Temperature Control
By adding a cryostat or heat stage to the VASE for variable temperature studies, measurements can be conducted at temperatures as low as 4.2K and as high as 1000° C.
Linkam Standard Heat Stage
The Linkam Standard Heat Stage enables temperature-controlled ellipsometry measurements between -70° to 600° C with stability of 0.1° C. The heating chuck is 22 mm in diameter and can accommodate similarly sized samples. The heat stage features a custom lid with optical ports configured for ellipsometry measurements at 70° (AOI) to promote a controlled environment and enable purging when necessary.
Linkam High-Temperature Heat Stage
Linkam’s High Temperature Heat Stage is intended for applications that require temperature above 600° C. This heat stage enables measurements up to 1000° C by incorporating a crucible heater in the temperature stage. The crucible design is compatible with samples up to 17 mm in diameter and is sold with a custom lid that enables ellipsometry measurements at 60° (AOI). Customers with primary interest in temperature measurements below 600° C should consider the standard heat stage.
Lake Shore Cryostat
The Lake Shore Cryostat provides an ultra-high-vacuum, continuous-flow cryostat for variable temperature studies between 4.2 to 800 K. The cryostat can accommodate samples up to 25 x 25 mm and has optical viewports for ellipsometry measurements at 70° (AOI). The cryostat includes a temperature controller, turbo vacuum pump, custom table, and software for coordinating temperature control with ellipsometric measurements.
Liquid Studies
Several cells with optical windows for measurement through liquid ambient enable characterization of liquid/solid interface. Options include:
+45mL Electrochemical Cell
+270uL Liquid Cell
+5mL Liquid Cell
+Liquid Prism Cell
Sample Mounting Options
We offer a variety of sample stage mounts to accommodate your measurement needs. Our standard and small sample stages are provided with every ellipsometer, while the others are available as upgrades. Options include:
+Standard Stage
+Manual Translation
+Small Sample Stage
+Automated Translation
+Sample Rotator
+Auto-Z Stage
Focusing & Camera
Add focusing optics to decrease the measurement beam diameter. Our standard focusing option provides a 100 μm beam diameter. Our alternate focusing option provides a slightly larger, 200 μm beam diameter, but can be used during transmission measurements. Focusing optics are detachable for normal use. Add a camera to view the measurement spot on the sample and improve beam positioning.
