LAS-CalcuLens Inspection™

SKU: calclens265

High-Resolution Digital TIR Probe & Software for Precision Housing/Cell Alignment


CalcuLens™ software enables LAS™ system users with non-contact and instant sub-micron measurements for any lens surface, including cylindrical, aspherical and spherical lenses with coated or uncoated surfaces. It accommodates radii of curvatures from ±2.0mm to infinity. It also allows assembly personnel to save alignment results at any time during assembly.

CalcuLens™ v2.6 software introduced automatic centroid detection and tolerance zone marking, which improves both the speed and repeatability of TIR measuring. A new, easy-to-use, calibration utility is now also included.

LAS™ systems incorporating CalcuLens™ software switched to a digital camera in 2011. This resulted in an order of magnitude improvement in resolution and repeatability due to the pixel being approximately 1/3rd the size of the previous analog camera. High sensor sensitivity and access to additional camera controls aid in capturing images from coated optics even with low reflectivity at the source frequency.



Calibration Utility:

  • Calibrate by following interactive step-by-step instructions

  • Print final result.

  • Self-documenting ISO compliant

  • New precision grade calibration optics increase accuracy and reduce process steps

Linear auto-move:

  • Automatically move to the desired surface reflection

  • *Requires updated motion control hardware*


  • English, Metric, Linear, Angluar

  • Convert with original unit retention for future calculations

Automatic centroid:

  • Automated capture and calculation

  • Manual capture when necessary

Graphic tolerance zone:

  • Tolerance limit guide circle diameter equal to tolerance spec on that surface

  • Provides target crosshairs on screen

Lens data:

  • Download from Zemax design software or enter lens specs manually

Glass index:

  • Industry glass index library

  • Custom index entry

Gas index:

  • Air, nitrogen, vacuum

  • Custom index entry

CalcuLens™ v2.6.5 Software Options:

CalcuLens™ Assembly Software: The base software package standard on every LAS™. Used for incoming inspection at the component level (lenses and mechanics), alignment and measurement during sub-assembly of lenses/lens cells, alignment and measurement during overall optical system assembly. Recommended for all LAS™ users to align, measure and document the assembly process as it progresses lens-by-lens. Suitable for production environments, R&D development projects, quality control processes and more.


  • Reflection based measurement from the top and/or bottom surface of a single lens

  • Submicron TIR or arc sec values

  • Lens-by-lens measurements


CalcuLens™ 3D Software: An add-on capability to the base software package that provides measurement data for the location of the centers of curvature for the lens being assembled or qualified. Recommended for LAS™ users that require more engineering data to feed back into optical models or require separate tilt and de-center values for the lens alignment as the assembly progresses lens-by-lens.


  • CalcuLens™ Assembly functionality included

  • Measure separate tilt and decentration values of single lens

  • Plot lens centers of curvature

  • Lens-by-lens measurements


CalcuLens™ Inspection Software: An add-on capability to the base software package that extends the Assembly and 3D capabilities to measure and quantify the alignment of lenses embedded in an already assembled system. Provides the same data output as the 3D software but allows measurements for lenses below the top lens of the optical system under test. Recommended for LAS™ users that require measurement of an assembled system. Suitable for qualifying a lens assembly, diagnosing problems, or other situations where the lens alignment comes into question.


  • CalcuLens™ Assembly functionality included

  • CalcuLens™ 3D functionality included

  • Embedded lenses in a finished assembly measurements
