ASD Instrument Controller Software Share Request

January 17, 2018


We are often asked for names of ASD users who have written their own instrument controller software, but alas…your deeds have gone unpublished - until now! If you have written your own instrument controller software to control an ASD spectrometer we want to hear from you.

What problem or need were you trying to address with your code and what were you able to accomplish?

QualitySpec Trek Report - ASD Goetz Instrument Support Program

August 02, 2017

Written By Leena Leppänen, Finnish Meteorological Institute, Arctic Research, Sodankylä, Finland. 2017 Winning Goetz Instrument Support Program Project Title: "Spectral reflectance of snow in Sodankylä, Finland" 

ASD's QualitySpec® Trek (QST) was used for reflectance measurements of natural snowpack in Sodankylä. A total of 163 spectrums were measured, including 6 test measurements in the beginning. Usually, measurements were made in Intensive Observation Area (IOA) where snow pit measurements are made weekly in addition to several automatic measurements of snow and meteorological properties (Figure 1).


Figure 1. IOA measurement field. Location of snow pit area is marked with red circle. Snow pits were made to the same area but different spot every measurement occasion. Snowpack is suspected to be homogenous in that area.

The manual snow pit measurements includes definition of layers and for each measurement of grain size and type, hardness and wetness, and density profile and specific surface area (SSA) profile with IceCube, snow depth and bulk snow water equivalent (SWE). Automatic snow measurements at the site are snow depth, SWE, snow temperature profile every 10 cm, and snowfall intensity with particle size. More information about snow pit measurements and snow conditions in Sodankylä can be found from Leppänen et al. 2016.

Vertical profiles from snowpack were measured with QST to research vertical variability of reflectance in snowpack (Figure 3a). Measurements were made approximately every 2-3 cm, and 4-5 cm in depth hoar layer where coarse grains existed. Snowpack surface was measured also from top (Figure 3b). Forest snow pit profiles were measured for research of horizontal spatial variability (Figures 2a, 2b).

ASD instruments in action at the AGU Fall Meeting 2014

December 12, 2014

If you are attending the American Geophysical Union (AGU) fall meeting in San Francisco, CA, USA, be sure to visit us at booth #1923, for a hands-on demo of the new QualitySpec Trek, our newest full-range hand-held spectrometer.

QualitySpec Trek appears in an episode of the television show "Bones"

November 07, 2014

The QualitySpec Trek made its acting debut on the television show "Bones" in an episode that originally aired Oct. 30, 2014 in the United States. The episode centers around a forensic scientist convention where attendees want to help determine the cause of death for a body found in a stairwell. One of those attendees attempts to offer the use of his QualitySpec Trek. 

NEW! Introducing the QualitySpec Trek full-range hand-held contact spectrometer!

September 23, 2014

We are happy to announce the release of QualitySpec Trek, our first general purpose, full-range (350-2500 nm), hand-held contact spectrometer. QualitySpec Trek leverages the TerraSpec Halo mineral identifier's innovative design and superior performance to transform the way full-range spectra are collected; in the lab, on the job site, in the field.
