Winlens Basic Features

System

• 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

Materials

• 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
• Child graph of index/transmission v wavelength

Surfaces

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

Editing

• 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
• copy/insert part or all of file on disk  

Option to update calculations, graphs and tables

either: 

• automatically after each change
• on demand

Enhanced graphics

• zoom in/out
• pan
• high resolution printout (uses printer full resolution)
• output to DXF
• applies to all graphs & drawings

Analysis (results in tables and graphs) 

• lens drawing: zoom in/out and customise to show different features, rays etc. and DXF  output
• Seidels bar graph: user selectable graphing of seidel contributions, cumulative & sensitivities, along with optional lens data and paraxial quantities.
• Y-Ybar diagram
• optical path difference OPD 
• field (astigmatism, distortion and colour)
• longitudinal aberrations
• transverse ray aberration TRA
• spot diagram
• spot diagram full field
• modulation transfer function MTF
• chromatic aberration
• full field distortion
• 3D wavefront plot
• paraxial data for system
• xparaxial data for components
• paraxial ray trace
• Seidel analysis (including aspherics and pupil)
• ray fan table
• single ray table
• Gaussian beam table
• Gaussian beam graph
• alternate glass finder
• internal absorption table
• transmission graph
• transmission table
• weight table
• sensitivity table - paraxial, Seidels or Gaussian beam

Tables/Graphs features

• multiple copies of most graphs and tables available
• zoom friendly graphics - show one, some or all zooms, overlayed in separate frames
• ability to freeze copies of graphs or tables as an audit trail

Autofocus

• autofocus to minimise OPD or TRA
• averaging over all fields (not just axis)
