SAMPLE PREPARATION LAB

Intrumentation

MCL maintains a complete sample preparation lab for mechanical cutting and polishing. Click here for a complete list of instrumentation available in the sample prep lab.

Technique Description

In order to produce the flatness and smoothness required to study materials (e.g. non-linear optical measurements, micro lens arrays for beam focusing, optical spectroscopy, scanning probe microscopy, roughness testing, orientation imaging microscopy, scanning electron microscopy, energy dispersive spectroscopy, dielectric tests/sputtering needs or other), it is necessary to cut your sample to a workable size. Polishing your sample requires a choice of the best tool and grit to flatten it. That accomplished, a series of smaller and smaller grit sizes must be used essential to produce the mirror-like shine necessary to allow testing, etc.

Sample Requirements/Specifications

Samples must be 2mm deep or less for use of the dicing saw
For optical polishing, bring at least 3-6 samples of the same depth or sample dummies of the same size and type (helpful but not necessary)
Know the composition of your sample and it’s tolerance of heat, water, acetone and alcohol

User Policies, Procedures, and Training

While most of the lab equipment is available and may be used after normal working hours, the dicing saw and sonic mill may not be used after hours. A key is available to those who want to work in the lab after hours. Researchers and students may be trained on all equipment in general except for the Accutom. Each person is trusted to be responsible to sign into Portal for lab space in the Cutting and Polishing Lab at MRL when using any of the consumables or equipment. Students are also expected to follow MRL safety rules in the lab. New students must be trained on lab equipment by the lab manager. Should a user break anything, he/she should report the incident to the lab manager to discuss any charges that may result. Common sense and courtesy is expected of each person working in the lab.
