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 greyed out.
To re-enable a constraint, simply enter a non-zero value again.

Design Type
Aperture stop location
Wavelength range (um)
and

❌ Both Wavelength values must be numbers between 0.2 and 16 microns.

Image diameter (mm)
0.00
Image diameter (mm)
0.00
Image diameter (mm)
0.00
Focal length (mm)

❌ The Focal length must be a number greater than or equal to 1.

Type of projection
0.00

⚠️ 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.

ENPD (mm)

❌ The ENPD must be a number greater than or equal to 0.1.

FFOV (deg)

❌ The FFOV must be a number between 0.3 and 100.

Magnification

❌ The Magnification must be a number between -20 and -0.05.

Object space NA

❌ The Object NA must be a number between 0.001 and 0.25.

0.00

⚠️ 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.

Object size (mm)

❌ The Object size must be a number between 0.1 and 100.

Object distance

❌ The Object distance must be a number between 1 and 1000.

Max. total track length (mm)
0.00

❌ The Max. total track length must be a number greater than or equal to 5.

❌ 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)

Min. clearance before stop (mm)
Min. clearance after stop (mm)
Min. back focal length (mm)
Max. back focal length (mm)
Max. distortion (%)

❌ The Max. distortion must be a number greater than or equal to 0.

Max. image-telecentricity error (deg)

❌ The Max. image-telecentricity error must be a number greater than or equal to 0.

Max. object-telecentricity error (deg)

❌ The Max. object-telecentricity error must be a number greater than or equal to 0.

Max. number of components

❌ The Max. number of components must be a number between 2 and 6.

Stock lens catalog(s)

❌ You must select at least one stock lens catalog.

Assembly Tube Diameter
Stock components

❌ You must select at least one stock lens component.
