The OreXpress Miniprobe has a 3 mm spot that allows geologists in the field or the core shack to identify minerals of interest. The Miniprobe is designed to work with the OreXpress field spectrometer for portable mineral identification and analysis. The Miniprobe allows geologists to identify minerals in a smaller area than the traditional 10 mm spot available with the mineral contact probe.... 1. It is easy to hold and use with an external trigger for fast and comfortable scanning. 2. Unique, comfortable low reflectance, impact resistant ABS thermoplastic body 3. Light touch, tactile feel, push-button trigger for data collection 4. Metal clad fiber optic cable with quick disconnect 5. Lightweight, easy to carry and easy to hold and use all day 6. 5W halogen light source for built-in illumination 7. Plugs directly into the OreXpress or other spectrometers or spectroradiometers 8. Ideal for mineral reflectance studies especially on very small sample features The Miniprobe is indispensable for samples where minerals are only present in tiny areas. It allows geologist to focus on smaller areas of interest in a sample or core and see accurate, high resolution scans. Combined with the EZ-ID mineral identification software it can help identify important mineral alteration and isolate components in mixtures. The oreXpress spectrometer delivers: 1. Rapid data spectra collection in the field 2. High signal to noise ratio for improved reflectance values 3. Fast start-up and use with no optimization step required between scans 4. Sturdy construction to handle field conditions 5. Reliability with no moving optics and a robust metal clad fiber optic cable connector with easy-disconnect fiber The oreXpress with EZ-ID matches your unknown target mineral against a known spectral library. EZ-ID is available with the USGS library and the SpecMIN library from Spectral International. For literature on the subject, see http://www.spectralevolution.com/resources.html
