Applications

 

Automated variable angle scans for simple, repeatable measurement of absolute transmittance and reflectance

Accurate characterisation of multilayer and anisotropic films, at every substrate position

Ready verification of component QC specs at multiple angles, and performance characterisation at angle of use

Accurate characterisation of multilayer and anisotropic films, at every substrate position

Quantifiable performance metrics to support formulation, colour matching and security feature verification

 

Tailor your TAMS

The TAMS unit features five detector units which are easily swapped to adapt to any sampling challenge.

 

Select a direct or sphere detector:

 

  • Sphere detectors maximise accuracy. Ideally suited for thin films[FA4.1], slightly curved samples and prisms. Measure directional reflectance and transmittance
  • Direct detectors maximise sensitivity. Characterise patterned surfaces and diffuse coatings. Evaluate angular resolved scattering including BRDF/BTF.

 

Combine sphere or direct detector design with control over wavelength range:

 

  • Si only to measure 190-1150 nm
  • Si/InGaAs to measure 200-2600 nm

 

Features

PerCal-Plus-Icon-1
0.01° resolution. 0.02° accuracy. Fully automated.

Measure challenging samples with angular dependencies with confidence. The sample and detector rotate independently using a precise goniometer design, giving you angular resolved absolute reflectance/transmittance data from 5° to 80°. From 6-inch wafers to 150 × 150 mm samples, every angle lands exactly where you set it.

PerCal-Plus-Icon-2
Complex angle-resolved measurements with minimal set-up.

TAMS removes the need for manual angle changes, repeated repositioning and hours at the bench. With TAMS, you define the measurement and the system does the rest, with fully automated sample and detector positioning. Combine with the autosampler, which runs from the same TAMS interface, to increase throughput. Less setup, fewer operator errors, and more of your day spent on results.

PerCal-Plus-Icon-3
Measure from positive and negative angles of incidence

The TAMS facilitates reflectance measurements from both positive and negative angles of incidence, accounting for more angle-dependent behaviour at higher AOI, and characterise asymmetric or imperfect materials.

PerCal-Plus-Icon-4
One instrument, any measurement

TAMS is one of the swappable accessories on the LAMBDA 850+/1050+ platform, alongside integrating spheres, detector modules and the General Purpose Optical Bench, and it changes over in minutes. It occupies only the detector compartment, and operators can exchange the detectors for modules optimized for each application, from sphere sets for maximum accuracy to standard sets for maximum sensitivity. With an upgradeable detector configuration and an autosampler that handles wafers and multi-sample holders, one system adapts to your next material, not just your current one.

 

Expand your TAMS unit

The TAMS have a variety of accessories to expand the capabilities and measure additional sample types
