submit Request – When all sections are complete, submit your design request for processing.

Working with Constraints

All constraints listed in the tool - except for “Max. total track length” - can be temporarily disabled by setting their value to zero (0).
When a constraint is disabled, the corresponding field will be marked as not applicable (n/a) and greyed out.
To re-enable a constraint, simply enter a non-zero value again.

⚠️ Warning: the current f-number is below f/0.8, which is considered very fast and may be impractical to design.

Please adjust Focal length or ENPD to ensure a feasible design.

⚠️ Warning: the current image space NA exceeds 0.8, which is considered very high and may be impractical to design.

Remember, the image NA is calculated as:
Image NA = Object NA ÷ |Magnification|

Please adjust Magnification or Object NA to ensure a feasible design.

❌ Error: The total track length is fully occupied by spacing constraints.
No space remains for optical elements, please revise your inputs.

(Remaining space = Total track length − Min. back focal length − Min. clearances before & after stop, if applicable)

⚠️ Warning: Less than 20% of the total track length remains for optics.
This may severely restrict the design and limit what can be achieved.

(Remaining space = Total track length − Min. back focal length − Min. clearances before & after stop, if applicable)
