Winlens Basic Features

Winlens Basic Features


  • handles systems with rotational or cylindrical symmetry as well as folded systems
  • component orientated - singlets, doublets, air-spaced doublets, triplets, blocks, mirrors, prisms, wedge plates
  • thin lens layout for pre-designs and starting systems
  • system can have unlimited components in multiple zooms (RAM limited)
  • each zoom can have different conjugates, field and apertures sizes and wavebands
  • import/export to/from files in other formats

Lens database

LINOS component database (with search - type, efl and radius) 

  • 31 1... biconvex lenses
  • 31 2... plano-convex lenses
  • 31 3... biconcave lenses
  • 31 4... plano-concave lenses
  • 31 5... meniscus lenses
  • 31 6... plano-concave cylindrical lenses
  • 31 8... plano-convex cylindrical lenses doublets
  • 03 3... air-spaced achromats and laser monochromats
  • 32 2... positive achromats / NIR doublets
  • 32 5... negative achromats
  • 33 *... prisms and wedge plates 

additional lens library (to be installed separately) contains:

QIOPTIQ Photonics system files

  • aspheres
  • ball lenses
  • beam expanders
  • condenser systems
  • eyepieces
  • microprojection lenses
  • microscopic lenses

and several designs from LINOS Photonics & general literature

Prism database, grating database


  • glass database from major suppliers (with category/sort)
  • special user defined glasses
  • models melt glasses - only needs melt index at two wavelengths! 
  • allows for user selection of materials in object/image space and between components

Active Glass Map

  • Highlight glasses used in the current system
  • Update system glass by simple click on map
  • Show/hide glass names and other options
  • Select display variables for X & Y axes
  • Colour code the glasses with another property (e.g. density or transmission)
  • Display subset of the glasses (powerful search)
  • Find single named glass
  • Zoom into the glass map
  • Logs of axis definitions, colour codes & searches
  • Generate high resolution printout

  • spherical, conic and aspheric (power series, normalised power series or Zernike)
  • reflective, refractive or diffractive [gratings, HOEs]
  • cylinders and toroids
  • LINOS coatings


  • system data editor for component view
  • surface by surface editor
  • system parameters editor (conjugates, aperture, field, waveband   (up to 5 wavelengths) etc.)
  • editors for custom components (with tool fitting)
  • pickup definitions (component, surface, space, seperations etc.), scaling and chains   allowed
  • sliders for quick changes to system parameters and simple optimisation
  • drag and drop LINOS components and materials
  • solves and tools to scale and reverse system or parts of system
