what's new



stokes ellipsometer LSE-USB
with convenient USB interface is based on advanced StokesMeter™ technology (previous winner of Photonics Spectra and R&D 100 best new products awards). The unit's basic design offers unprecedented ease of use, precision and instantaneous measurement.

stokes microspot ellipsometer LSE-MS 
offers a 15 micron measuring laser beam diameter, manual  2x2 inch micrometer positioning stage and a CCD camera for viewing the area of measurement on your PC. Areas as small as 15 X 45 micron can be viewed and measured using advanced StokesMeter™ technology

two angle two wave stokes ellipsometer LSE-2A2W
automatically measures with both a red laser at 70° and green laser at 60° incidence angle.  The 2 angle 2 wave capability determines thicker film thickness and gives refractive index measurements over a wider thickness range.  Helps with difficult to measure films. Get many of the advantages of spectroscopic ellipsometers without the complexity.

ellipsometer upgrades for Windows
Older Gaertner ellipsometer models L116, L116A, and L116B with Hewlett Packard computers can be upgraded to computers with Windows software. Old WAFERSKAN models L115A, L115B and L115C with Hewlett-Packard computers can be upgraded to Windows computers using new LGEMP software giving  2D/3D color image maps.

solar cell / scattering sample measurement option L-SCAT
Rough scattering samples common in the solar cell industry are difficult to measure accurately with most ellipsometers because of the loss of signal strength and depolarization of the measurement beam.  Gaertner Stokes Ellipsometers measure all 4 stokes parameters s0, s1, s2, s3. for a complete state of polarization measurement  giving highly accurate film thickness and index together with a hardware modification.

xy digital measuring microscope W126-6x4
The model W126 provides 6 x 4 inch measurements using linear read heads and a Quadra-Chek readout. Geometric capabilities include radius-diameter, centerline, polar/cartesian, skew alignment, linear error correction, inch/metric conversion to handle most of your measurement needs. 

micrometer slide with electronic readout
The model M303LE has a 4 inch range, linear encoder and inch/metric digital electronic readout standard.
