MEASURE controls and acquires data from popular spectrophotometers. It provides a well supported alternative to the software supplied by instrument manufacturers.

MEASURE LT supports Lambda 2 through 45  spectrophotometers as well as Lambda Bio/XLS, Ocean Optics, StellarNet, Agilent  (HP) 8453, and Cary 1-3 (100-300). Please contact us for further information.

  • One Program - Many Instruments. It makes no sense to run 3 programs for 3 instruments when all 3 can be controlled by FilmStar. (1.25 min)

  • Why FilmStar MEASURE?  Automation! That's why! See how FilmStar interfaces with ancillary hardware and software (like Excel). (2 min)

  • FilmStar Graph Automation. Graphics for QA and reports that far exceed the capabilities of instrument manufacturers' DAQ software. (2.75 min)

MEASURE is highly integrated with FilmStar DESIGN and includes the same FilmStar development modules. Instruments listed below are currently supported.  Please contact us for information about other models. Our Hitachi support is only for older models.

Why buy MEASURE when you already have PerkinElmer or Cary software?

The instruments listed below are directly supported. MEASURE users can run all; i.e. there is no additional charge for running a Lambda 900 and Cary 500 from the same computer. Please contact us for information about other models. MEASURE can also be utilized with other instruments as described here.

We are often asked about Shimadzu and Hitachi. Despite requests from their own sales teams, management refuses to document control codes and/or drivers. (Our Hitachi support is only for legacy models.) We recommend that you buy their instruments only if pleased with the current capabilities of Shimadzu's UVProbe or Hitachi's UV Solutions.  We are unable to provide automation support; the best we can do is import and convert spectral data files.

The FilmStar MEASURE fee covers all supported instruments. Program modes include
  • Transmittance (optical density)
  • V (relative) reflectance
  • VW (absolute) reflectance

Data file types include

  • Sample...scan of coated part
  • Baseline...scan of black sample, usually 0%
  • Reference...transmittance of empty sample holder, reflectance of uncoated optic, etc.
  • Standard...known values corresponding to reference scan

Data files may be loaded from disk, scanned or replaced by constants where appropriate. During data acquisition results are plotted on-screen in spectrophotometer units (usually 0-100%); final reduced values are displayed in physical units. Spectra can be utilized in DESIGN and INDEX for inverse synthesis.

Scan range is defined by wavelength/ wavenumber minimum, maximum and interval. In addition a Wave List can be specified; this is useful for filters with varying characteristics in different bands, i.e. broad-band blocking in two regions and narrow band transmission in another. The Wave List is also useful for devices whose specifications are defined at particular laser wavelengths.

Supported formats for measured data files include

  • .csv, comma-separated values
  • .dx, J-CAMP spectroscopy format
  • .spc, Galactic Industries GRAMS format
  • .xls/.xlsx, Excel (Excel not required)

Scan methods are edited in MEASURE and uploaded as required. While application software supplied by spectrophotometer manufacturers is not run during MEASURE operation, there are cases where manufacturer's driver software and FTG servers are utilized:

  • Perkin Elmer's Spectrum software (32-bit Windows) is required for legacy GX (2000) initialization and setup. Configurations are stored as Setup Files (*.set). The name of the setup file is subsequently specified in MEASURE. Since MEASURE can change scan range, only a few Setup Files are required in practice.
  • Click here for information about PE Spectrum FTIR. Spectrum Express users are advised to update to Spectrum 10.
  • Click here for information about Ocean Optics. Nicolet is supported via commands sent to OMNIC software.
  • Agilent's WinUV is required for Cary operation. Only a minimum installation (Cary System + Scan application) is needed.
  • Perkin Elmer's UV Winlab 6.04 or newer is required for Lambda 650-1050 operation with Universal Reflectance Accessory or Triple Detector Module.

PerkinElmer Lambda 16/18/19 is supported on 32-bit Windows XP/Vista/7 via a PCI board and custom cable. Click here for important details. The Agilent 8453 version supports NI IEEE-488 cards, LAN, and RS-232.

8453 Diagnostic Capabilities

The Agilent (HP) 8453 version of MEASURE adds diagnostic capabilities. This reduces or eliminates the need to use ChemStation software for diagnostic purposes. Unlike ChemStation, MEASURE supports the 8453's serial (USB) interface as well as LAN.  It also supports NI GPIB, but this offers no advantage for most users.

FFT verification

The Film Thickness Module enables users to quickly and automatically obtain film thickness in cases where films are thick enough to display fringes. Fringe counting and FFT algorithms are available. Applications include lacquers and similar coatings. While film index must be known with reasonable accuracy, the substrate index is not required. A calibration routine compensates for any resulting errors.

The program is intended as an industrial tool and runs standalone or as ActiveX client or server. It includes FilmStar BASIC and can run MEASURE or be run from MEASURE. It can be used directly with our Ocean Optics or Zeiss ActiveX servers. It provides smoothing algorithms for dealing with noisy spectra. Test spectra (with noise added) can be generated in FilmStar DESIGN.
