Qioptiq Lens Calculator

Qioptiq Lens Calculator


PreDesigner from Qioptiq Photonics is an elegant lens calculator with 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.


PreDesigner Lens Calculator features
• select conjugate, field & aperture parameters to suit your specific task
• 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 interactive ray diagrams
• 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, news and ‘like’
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 all the system values in:
• 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]

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

Select lens or mirror mode. Use popup lists of standard f/#'s & sensor dimensions.

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


Who PreDesigner Lens Calculator is for
PreDesigner 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 (All-gemeine Hochschulreife or Matura), AP Physics, Physics SAT etc
• astronomers, photographers & camera enthusiasts
In fact, anyone with an interest in optics!

Recent changes:
[v6.0 Dec 2014] User interface refreshed

Undo, Expand, Drawing-type, Reset [to default lens] & Share in Action Bar

New customisations especially for users with smart phones:
- button to show/hide key parameter area
- button to show/hide graphics [in single column mode] and different sections of the results table

Better display of aperture related results, indicating when selected value is ‘too large’

No new permissions needed after those added for v5.0

Really useful app Robust, flexible & accurate. I like the new nomograph - I'd not come across that before - its a good way to explain the lens equation purely graphically. Definitely one to keep!

A unique tool for optical instrument design This tool allows you to calculate the object size that will fill a given CCD at a given distance with a given lens, as well as many other useful parameters such as the depth of field. You enter just the focal length, object distance, image height (CCD height) and the f-number (or stop radius). The latter is used to calculate the depth of field. My only criticism is that it is more complex than it need be. Seriously, you don't need to adjust these parameters by pulling on a diagram - just enter the numbers. Then the ray diagram is superfluous. There is a (too) long help file, but it doesn't actually define the parameters. There a diagram would be helpful, with the formulae used for the calculations. It could even link to Wikipedia definitions of the optical parameters. But it is uniquely useful and appears to give physically correct results. Good work!

Great learning tool Manages to pack some complex physics into a straightforward app that encourages experimentation.
