PreDesigner is an elegant lens calculator with touch-editable ray diagram. Visualise key optical parameters and their interactions. Precise calculations for specific design tasks.

• Help you to understand basic geometric optics. Show how focal length, object and image distance / height / angle, track, magnification, field of view [fov] work together.
• Help you to understand how aperture, f number [f/#], numerical aperture [na] interact. Provide depth of field [dof] data for a camera. Help you to assess the likely space envelope.
• Help you to understand simple ray diagrams
• Help you to model the first stage of a specific lens design task. Provide range of key parameters that other lens calculators don’t offer.
In short, this is a simple, highly interactive ‘lens/mirror equation’ app. If you need or want any of these features, then PreDesigner is THE tool for you!

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 of all the optical parameters
• ray diagram showing object, lens & image, cardinal points etc

The ray diagram is 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 drawing up-date as you drag - a true ‘lens equation’ visualiser!

PreDesigner is a scientific app, of use to people in education, industry and leisure:
• Lens designers – especially in the first stage of design tasks
• Optical engineers and laser engineers
• Researchers
• University lecturers and students taking geometric optics courses at degree or higher - Engineering or Science Majors
• High school teachers and physics students: A Level, International Baccalaureate, Abitur (Allgemeine Hochschulreife or Matura), AP Physics, Physics SAT etc
• Photographers, Camera enthusiasts & Astronomers
• In fact, anyone with an interest in optics

Options include mirror mode, principal plane separation, different refractive index in object and image space, choice of ray diagram styles and more.

Qioptiq Photonics has been developing optical design software for over 20 years, for use by the R&D department and by customers worldwide. Qioptiq’s lens design programs include:
• WinLens3D - full optical design program
• GlassManager – highly customisable optical glass database program
• PreDesigner – paraxial & Gaussian beam analysis tool (Lens Calculator is derived from PreDesigner)
• MachVis – Machine Vision lens selector – calculates the necessary optical parameters and finds the right lens for your machine vision application

The full optical design suite, WinLens3D, is available in the Qioptiq Q-Shop: www.qioptiq-shop.com/en/Precision-Optics/Optics-Software/Winlens/Software-package-WinLens-3D.html

Qioptiq designs and manufactures photonic products and solutions that serve a wide range of markets and applications in the areas of medical and life sciences, industrial manufacturing, defence and aerospace, and research and development.

The company is known for its high-quality standard components, products and instruments, its custom modules and assemblies, its leading-edge innovation, its precision manufacturing and its responsive global resourcing.

Through a series of acquisitions, Qioptiq has an impressive history and pedigree. It benefits from having integrated the knowledge and experience of Avimo, Gsänger, LINOS, Optem, Pilkington, Point Source, Rodenstock, Spindler & Hoyer and others.

    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 hei
