PreDesigner from Qioptiq Photonics is an elegant lens calculator with sliders & touch-editable ray diagram & thin lens nomogram. Visualise key optical parameters and their interactions. Precise calculations for specific design tasks. Your choice of key parameters & units.



PreDesigner Lens Calculator features
• select conjugate field & aperture parameters to suit your specific task
• adjust parameter values with editbox or slider with automatic results/drawing update
• calculate conjugate values: object & image distances focal length track magnification
• calculate field values: object & image heights / angles - field of view [fov]
• calculate aperture values: stop radius f number [f/#] and numerical aperture [na]
• understand simple ray diagrams and the lens nomogram
• understand basic geometric optics - see how these parameters change in real time with the sliders and interactive ray diagrams
• your choice of units [metric and/or imperial]
• do ‘back of envelope’ calculations at start of a specific lens design task
• estimate space envelope
• obtain depth of field [dof] data for a camera
• social features: share data/screen captures. see Qioptiq tweets.
In short this is a simple powerful highly interactive ‘lens/mirror equation’ app


How to use PreDesigner Lens Calculator
Choose three distance and size parameters from a full range of options. Choose an aperture parameter. Enter the values for the four parameters and see:
• table showing all the optical parameters values
• ray diagram showing object lens & image cardinal points etc
• nomogram [graph showing the relation between object image distances and focal length]

Tap a parameter name to see its linked slider. Long press the same name to see/edit the slider limits. Use the slider for quick precise value changes with no typing.

The ray diagram & nomogram are gesture enabled so you can drag key features to edit focal length object distance & size image distance & size aperture or principle plane distance. Graphics up-date as you drag - a true ‘lens equation’ visualiser!

Lens / mirror mode. Lists of standard f/#'s & sensor dims.

Advanced options include
• principal plane separation
• different refractive index in object & image space
• choice of ray diagram styles


Who PreDesigner Lens Calculator is for
This is a scientific app of use to people in education industry and leisure:
• lens designers – especially for the first stage of design tasks
• optical engineers laser engineers
• university and industrial researchers
• university lecturers giving geometric optics courses at degree or higher
• university students taking Engineering or Science Majors
• high school teachers and physics students: A Level International Baccalaureate Abitur (Allgemeine Hochschulreife or Matura) AP Physics Physics SAT etc
• astronomers photographers & camera enthusiasts
In fact anyone with an interest in optics!
