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

    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!

    Rubbish. Way too complicated

    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

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

    It does exactly what it says. Invaluable for lens calculations
