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!
